I'm using an LG 4K TV as monitor with an AMD PC using Windows 7. Graphics card is Radeon RX-460 and TV is connected with HDMI2 cable. The TV is reported as "Generic PNP monitor" in Device Manager. 4K resolution works fine when the PC is started from power off state. I've also set security so that sleep requires a login on awakening. But when it awakens, the login screen is not at full resolution and when desktop displays, all the windows have been snapped to the upper left corner in a tiny fraction of screen real estate. Needless to say, it's annoying to have to resize everything every time the PC sleeps!
I think the problem might be caused by the fact that when the video turns off before sleep, the LG TV changes its reported resolution to something much lower and this happens before the PC actually enters sleep state. Is there some driver I can use other than Generic PNP Monitor to prevent this? Some other fix?
