Last updated: May 2026. Verified against AlphaRes v1.1.0 on Windows 11 24H2 with Fortnite Chapter 7. CRU specifics (current build, supported Windows versions, EDID behaviour) reflect public information at time of writing from the maintainer’s project page on monitortests.com.
Two utilities sit at the top of every advanced thread when competitive Fortnite players ask how to drive a custom stretched resolution into Windows: AlphaRes and CRU (Custom Resolution Utility, by ToastyX). They look adjacent in the search results, the conversation often treats them as substitutes, and that framing causes new players to install the wrong one for their actual problem. The two tools operate at completely different layers of the stack. AlphaRes works inside Fortnite’s own configuration files at the game layer. CRU works on the EDID that the GPU driver reads from the monitor at the driver layer. The choice between them is not really a head-to-head shootout. It is a question of which layer of the stack actually contains the constraint the player is hitting.
This article walks through both tools across twelve practical aspects, then examines the risk profile difference (AlphaRes cannot damage your display setup, CRU can leave you on a black screen if you push a monitor out of spec), then covers when each is the right pick on its own and when the two are best stacked together. CRU is a powerful, legitimate tool with a long maintenance history. The framing throughout is right tool for the right scope, not AlphaRes is better. CRU wins on raw power. AlphaRes wins on safety and on Fortnite-specific lock persistence. For roughly ninety-five percent of competitive Fortnite players reaching for stretched resolution, AlphaRes alone is sufficient. CRU is reserved for the genuine edge cases.
TL;DR Verdict
- Different layers, different problems. AlphaRes operates at the game layer (writes Fortnite’s
GameUserSettings.iniand locks it via the read-only file attribute). CRU operates at the driver layer (modifies the EDID, the display’s own resolution table that the GPU driver reads at boot). - CRU is far more powerful but much riskier. CRU can add custom timings, override refresh rates, and define resolutions a panel never natively supported. Pushing a monitor out of spec can leave it on a black screen until you boot Safe Mode and run
reset-all.exe. - AlphaRes covers the typical Fortnite stretched-res use case with zero brick risk. It touches a single .ini file and flips one filesystem attribute. There is no display restart, no EDID override, no chance of a black screen at boot.
- CRU is the right pick only when AlphaRes cannot deliver what you need. Custom timings, exotic aspect ratios on panels that refuse them, refresh-rate overrides, EDID fixes for misreporting displays. None of this is needed for typical 1440×1080 or 1600×1080 Fortnite play.
- The combined stack is rare but legitimate. If a panel will not natively accept the resolution you want, use CRU to expose it to the OS and AlphaRes to lock it inside Fortnite. That covers the long tail of unusual setups.
What Each Tool Actually Does
Before any comparison table makes sense, the layer each tool operates on has to be clear. AlphaRes and CRU are not two implementations of the same idea. They are two tools sitting on different rungs of the Windows display stack, each one solving a different sub-problem.
AlphaRes (game layer)
AlphaRes writes width and height integers into Fortnite’s GameUserSettings.ini file at %LocalAppData%\FortniteGame\Saved\Config\WindowsClient, then flips the Windows read-only attribute on that file so Fortnite’s update process cannot rewrite it on the next patch. The scope is game-specific: the change only affects Fortnite, the values appear in the game’s own resolution logic, and no other application sees any difference. The operation is instant, fully reversible by clearing the attribute and deleting the file, and cannot affect display drivers or the monitor itself. The binary is 533 KB, MIT-licensed, and verified clean on VirusTotal across the full antivirus engine panel. Anti-cheat exposure is zero because nothing about the workflow touches the running Fortnite process or its modules.
