The following post is an older nvidia article (from 2015) on monitor calibration:

The archived link from the nvidia article above has a set of images to help you review and adjust monitor calibration. The tests are subjective based on your eyes, monitor, and local lighting conditions.

Color Calibration (Linux Host)

Some settings will require restarting applications or logging out / in before the changes take effect.

NVIDIA

If you have an nvidia graphics card use the NVIDIA Settings package (nvidia-settings in apt)

  • X Server Display Configuration > [Display]
    • Resolution
    • Refresh > 60hz or more
    • other options...
  • OpenGL Settings > Image Settings > High Quality
  • Antialiasing Settings > Off
  • HDMI-(<dispaly-name>) > Controls
    • Color Space
    • Color Range
    • Dithering Controls > Auto
    • Digital Vibrance
    • Image Sharpening
  • HDMI-(<dispaly-name>) > Color Correction
    • Brightness
    • Contrast
    • Gamma

Integrated / CPU Graphics

If you have and nvidia card, or your system uses integrated graphics, use Settings > Displays to make configurations.

External Monitors

  • Check that each monitor is set to it's native resolution in the display settings
  • Check that HiDPI is enabled on your system
  • Turn off Fractional Scaling if it's enabled under Settings > Displays
  • Set each display to 100% Scale

From here you will need to check your external display's documentation.

The external display may automatically adjust defaults away from values you have previously set based on what device it thinks it's connected to.

In any case, review all of the external display's settings when troubleshooting.

One common issue is the external display will switch away from the 'HDR' mode (or it's brand equivalent) to a 'Game' mode. In this mode the display is blurry, contrast will be too strong, and color will be oversaturated.
