I am having a weird issue with Windows 10 and an old laptop with a Radeon Mobility HD 4850 graphics card.
When running on the Microsoft Generic Display Adapter drivers (IE, no drivers installed) Everything works fine other than the display won't sleep and I can't change from the native resolution (I don't want to so not a big deal). However, as soon as I install the AMD drivers for the card, my screen goes black but with the backlight still on. I have tried multiple versions of the drivers with the same result.
Some Interesting things when this happens:
What is going on here? Why do graphics drivers break Windows ability to properly detect and drive the built in display?
me and along with my friend are facing the same issue mate and sadly there is no solution or fix for it yet
