My computer CPU is the A10-5750M computer's graphics card is AMD Radeon HD 8650G (driver version 15.301.1901.0) +AMD Radeon HD 8790M (driver version 220.127.116.11).
But after updating the win10, all UWP video and game applications can not be full screen video clicking on the full screen. I searched all over the Internet, and there was no solution. I really don't know how to do it. The driver recommended by the official website can't solve the problem. The notebook manufacturer can't solve my problem. I want to give up the equipment to buy AMD in the future.
Please download DDU, it is a tool used to clean the AMD drivers.
Clean the driver you have installed actually, then either:
-Download and try to install this version please, 15.7.1 then let the Radeon settings update automatically: Legacy
-Download and reinstall the driver provided by the laptop manufacturer.
In your case the issue lie having your APU GPU needing very old legacy drivers, but your 8790M still support nowadays drivers.
Please let me know your laptop model, good luck and do not hesitate to ask if needed.