CRU (driver layer)
CRU edits the Extended Display Identification Data, the EDID, that the GPU driver reads from the monitor over the display cable at boot. The EDID is the panel’s own table of resolutions and timings it claims to support. CRU lets you add, remove, or override entries in that table at the OS level, which makes the new resolutions visible to every application on the system, not just Fortnite. The scope is system-wide: Windows itself, every game, and the desktop compositor all see the modified resolution list. Applying a CRU change requires a display driver restart through the bundled restart64.exe utility, and a misconfigured timing entry can put the monitor into a state where it refuses the GPU’s signal at next boot. CRU has a reset-all.exe companion specifically for this recovery scenario.
The framing that makes everything below land correctly is this: AlphaRes is a Fortnite-specific tool that solves a Fortnite-specific persistence problem. CRU is a general-purpose tool that solves the broader problem of monitors and drivers not exposing the resolution the user wants. Both are useful, both are well-maintained, and neither replaces the other.
The 12-Aspect Comparison Table
The table compares both tools across the dimensions that actually matter for the Fortnite stretched-res decision. Rows where one tool wins outright tag the Winner column. Rows where both land in the same place are tagged as a tie. Where a CRU specific is not publicly verifiable as a hard number, the row says so rather than fabricating a value.
| # | Aspect | AlphaRes | CRU | Winner |
|---|---|---|---|---|
| 1 | Layer of operation | Game layer (Fortnite INI) | Driver layer (display EDID) | Different scopes |
| 2 | Game compatibility | Fortnite only | Every game and every Windows app | CRU |
| 3 | Lock persistence after Fortnite patch | Yes (read-only attribute) | No (driver-level, not Fortnite-aware) | AlphaRes |
| 4 | Display driver restart required | No | Yes (run restart64.exe) | AlphaRes |
| 5 | Risk of black screen at next boot | None | Possible if timings exceed panel spec | AlphaRes |
| 6 | Skill level required | Beginner (type W and H, click Apply) | Advanced (custom timings, CVT-RB, pixel clock) | AlphaRes |
| 7 | Custom refresh-rate / timing support | No (writes resolution only) | Yes (CVT, CVT-RB, manual timing) | CRU |
| 8 | Custom aspect ratio support on panels that refuse them | No | Yes (EDID override forces the panel) | CRU |
| 9 | Multi-monitor handling | Targets primary display, no driver-side conflict | Per-display EDID, easy to edit the wrong monitor | AlphaRes |
| 10 | License | MIT, fully open-source | Free, source unavailable per public information | AlphaRes |
| 11 | Last update / maintenance | v1.1.0 January 2025, actively maintained | Maintained by ToastyX, cadence reflects public information at time of writing | Tie |
| 12 | Chapter 7 verified for Fortnite stretched res | Verified working through 24-30 | Not Fortnite-aware, no Chapter-specific guarantee | AlphaRes |
The table reads cleanly: AlphaRes wins on the dimensions specific to Fortnite stretched res (lock persistence, no display restart, zero brick risk, beginner-friendly, Chapter 7 verified). CRU wins on the dimensions specific to general-purpose display capability (works everywhere, custom timings, exotic aspect ratios). Two ties (different layer scope, similar maintenance status). The one row that needs explicit unpacking is row five, the risk profile, and the next section is dedicated to it.
The Risk Profile Difference (the Headline)
The single most important point in the entire comparison sits in the column labelled risk. AlphaRes cannot damage a monitor or display setup, period. The tool reaches a single .ini file under the user’s local app data folder, writes integers into it, and flips the read-only attribute on the file. There is no path through that workflow that touches the GPU driver, the display cable, the monitor’s own firmware, or the EDID. The worst-case failure mode for AlphaRes is the resolution does not apply (Fortnite ignores the value, the file is locked at the wrong moment, the user typed an invalid width), and the recovery in every case is to delete GameUserSettings.ini and let Fortnite regenerate it. No display restart, no Safe Mode, no recovery from a black screen.
