I have my PC connected to three displays: 2 monitors and 1 TV. The monitors are a Dell P2211H and an ASUS VS228. The TV is an LG web OS TV Model 43UM7300PUA.

The native resolution of the monitors is 1920 x 1080. The native resolution of the TV is 4096 x 2160.

I want to change my display resolution for my TV to 1920 x 1080 for better performance. However, I cannot do that. When I adjust the resolution for that display in Windows settings, it just switches back to 4096 x 2160.

That TV is connected to my graphics card via HDMI.

I am able to set the resolution to 1920 x 1080 through the menu in some games, however I want Windows to be at that resolution, as there are many games that don't let you change the resolution and just use whatever Windows is set to.

My graphics card is a Radeon RX 580.

My OS is Windows 10 Home 64-bit Build 19043.

How can I adjust the resolution for this TV to 1920 x 1080?
