Thread summary and practical next steps: described a monitor that is slowly losing correct colour. Replies from and point toward two broad causes: something upstream (video card, cable, drivers) or the monitor itself aging. The quickest way to make progress is a short, methodical isolation routine to determine which side is at fault and whether repair or replacement makes sense.

  • Observe the screen before the operating system loads (BIOS/UEFI or vendor splash). A persistent tint there usually rules out OS drivers.
  • Swap the video cable and the type of connection (VGA vs DVI/HDMI/DP). Try a different port on the PC or GPU.
  • Attach the monitor to a second known-good computer, and attach a known-good monitor to the original PC. That separates monitor vs GPU issues.
  • Use the monitor�s OSD to reset to factory defaults and run any built-in self-test (many LCDs show solid-colour patterns when no input is present).
  • Note whether the discolouration is uniform across the whole screen or limited to one area; uniform gradual tint points to backlight/power aging, local patches point to panel damage.

Why it happens and what to expect: modern LCDs shift colour as backlights age (LEDs can lose blue output faster, CCFLs dim and change spectrum). Power-supply components (aged capacitors or inverter circuits on CCFL sets) can also cause progressive tints or flicker. GPU/cable faults typically show channel loss, lines, or problems that follow the PC across different displays. CRTs are different—magnetization can be fixed with degauss.

Practical advice: if diagnostics show the monitor is the problem, weigh repair cost vs replacement; backlight or panel repairs are often not cost-effective on older consumer units. Do not open a monitor unless qualified—high voltages are dangerous. Record the model/serial and take photos when contacting support or buying parts.
