Yesterday I was trying to make the colours on my screen look brighter so I turned on the HDR colour setting, adjusted it, realized it wasn't going to brighten up the colours then disabled it again. Then when I turned on my laptop this morning I tried to turn down the brightness and it won't adjust at all.

I tried manually locating and updating drivers, adjusting it in the power settings, adjusting from the Graphics Properties menu, reset my laptop, messed with the nightlight. Then I tried to go back and try adjusting the HDR settings again and the little slider disappeared! I even have a game on steam (Car Mechanic Simulator 2018) that saves it own brightness setting and will override what ever I had it set to normally, and it STILL won't change!


I'd rather not reinstall Windows and I've already done a full reinstall twice ( the first of which needed to be done because I downloaded some nostalgic gamecube games) and one repair install since I bought this computer one year ago.