CRU sits at a fundamentally different risk tier. CRU edits the EDID, the panel’s own resolution and timings table that the GPU driver reads at boot. Entering an invalid timing, a refresh rate the panel firmware refuses, or a pixel clock that exceeds the GPU’s bandwidth can cause the monitor to drop the signal at the next display restart and stay black. The recovery is real but routine: boot Windows in Safe Mode (which loads a generic display driver that ignores the EDID overrides), run reset-all.exe to clear CRU’s modifications, reboot normally. The tool ships with that recovery utility precisely because the failure mode exists. Experienced display modders treat the recovery as routine. New users who hit a black screen at next boot read it as bricked hardware and lose confidence in the entire workflow.
Reading the AlphaRes safety story alongside the CRU one is not about declaring CRU dangerous. CRU is a power tool used safely by thousands of users, including monitor reviewers, modders, and OEM technicians. The honest framing is that CRU has a recoverable failure mode and AlphaRes does not have one, and that gap is the entire reason the brick-risk row in the table resolves the way it does. For Fortnite players whose only goal is a stretched resolution, the rational default is the tool with no recoverable failure mode at all. For users who already know how to navigate Safe Mode and have used CRU before, the gap closes considerably. The dedicated Is AlphaRes Safe? A 2026 Security Audit walks through the AlphaRes side of this story in full, including the VirusTotal scan that backs the zero-detection finding.
Setup Walkthrough: AlphaRes
The AlphaRes workflow is short by design. Total time from download to a working stretched resolution that survives the next Fortnite patch is under two minutes. The screenshots and the deeper walkthrough live in the dedicated How to Apply a Stretched Resolution in Fortnite Using AlphaRes guide; the four-step summary below is the minimum required to apply and lock a resolution.
Download AlphaRes
Grab the verified v1.1.0 binary from the AlphaRes download page. The file is 533 KB, single executable, no installer. Save it anywhere convenient (Desktop, USB stick, tools folder).
Launch and enter the resolution
Double-click alphares_x64.exe. Type the target Width (e.g. 1600) and Height (1080) into the two numeric fields. Optional: set FrameRateLimit and Window Mode. Close Fortnite first if it is currently running.
Tick Read-only and click Apply
Tick the Read-only checkbox. Click Apply. AlphaRes writes the values to GameUserSettings.ini, then flips the file’s read-only attribute. The window can be closed.
Launch Fortnite and verify
Launch Fortnite. The HUD and rendering target should be at the chosen stretched resolution from the lobby onward. The resolution will survive the next Fortnite patch automatically because the file is now read-only at the filesystem layer.
Setup Walkthrough: CRU
CRU’s workflow is more involved because the tool is operating on the panel’s own resolution table rather than a single text file inside one game. The five-step summary below covers the standard path for adding a custom resolution to the EDID. Specific dialog labels and section names match the long-standing CRU UI; this walkthrough is described in prose rather than with screenshots because no original CRU UI capture is included in this comparison.
Download CRU and extract
CRU is hosted on the maintainer’s project page on monitortests.com. Download the zip, extract to a folder you can find again (the recovery utility lives in the same folder and is needed if anything goes wrong). No installer; the bundle is portable.
Launch CRU and select the active monitor
Run CRU.exe. The top dropdown lists every connected display by EDID name. Select the monitor you actually play on. Editing the wrong one is the most common multi-monitor mistake and the one that produces the most confused reports.
Add the resolution under Detailed Resolutions
In the Detailed Resolutions section, click Add. Enter the target Width and Height (e.g. 1600 and 1080). Set the refresh rate. For the Timing field, pick Automatic (CVT-RB) on most modern panels: it produces a reduced-blanking timing that most LCDs accept without trouble.
Apply and run restart64.exe
Click OK to commit the change to the EDID, then close CRU. Run restart64.exe from the same folder. The display driver restarts (the screen blanks briefly), the new EDID is read, and the new resolution becomes available system-wide.
Verify in Windows Display settings
Open Settings, System, Display, then Advanced display, then Display adapter properties, and confirm the new resolution appears in the modes list. If anything looks wrong (no signal, scrambled output, the display refusing the signal at the next reboot), close everything and run reset-all.exe from the CRU folder. From Safe Mode if necessary.
