Hello so I have a new pc with. 1080Ti. I have my main monitor plugged in to display port on my desk in the other room I have a hdmi running to a Yamaha avr. I use the windows and p command to switch between displays to use at my desk or at the tv. If I turn the receiver on then start my pc all is fine. But if I have my pc running then I turn on the receiver my main monitor goes black till I turn off the receiver or unplug the hdmi. This is so annoying does anyone know why this would be? It seems like it wasn’t doing this at one time but I can’t figure this out and I have searched everywhere!
