Tool to fix Xiaomi G Pro 27i
I was one of the unlucky users who bought a flaky Xiaomi G Pro 27i with red tint and bad HDR EOTF. After a lot of frustration trying fixes online, finding guides that recommended tools that no longer work with Windows 11 on the latest NVIDIA drivers, I decided to create my own open-source tool to fix this monitor, called Color LUT Tweaks.
You can download it here: Release v0.2.0 · HugoSart/color-lut-tweaks
What the tool does:
- Allow applying LUT mapping to SDR and HDR modes separately.
- Allow doing color corrections separately in SDR and HDR (brightness, contrast, etc).
Because I created this to fix my Xiaomi monitor, this also includes a preset for this monitor. The preset does:
- Improve HDR EOTF curve; Image should look brighter on midtones.
- Map SDR to sRGB, so you can use the monitor in "Native" mode, eliminating the red-tint issue.
How to use it:
- On the monitor overlay settings, choose the "Native" Color Space; the tool will automatically convert to sRGB on SDR via software.
- Download and execute the tool
- Click on the system tray icon and select the Xiaomi preset under "Presets"; choose the one that you think is better
For the calibration, I used this article as a reference: https://chimolog.co/xiaomi-g-pro-27i/
I hope this saves you time and headaches. I spent countless hours trying to adjust this monitor. I hope Xiaomi learned from its mistakes.
