dwm_eotf_rs SERGEYDJUM

Use this command to install dwm_eotf_rs:

winget install --id=SERGEYDJUM.dwmEOTFrs -e

dwm_eotf_rs is a utility designed to correct SDR-to-HDR color conversions in Windows by patching shaders within the dwmcore.dll module. This tool serves as an enhanced alternative to its predecessor, offering improved reliability and additional functionality.

Key Features:

System tray controls for easy toggling of shader patches
Autostart capability via Task Scheduler for seamless operation
Shader dumping feature for research purposes
Compatibility mode for simplified console usage
More reliable performance compared to previous versions

Audience & Benefit:
Ideal for Windows users experiencing incorrect color reproduction in HDR content. It provides a user-friendly solution to ensure accurate display calibration, eliminating the need for multiple attempts or manual intervention. The tool is particularly beneficial for gamers and professionals requiring precise color accuracy.

This software can be installed via winget, ensuring straightforward setup for end-users.

About

An alternative implementation of the same idea that is behind dwm_eotf.

It has additional features, such as system tray controls, autostart and shader dumping. This version is also more reliable, as it does not require multiple tries for it to work (as far as I can tell).

dwm_eotf_rs works by reading memory of the loaded dwmcore.dll module, patching shaders that are responsible for incorrect SDR to HDR conversions there and writing it back.

You do not need to revert the patch or restart DWM when playing HDR games or videos. It only affects DWM composed SDR content!

Usage

Help Output

Patches DWM's shaders to use proper EOTF (gamma)

Usage: dwm_eotf_rs.exe [OPTIONS] [GAMMA] [COMMAND]

Commands:
  restore         Restores original sRGB EOTF (by restarting DWM)
  schedule        Creates a task ('dwm_eotf_rs') that runs the app with default options on user logon
  unschedule      Removes the startup task ('dwm_eotf_rs') from Task Scheduler
  unschedule-all  Removes the startup task ('dwm_eotf_rs') from Task Scheduler for all users
  dump            Dumps DWM's original shaders as DXBC
  help            Print this message or the help of the given subcommand(s)

Arguments:
  [GAMMA]  Exponent to use during EOTF patching [default: 2.2]

Options:
  -c, --compatibility-mode     Patches DWM and exits (disables tray mode)
  -s, --skip-patching          Prevents automatic patching on app start (tray mode)
  -w, --wait-time   Delay (in seconds) before automatic patching on app start (tray mode) [default: 5]
  -i, --ignore-whitelist       Patch every shader that contains sRGB EOTF patterns
  -h, --help                   Print help
  -V, --version                Print version

Tray Mode

By default, the app runs in system tray, where you can toggle patch as needed as well as select gamma value (2.0/2.2/2.4/[GAMMA]).

When it launches, it will wait a few seconds before inital patching, supposedly to help with crashes.

Compatibility Mode

This mode turns dwm_eotf_rs into a simple console app - it patches DWM and exits.

Startup

dwm_eotf_rs can register itself to run automatically in when user logs in, using the Windows Task Scheduler (task named ).
