Surface Pro 7 display brightness does not chage

Anonymous

Hi,

Anyone has the same issue as me?

When I change brightness with keyboard it does change to 30-50% only (no visible change).

When changing in side swipe, with touch it allows me to change 0%-100% (no visible change)

I tried with nigh mode off... no change

Tried windows setting ... no change

Ambient light On/Off... no change

Can anyone help?

Great fix, worked for me! Not sure of the origin of the low brightness/no adjustment issue however...would be good to know.

Hello, if you check the surface pro 7 update history, in the January 30th update there is one update that should have fixed the problems with display brightness. Please check that you have installed all the latest updates and if so, run the surface diagnostic toolkit to make sure no system files corruption are causing your issues.

Surface – System - 21.28.139.0	Surface Integration – System devices	21.28.139.0<br><br><ul><br><li><span>improves display brightness scenarios and improves integration between system services.</span></li></ul>
