Game "Brightness" Changes Randomly

4.5

The screen gets brighter and darker as you move around in the game, which is distracting.

Symptoms
  • Flickering brightness
  • Auto-dimming
  • Unstable contrast
Possible Causes
  • Dynamic Contrast on monitor
  • Windows "Auto-Brightness"
  • Local Dimming

Step-by-Step Fix

1

Disable "Dynamic Contrast"

In your monitor's physical menu, turn off "DCR" or "Dynamic Contrast".

2

Disable "Content Adaptive Brightness"

Windows Settings > Display > Brightness > Uncheck "Help improve battery by optimizing content".

3

Turn Off "Local Dimming"

If your monitor has zones, they can "pop" in and out, causing flickering.

When to See a Technician

Monitor "Eco" modes are the biggest culprit for annoying brightness shifts during gaming.
