Try the following steps to correct the red/incorrect colors on the monitor:
- Update graphics/display drivers
- Open Settings > Update & Security > Windows Update and install all available updates.
- If the PC is from a specific manufacturer (for example, Lenovo, Dell, HP), also check the manufacturer’s support site for the latest graphics (WDDM) driver and install it.
- Check HDR and color issues
- If the monitor is HDR-capable and HDR is turned on, incorrect color or color fringes can appear.
- Make sure the latest graphics drivers are installed as above.
- If using HDMI and the monitor supports DisplayPort with HDR, connect with DisplayPort instead of HDMI.
- If HDMI is the only option, try:
- Lower refresh rate:
- Go to Settings > System > Display > Advanced display.
- Under Choose a refresh rate, select 30 Hz (if available).
- Or lower resolution:
- Go to Settings > System > Display > Advanced display, then select Display adapter properties.
- On the Adapter tab, select List All Modes.
- Choose 1920 by 1080, 60 Hertz, then select OK.
- Check Night light (if the screen looks warm/red overall)
- Go to Settings > System > Display > Night light settings.
- If Night light is on, either:
- Drag the Strength slider to the left to reduce the red tint, or
- Select Turn off now to disable Night light.
- Use sRGB color profile if skin tones or reds look exaggerated
- Go to Settings > System > Display > Color profile.
- For the affected display, change the color profile from Vivid or Enhanced to sRGB.
- Enable automatic color management (for more accurate colors on supported displays)
- Go to Settings > System > Display > Color profile.
- Select the display, then turn on Automatically manage color for apps.
If the problem started exactly after moving the PC and monitor, also reseat or replace the video cable (HDMI/DisplayPort) and ensure it is firmly connected at both ends, as a loose or damaged cable can cause color shifts.
