All my games resolution is stuck at 1920*1080 and My Laptop couldn't handle the graphics. I was able to lower my resolution in games before but when I turned my AMD to high performance it made all my games to run in 1920*1080 which lags the game and I cannot lower the graphics as no option is provided in resolution.
My laptop - HP 15 Ay503tx
AMD R5 m430
8 gb ddr4
Intel I5 6th gen
You can adjust the resolution via Windows Display Properties.