The five-step CRU walkthrough is long for a reason. Every step has a rollback path, every step has a way to misclick, and the recovery is on the user. Compared with the four-step AlphaRes path, the difference in operational surface is the practical translation of the layer difference: AlphaRes is one tool touching one file, CRU is a tool reaching into the driver-level resolution table that every Windows process reads.
What CRU Does That AlphaRes Cannot
CRU’s actual unique value sits well outside the typical Fortnite stretched-res workflow, and that is the framing that puts the tool’s place on the map. The features below are real, useful, and entirely outside AlphaRes’s scope. AlphaRes is not even attempting to compete here.
The first is custom refresh rates. Forcing a 75Hz panel to 85Hz, an 144Hz panel to 165Hz on a margin the manufacturer left open, or a 60Hz desktop monitor to 75Hz with a CVT-RB timing that the panel happens to accept. Display modders run CRU specifically for this. AlphaRes only writes the resolution into Fortnite’s INI, with no path to the panel’s refresh-rate table.
The second is arbitrary aspect ratios on monitors that will not natively accept them. Some 1024×768 IPS panels, ultrawide setups behind USB-C dock chains that drop their EDID, and CRT monitors driven through HDMI-to-VGA converters all need the EDID forced before Windows is willing to expose the resolution at all. CRU is the canonical fix.
The third is EDID overrides for displays that report wrong native resolution. Cheap or older panels sometimes ship with EDID data that does not match what the panel can actually drive. CRU rewrites the EDID at the OS level so the GPU driver reads the corrected version.
The fourth is fixing scaling on USB-C dock chains and monitor adapters. Multi-monitor setups behind a single USB-C dock that aggregates EDID across displays sometimes need CRU to disambiguate which panel is which. AlphaRes has no role here at all.
None of these matter for the typical Fortnite stretched-res case where the player wants 1440×1080 or 1600×1080 on a panel that already supports those resolutions. They matter for the long tail of power users running CRT monitors, ultrawide-via-adapter setups, modded panels, or unusual dock configurations.
What AlphaRes Does That CRU Cannot
The reverse direction is just as decisive and far less commonly understood. CRU does not lock Fortnite’s resolution against patch-time rewrites. Even when CRU successfully gets a custom resolution into the OS-level resolution list (the EDID is updated, the resolution shows up in Windows display settings, every other game can pick it from a dropdown), Fortnite still resets to native after each patch unless something also locks the .ini file. CRU has no awareness of GameUserSettings.ini at all. Its job ends when the resolution is exposed to the OS.
This is the lock-persistence story that defines the entire AlphaRes value proposition. AlphaRes flips the read-only file attribute on Fortnite’s config, and NTFS refuses Fortnite’s update process the chance to overwrite the file at the filesystem layer. The resolution survives every patch automatically. The dedicated deep-dive on the read-only mechanism covers the exact attribute behaviour and why it survives Epic’s update logic.
The two tools can be used together, and the combined-stack section below walks through the specific scenario where this is necessary. For a player who already has 1600×1080 working on their panel through native EDID, AlphaRes alone is enough. CRU adds nothing because the resolution is already in the OS list. The instinct that more tools is more rigorous gets the choice backwards in this category. The right tool is the one that solves the actual constraint.
The Combined-Tool Stack: CRU + AlphaRes
Picture a player on a 1024×768 TN panel. The panel will not natively accept 1280×1080 because the EDID does not include that resolution. Running AlphaRes alone in this situation writes 1280×1080 into GameUserSettings.ini, but Fortnite’s resolution logic falls back to a supported mode at launch because the OS does not believe 1280×1080 is a valid panel resolution. AlphaRes is doing its job correctly; the problem is below it, in the EDID.
