I just recently installed a gigabyte gtx 960 into my system so I could use HDMI. I plug in my HDMI to my monitor and my background comes up but I dont see any programs and I only see the top of my taskbar. I right click to try and get into screen settings but nothing opens. I wasnt sure If i got a back GPU so I plugged my DVI output in and it works just fine so im a bit confused on what is wrong. I switched multiple HDMI cables as well and it was the same problem. All drivers are updated while DVI was plugged in and im not sure what else to do. Please help!
