HDMI Output in Black & White

I connected my Dell laptop to my TV via HDMI and the picture on the TV was in Gray scale instead of Color. I had connected my laptop before and it worked fine so I knew that my TV and the HDMI cable were working correctly. I had recently updated the drivers for my NVIDIA […]