The fix is to run CRU first. Add 1280×1080 to the panel’s Detailed Resolutions list, apply through restart64.exe, and verify the new mode appears in Windows display settings. The panel and the GPU driver now both believe the resolution is supported. Run AlphaRes second to write 1280×1080 into Fortnite’s INI and flip the read-only attribute. Fortnite launches, picks up the resolution, and the read-only attribute survives the next patch automatically. Two tools, two layers, one working setup.
The combined stack is the only configuration where CRU is strictly necessary for a Fortnite-only goal. Every standard 16:9 panel running 1080p natively can drive 1440×1080, 1600×1080, and 1750×1080 through AlphaRes alone, because every standard 1080p panel exposes those modes through its native EDID without needing an override. The combined-stack case is real but rare, and a player who is not running a non-native or unusual panel does not need to consider it.
CRU Risk Warnings
Pixel clock above the GPU’s bandwidth (the GPU refuses the timing and the monitor receives nothing). Refresh rate the panel firmware refuses (the monitor accepts the EDID entry, then drops the signal at next display restart). Editing the wrong display in a multi-monitor setup (the override applies to a monitor the player is not actually using, and the working monitor stays unchanged while a different one breaks).
The recovery in every case is the same. Boot into Safe Mode (Windows loads a generic driver that ignores EDID overrides), run reset-all.exe from the CRU folder, reboot normally. Nothing is permanent. AlphaRes has no equivalent failure mode because the tool does not touch the EDID at all.
The point of the warning is not to scare users away from CRU. The point is to set the correct expectation: CRU is a power tool that occasionally requires Safe Mode recovery, and the user has to be willing to handle that recovery on their own. AlphaRes is the right default for users who do not want to handle that recovery, which is most users in the competitive Fortnite audience.
Verdict
AlphaRes is the right default for the Fortnite stretched-resolution use case. The tool covers ninety-five percent of the audience with zero brick risk, beginner-friendly setup, and lock persistence across Fortnite patches. CRU is reserved for the edge cases where the panel itself does not natively support the resolution the player wants, which is a small minority of setups. Both tools are well-maintained and legitimate; the choice is about scope, not quality.

FAQ
Is CRU better than AlphaRes for Fortnite stretched res?
For typical Fortnite stretched-res use, no. AlphaRes is the better default because it operates at the layer where the actual problem lives: Fortnite’s GameUserSettings.ini file getting rewritten on patch. CRU operates at the driver layer and has no awareness of Fortnite’s config file at all, which means a CRU-defined resolution gets exposed to the OS but Fortnite still resets after each patch unless something locks the INI separately. CRU genuinely beats AlphaRes only in scenarios where the panel itself will not natively accept the target resolution, which is rare on the standard 1080p monitors competitive players use. Even then, the right answer is to use both tools together (CRU to expose the resolution, AlphaRes to lock it inside Fortnite) rather than pick one or the other. For the ninety-five percent of players running 1440×1080 or 1600×1080 on panels that already support those modes, AlphaRes alone is the cleaner pick.
Will CRU get me banned in Fortnite?
There are no documented Easy Anti-Cheat conflicts with CRU. CRU operates on the EDID at the driver layer, which is below the application stack entirely; the tool does not load into the Fortnite process, does not hook DirectX or rendering APIs, does not modify game memory, and is not running while Fortnite is running because CRU’s effect is applied at the next display restart and persists until reset-all.exe is invoked. From EAC’s vantage point at runtime there is nothing to detect; the resolution list available to Windows simply has additional entries. Pro players and display modders have used CRU on the same systems where they play Fortnite for years with no observed ban pattern attributable to the tool. The same disclaimer that applies to AlphaRes applies here: download from the official source on monitortests.com rather than a rebundled mirror that might pair the binary with something else.
Can CRU damage my monitor?
