Graveyard Keeper 2: How to Enable 32:9 Ultrawide Resolution

Ultrawide monitors wider than 2:1 aspect ratio are blocked in Graveyard Keeper 2, so 5120×1440 never shows up in the settings menu. This guide walks through a small open-source patcher that removes that filter and restores the missing resolutions.

 

Why 5120×1440 Does Not Appear

The game ships with a native configuration for 5120×1440 already built in. The problem is not missing resolution data. When Graveyard Keeper 2 builds its list of available display modes, it explicitly discards any resolution whose aspect ratio is wider than 2:1. Anything past that threshold is filtered out before it reaches the graphics menu.

The fix is a patcher that disables only that single ultrawide check inside Assembly-CSharp.dll. It does not inject custom resolutions and it does not ship modified game files. Before touching anything, the patcher backs up the original file and verifies the relevant game code matches what it expects.

 

Download

Grab the latest release from GitHub: GK2 Ultrawide Fix – GitHub Releases

Available builds:

• Windows x64
• Linux x64 / Steam Proton

The release binaries are self-contained. No .NET installation is required.

 

Installation and Usage

Windows

1. Download GK2-Ultrawide-Fix-win-x64.exe.
2. Run the executable. It automatically searches for your Graveyard Keeper 2 Steam installation.
3. Launch the game.
4. Open the graphics settings and pick your ultrawide resolution.

Linux / Steam Proton

1. Download GK2-Ultrawide-Fix-linux-x64 and mark it executable with chmod +x GK2-Ultrawide-Fix-linux-x64.
2. Run it with ./GK2-Ultrawide-Fix-linux-x64.

Both the main Steam installation and any additional Steam library folders are detected automatically on Linux.

Editor Warning: Close the game before running the patcher. Patching a DLL while the process is live can lock the file and cause the operation to fail. If your game feels choppy after a resolution change, check the usual stuttering issues before assuming the patch broke something.

 

Resolutions the Patch Unlocks

Only the wider-than-2:1 filter is removed. Every other limit in the game stays exactly as it was:

• Minimum width: 1280 pixels
• Minimum height: 720 pixels
• Maximum width: 5120 pixels

With the aspect ratio check disabled, these modes should be accepted, as long as your operating system and Unity report them as available:

Resolution	Aspect Ratio	Status
2560×1080	21:9	Expected to work
3440×1440	21:9	Personally tested
3840×1600	24:10	Expected to work
3840×1080	32:9	Expected to work
5120×1440	32:9	Personally tested
5120×2160	21:9	Expected to work

So far only 5120×1440 (32:9) has been verified by hand. The others are theoretical based on the removed filter and the remaining width and height caps.

 

Confirmed Test Results

The patch has been checked against the following setups:

• Resolutions: 3440×1440 and 5120×1440
• Aspect ratios: 21:9 and 32:9
• Platforms: Steam Linux / Proton and Windows 11

After patching, 5120×1440 appears normally in the in-game resolution list and works during play. The Windows build uses the identical patching mechanism, but it has not received the same level of testing as the Linux version.

 

What About 7680×2160?

A separate width limit of 5120 pixels still blocks super-ultrawide modes such as 7680×2160. Even with the ultrawide fix installed, these resolutions stay filtered out.

That cap can technically be removed the same way, but the option is not included yet. Testing resolutions past 5120 pixels wide needs hardware that is not on hand. If you run a 7680×2160 display, such as a dual-4K 32:9 monitor, and want support added, leave a comment. Enough interest will justify a future release.

 

Source Code and Safety Behavior

The patcher is open source under the MIT License. Source code, releases, and build instructions live on GitHub: GK2 Ultrawide Fix – GitHub

One design detail worth knowing: if a future Graveyard Keeper 2 update changes the relevant game code, the patcher aborts instead of blindly modifying an unknown version. That protects your installation from a corrupted DLL after a patch day.

Reports on other ultrawide modes such as 3440×1440 or 3840×1080 are welcome. If a resolution in this list fails on your setup, the details help improve the tool for everyone.
