I have Intel® UHD Graphics 620 "driver version 22.214.171.12473". I realized that after a while or after setting the PC to Sleep mode, the brightness control becomes very unresponsive "kind of not working properly". It's just sticking at a brightness level and never change. How to solve this problem?
I am using the one provided from Acer, downloaded it from their website. As I said many other friends have the same problem. Any suggestion? Maybe the driver has been updated by Windows Updates so, is there a way to downgrade it?
Thanks in advance!
Ok, you have an 8th gen processor. Now, you should use only the drivers provided by Acer. That said, you can try the latest/greatest DCH driver from Intel, which can be found here:
Make sure you have a backup. That said, probably nothing bad will happen.
I am on Windows 10 1903 Update. Months ago there was an issue where screen brightness did NOT change from battery to plugged in. They finally fixed that on an older version 1809 back in December. Is very similar to your issue. After a RECENT Update last week the ISSUE has returned. It appears that Windows and Intel know about it BUT no one seems to know IF and when they will fix it THIS TIME.
If you have windows REPORT your issue to Feedback Hub and maybe someone will do something