Permanent hardware damage is extremely unlikely. Modern panels include firmware-side limits that refuse out-of-spec timings rather than physically driving them, which means the typical CRU misconfiguration produces a black screen or a loss-of-signal indicator, not a damaged backlight or panel. The risk profile is recoverable failure rather than permanent damage. The recovery is to boot into Safe Mode (which loads a generic display driver that bypasses the EDID overrides) and run reset-all.exe from the CRU folder. Older CRT monitors driven through HDMI-to-VGA converters historically had a more meaningful damage risk because CRTs lacked the firmware-side timing checks that LCDs have, but for any LCD panel made in the last fifteen years the risk is recoverable rather than catastrophic. The honest framing is that CRU has a routine recovery path for misconfiguration; AlphaRes has no equivalent failure mode at all because it does not touch the EDID.
Why does AlphaRes work for most players without needing CRU?
Standard 1080p monitors expose the resolutions Fortnite players actually want (1440×1080, 1600×1080, 1750×1080, 1920×1080) through their native EDID without any override needed. The GPU driver reads the EDID at boot, the resolution list includes those modes, and Fortnite is willing to render to any of them when GameUserSettings.ini requests one. AlphaRes only needs to write the right values into the right INI keys and lock the file. The driver-level path that CRU takes is unnecessary because nothing about the resolution is missing from the OS’s perspective. This is also why CRU is reserved for edge cases: the only situations where CRU’s contribution is needed are setups where the panel does not natively expose the target resolution at all, which is a small minority of competitive Fortnite hardware. For typical setups, AlphaRes alone removes the only constraint that exists.
Can I use AlphaRes and CRU together?
Yes, and this is the legitimate combined-stack workflow for the long tail of unusual setups. The two tools operate at different layers and do not conflict with each other: CRU writes EDID overrides at the driver layer, AlphaRes writes resolution values and a read-only attribute at the file layer inside Fortnite. The order matters: run CRU first to expose the new resolution to the OS (apply through restart64.exe, verify in Windows display settings), then run AlphaRes to write that resolution into Fortnite’s INI and tick the Read-only checkbox to lock it. The combined stack is the right answer for a player whose panel does not natively support the target resolution, which is the only Fortnite scenario where CRU’s contribution is strictly necessary. For standard panels that already expose the target resolution natively, the combined stack adds operational complexity with no benefit.
What is EDID and why does CRU edit it?
EDID stands for Extended Display Identification Data. It is a small block of bytes the monitor sends to the GPU over the display cable at boot, listing the panel’s manufacturer, model, supported resolutions, supported refresh rates, and supported timing standards. The GPU driver reads the EDID to build the list of valid display modes Windows offers in display settings. The OS treats the EDID as authoritative: a resolution that the EDID does not include is simply not available, even if the underlying panel could physically render it. CRU edits the EDID at the OS level (it does not actually rewrite the bytes inside the monitor; it intercepts the EDID the driver reads and substitutes a modified version). The result is the same as if the monitor itself reported the new resolution: Windows sees it, applications can pick it, the GPU drives it. This is the mechanism that lets CRU expose resolutions and refresh rates that the panel did not advertise on its own.
Will Fortnite patches affect a CRU custom resolution?
The CRU-defined resolution itself stays in the EDID across Fortnite patches because the EDID is not touched by Fortnite’s update process at all. The OS-level list of available modes is unchanged. What does get reset is Fortnite’s own choice from that list: when Epic’s update process rewrites GameUserSettings.ini on patch, Fortnite goes back to whatever its default-resolution logic considers right for the panel, which usually means native 1920×1080 rather than the player’s CRU-defined custom mode. The CRU resolution remains available in the resolution dropdown, but Fortnite has to be reconfigured to use it after each patch. This is the persistence gap that AlphaRes closes by flipping the read-only attribute on the INI file: the file cannot be rewritten, so Fortnite’s choice cannot be reset, so the player’s custom resolution stays selected across patches. CRU and AlphaRes solve different halves of the persistence problem on unusual panels.
Does CRU work on AMD GPUs?
