Because in a perfect world, a video card will push to TV just fine regardless if it's NVIDIA or AMD. No need to do a specific review on that capability, as a functioning monitor, cable, and video card will all perform relatively identically.
If you're here just to troll bait NVIDIA fans instead of actually addressing the problem with your product (i.e. bad cable/bad port on the TV end/bad port on the video card), let me know so you can stop wasting the "goddamn time" of people who are actually trying to help you. Because instead of just accepting the possibility that you might have been unlucky enough to get a bad card, or that there might be SOMETHING ELSE wrong and trying any of my suggestions and giving feedback for more help, you came back here just to bash on a brand.
Bad cards happen *just* as often on the AMD side as well, arguably slightly more often if you look up some manufacturer's RMA rates. *Everyone* gets unlucky sometimes. I've had bad AMD cards and bad NVIDIA cards a plenty. When you're ready to keep trying to diagnose your problem/return your card, let someone know.
