How Do I Diagnose a Distorted Laptop Pink and Green Screen Artifact Issue?

[marcowayne]

Whenever I wake my PC from sleep mode, the entire monitor displays a corrupted laptop pink and green screen pattern. Moving the hinge back and forth sometimes restores the proper colors, but the discoloration eventually returns during heavy usage. Does this indicate a failing graphics processing chip, or is the internal video cable simply wearing out?

Try plugging your laptop into an external TV or monitor first! If the picture looks totally fine on the TV, your laptop screen or ribbon cable is busted, but if the TV is also pink and green, your graphics card is dying

To diagnose a laptop screen showing pink and green artifacts, first connect an external monitor. If the external display works normally, the issue is likely with the laptop screen or display cable. If artifacts appear on both screens, the graphics driver or GPU may be causing the problem. Updating drivers, checking cable connections, and running hardware diagnostics can help identify the exact cause.
