My 3090 video card was hooked to my Samsung q900r and when I switched on the HDMI 4-port in the input signal plus option I get a blank screen but I can still hear sound through the headphones. I unplug my HDMI port 4 from the one connect then plug it back in the port 4 again and my computer has kicked me out of Windows and I have to sign back in( and sometimes it doesn't kick me out of Windows). If I plug my 3090 through my Yamaha RX-V6A theater receiver everything works just fine at 4K60hz. I would really like to run 8k60hz directly through the TV but it looks like it's not going to happen and yes I have the latest 2.1 HDMI cables. Any suggestions?
