Bit of a long shot in trying to help me sort out a PC problem. I have a janky 3 monitor set up (technically two as one runs the audio) where my AV Reciever is running through the GPU's HDMI port, my main 49" curved Monitor is running from one of the DPs and the secondary monitor is running from DP number two. Issue is it runs fine until I switch off the the main monitor after gaming and it knocks off the second monitor and only works when I switch off the AV Reciever. I had brief look at Nvidia's control panel and it seems to be in the correct order. Scratch the thread I think solved the issue. I did manage to switch things about in Nvidia surround settings.
