I have an r9 390x and I was playing rocket league and randomly both my monitors turned black, but my computer was still on. My main monitor is a 4k UHD from LG and that's the one my display port is connected to. My other monitor is a benq 2430ti, which has a dvi cable connected to it. Whenever I have both my display port and any other cable connected to my graphics card my computer will shows the windows icon and the loading circle but then both monitors will go blank. This leads me to believe that my monitors and cables are working as the screen actually displays stuff. I tried my DVI cable on its own on my benq monitor and that works fine but I noticed it went black one time, when using a HDMI cable on my benq it works fine and have had no issues. But when my display port is connected to my other monitor by itself or with another monitor it goes blank. I also tested my integrated graphics with my display port and it worked to my surprise. Which leads me to believe it has something to do with my graphics card maybe my driver's. I did reinstall the previous version and it had no luck. I even swapped the pcie slot of my graphics card and it still had the same issue. I also reset windows as I heard it could've been a corrupted windows, I'm honestly out of options right now so any help is appreciated. Thanks
