color dynamic range test

Helps see if the setting of Color Dynamic Range (aka Output Dynamic Range, HDMI Dynamic Range) is mismatched between your GPU and monitor.

For best result, you should

• Turn off "Night Light" or "Night Shift" on your system, which reduces blue light at night.
• In graphics settings, if you can choose between RGB and YCBCR_42X, choose RGB.

Color dynamic range can be set to either "limited" or "full". Both your GPU and monitor could have this setting.

Scenario 1: if your GPU and monitor both have this setting:

• You should set both to full.

Scenario 2: if your GPU has this setting, but your monitor doesn't:

• Set your GPU to full, then look at this page.
• If you see 2 shades of whites and 2 shades of blacks, then your monitor is also full, you should leave it that way.
• If you see only 1 shade of white and 1 shade of black, then your monitor is limited. You should set your GPU to limited too.

Scenario 3: if your monitor has this setting, but GPU doesn't:

• Set to limited on monitor, then look at this page.
• If you see 2 shades of whites and 2 shades of blacks, then your GPU is also limited. You should continue to set monitor to limited.
• If you see only 1 shade of white and 1 shade of black, then your GPU is full. You should set your monitor to full too.
