Here's how to fix it I am replying to my own post as I have found the solution.

I'm not sure if I should leave the driver Microsoft chooses dated 2015 (Video works) and try and fix the brightness problem, or install the Windows 8 version dated 2012 (brightness works) and try and fix the video problem.ĭriver Windows 10 Chooses (Video Works but can't adjust brightness)įai´l Report after installing Windows 8 Drivers (Brightness works but can't play videos) I can't find any other supported drivers for the AMD Raedon HD 6250M on the AMD support site. I installed the AMD install manager which installed new chipset drivers but that did not solve the problem with the brightness or the video. Reinstalling the AMD driver Windows 10 chooses allows me to play videos without any problem but then the brightness controls will not work. Again the brightness controls would work but the videos would not play or play with a lot of stuttering. Then from the Lenovo site, I downloaded and installed the Windows 7 Drivers in compatibility mode. I tried various video players and they opened and tried to play a video and suddenly auto closed. It installed AMD Catalyst control Centre and and then I could adjust the brightness. On the Lenovo support page I downloaded and installed a driver made for Windows 8ĭuring the install there was a fail warning that said it could not install the Display Driver. I can make the brightness indicator move up and down with the laptop function keys or from Windows settings, but this has no effect at all on the brightness. Everything was working fine except that I cannot adjust the screen brightness with the driver that Windows 10 has installed. I have fitted an ssd and upgraded my Lenovo G575 Laptop from Windows 7 64 bit to Windows 10 64 bit.
