My PC is connected to my PC monitor (DisplayPort) and TV (HDMI). When I turn on my PC I get the MOBO splash screen on my PC monitor then it'll display a blank screen until I open my TV (second monitor). My PC monitor is set as my main display on the display settings. I've tried different combinations of DisplayPort cables and HDMI cables with the same result. Both displays are connected directly to my GPU.