Yes. CRU is GPU-vendor-agnostic because it operates on the EDID, which sits between the monitor and the driver regardless of who made the GPU. NVIDIA, AMD, and Intel cards all read the EDID at boot through the same Windows display infrastructure, and CRU’s overrides apply uniformly. There are occasional vendor-specific edge cases around how each driver handles certain EDID extension blocks (HDR metadata, FreeSync/G-Sync ranges, particular timing standards), but the basic add-a-custom-resolution workflow works on every modern desktop GPU. AlphaRes is also vendor-agnostic for the same structural reason: it writes into Fortnite’s INI rather than going through any GPU vendor’s control panel, so the choice between AlphaRes and CRU does not depend on the GPU brand on either side. A 7900 XTX user has the same set of options as a 4080 user.
Why does CRU need a display restart?
The EDID is read by the GPU driver at the start of each display session, not on every frame. Once the driver has the EDID parsed and cached, changes to the EDID overrides do not take effect until the next time the driver re-reads its source. The bundled restart64.exe utility forces the display driver to restart, which re-reads the EDID (now with CRU’s modifications applied) and rebuilds the list of available modes. The screen blanks for a moment during the restart, then comes back with the new resolution available. AlphaRes does not need anything analogous because Fortnite reads GameUserSettings.ini on game launch, not on driver session start: AlphaRes’s changes take effect the next time Fortnite is launched, and the file is read fresh each launch. The driver-restart requirement is one of the practical operational differences that makes CRU feel heavier than AlphaRes even when the underlying configuration change is similar in scope.
What is the safest CRU recovery if my screen goes black?
The standard recovery is Windows Safe Mode. Hold Shift while clicking Restart from the Start menu (or boot from recovery if Windows is not reachable), navigate to Troubleshoot, Advanced options, Startup Settings, then Enable Safe Mode. Safe Mode loads a generic display driver that ignores EDID overrides and produces a working signal at standard resolutions. Once Windows is up, navigate to the CRU folder (the one extracted from the original download) and run reset-all.exe to clear all CRU-applied overrides. Reboot normally. The screen comes back with the original EDID intact and the panel’s own resolution list restored. The recovery is routine for anyone who has done it before; the first time can be intimidating because a black screen at boot looks like a hardware problem. The presence of the recovery utility is the entire reason CRU’s risk profile is recoverable rather than catastrophic, and it is the reason experienced display modders treat CRU as a normal tool rather than a dangerous one.
Is CRU free?
Yes. CRU has been distributed free of charge since its initial release and remains free at time of writing. The maintainer (ToastyX) hosts the binary on monitortests.com without payment, registration, or ads on the download itself. The project’s release notes and version history are visible on the same page. Source code is not publicly distributed in the same way AlphaRes’s MIT-licensed source is, which is the one transparency dimension where AlphaRes is more verifiable for users who weigh that heavily. For the cost dimension specifically, both tools are free and neither has a paid tier, premium feature set, or advertising-supported install flow. The honest read is that the cost row in the comparison table is a tie, and the trust dimensions split based on how heavily a given user weighs source-code availability versus established maintainer reputation.
Should beginners install CRU?
For competitive Fortnite stretched-resolution goals specifically, no. Beginners who only need a stretched resolution that survives Fortnite patches should install AlphaRes and stop there. CRU is a power tool with a recoverable failure mode (Safe Mode plus reset-all.exe), and there is no benefit to taking on that operational complexity if the goal is a standard stretched resolution on a standard 1080p monitor. Beginners who specifically want to learn display-modding (custom refresh rates, EDID overrides, exotic aspect ratios for unusual hardware) are a different audience entirely, and CRU is the right entry point for that hobby. The framing that matters is not is the user a beginner, but is the constraint the user is hitting actually at the EDID layer. For the typical Fortnite stretched-res case, the answer is no, the constraint is at the Fortnite INI layer, and AlphaRes is the right tool. For the unusual-panel case, the answer is yes, and CRU plus AlphaRes together is the right tool.
