I hope this is okay for me to post.
I had a 32" TV for 8 years and that's the TV I played Horizon on. Best Buy was having really good sales on TV's, so I upgraded to a 50" 4K HD TV and I feel like I'm playing a whole different game. The graphics are so much smoother and absolutely breathtaking.
I'm almost tempted to do a New Game+ just to experience it again (I'm on my 5th run, lol). I thought the graphics looked good on my small TV, but heck does it look freaking amazing on my new one...
