HDR Ultimate
HDR Ultimate's game list: each game, the monitors it uses, and whether HDR turns on automatically or asks first.

Everything HDR, one tray icon

Per-monitor hotkeys

Toggle HDR on any one monitor, or a group of them, with a key combination or a click on the tray icon. The icon shows which monitors are on.

Automatic HDR for games

Add a game and HDR comes on when it starts, then goes back off when it closes. Have it ask first, or just do it. It reads the game's own HDR setting too.

OLED care

Tab out of a game and HDR switches off after a delay you choose, then comes back the moment you return. Less static brightness on screens that can burn in.

Resolution and refresh rate per game

Give a game its own resolution and refresh rate. Apply the resolution to the desktop while it runs, or write it into the game's settings.

Tiny and quiet

One small file, no installer and no background services. Light and dark themes that follow your system.

Windows and Linux

Built for Windows 10 and 11. A Linux version for KDE Plasma 6 and GNOME 48+ is in preview.

Edit HDR game
A game's settings: its monitors, what happens when it starts and closes, OLED care, and its resolution and refresh rate.

Set it up once per game

Pick the game's exe and its monitors. HDR Ultimate finds the game's settings file on its own and works out the rest.

A small prompt in the corner: Turn on HDR for Hogwarts Legacy? With Not now, Always for this game, and Turn on HDR buttons.

When a game asks first, a small prompt appears in the corner without taking focus from the game.

Install

Windows

  1. Download HDRUltimate.exe and run it. There's nothing to install.
  2. If Windows shows "Windows protected your PC", choose More info, then Run anyway. That appears for apps from small developers without a paid signing certificate.
  3. Find the icon in the system tray, and add your games in Settings.

Needs a monitor that supports HDR.
