PCera, I need help. I’ve always run my Windows gaming PC through a TV via HDMI. Never had any problems, always plug and play. I’ve recently got my first ever 4K screen and my PC just wont work with it. It’s a Samsung NU8000 and when I plug the HDMI in I just get ‘no signal’ from the PC. Whether I boot the PC already plugged in to the TV or whether I switch the HDMI straight from a source where it’s working fine to the new TV. I’ve updated my graphics card drivers to the latest drivers.
