Why Is Part of My Screen Discolored or Tinted?

Discoloration — a yellow corner, pink band, or rainbow smear — has a handful of common culprits.

Step 1: Rule out the signal

Loose or failing cables cause tint and artifacts.

• Reseat both ends of the video cable; try a different cable and port.
• On laptops, gently flex the hinge area — if the tint changes, it's the internal display cable.

Step 2: Rule out software

• Disable color filters / night mode (Night Light, Night Shift).
• Reset any custom color profile (ICC) and GPU color settings.
• Update or roll back GPU drivers.

Step 3: Test the panel

Load full-screen colors with the Color Test and a White Screen:

• Uniform tint everywhere: likely color settings or color temperature.
• Localized patch: pressure damage or a panel/backlight fault.
• Rainbow/oil-slick smear: pressure on the panel layers.

Likely outcomes

• Cable/software → cheap or free fix.
• Localized physical discoloration that survives every test → panel issue, often a replacement.
