My PC is hooked up to a 1440p 144hz monitor via Displayport. And a 4k 60 hz TV through an audio receiver via HDMI. I play games on both about equally, just depends on whether I want to sit at a desk or not. But whenever I try to switch from one to the other, it won't launch in the correct resolution, usually it will launch in something like 640x360. And in the settings menu, it won't even let me select the correct resolution. Even though Windows is running in the correct resolution. And even if I disable the other monitor, it will generally take me a reboot (or two) before it will display correctly. I am not really sure what to do to make this a smoother transition from one screen to the other.
