The monitor has a Backlight Response setting with three options: 'Gaming', 'Desktop' and 'Hybrid'. 'Gaming' makes the local dimming react almost instantly when the monitor's screen changes; 'Desktop' makes the monitor react to changes with a very slow fade (~5 seconds), and prioritizes maintaining bright parts of the screen rather than making adjacent dark areas darker; this makes the local dimming less distracting for desktop use. 'Hybrid' is a blend of the 'Gaming' and 'Desktop' behaviors. We recommend setting Backlight Response to 'Gaming' to start, then if you find the local dimming distracting you can select 'Hybrid', then 'Desktop' as needed.

Local dimming is available in SDR as well as HDR. In SDR, the SDR Variable Backlight option must be enabled. In SDR the peak brightness is limited to 300 cd/m², so the impact of local dimming is less noticeable.
