Local dimming can make games look amazing — or it can create brightness pumping, crushed shadows, and instability that ruins readability. The goal is a stable setting you can keep, not the maximum contrast slider.

What Goes Wrong

  • Pumping: brightness changes during camera movement.
  • Crush: dark details disappear in HDR or dark scenes.
  • Flicker/instability: especially with VRR in dark content.

Tuning Order (Practical)

  1. Enable Game Mode and disable extra processing first.
  2. Set correct black level / RGB range (avoid false crush).
  3. Start local dimming at a medium setting.
  4. If pumping/crush appears, step down one level.
  5. Choose SDR for that title if HDR becomes unstable or unreadable.

Rule: stable readability beats maximum contrast. If local dimming ruins clarity, reduce it.
