Did you read my post properly? I said that my first guess was the TV. But then, it works perfectly with AMD, and it works perfectly with Intel, but it doesn't work with Nvidia. Why do you think that is?
Why is it that Nvidia cannot be blamed for anything - any issue anyone ever has always has to be due to something else, just not Nvidia?

Whereas if I complain that the paint is chipping off of my chassis, (some) people just have a quick check of my system specs, and shoot
"bam, it's the bad AMD driver's fault".
