That's what made me buy my first (and only so far) hd tv too At the time I said I could not be bothered getting a big thin tv to see tv in higher quality, but the xbox 360 games at the time weren't done full justice at all on a square analog tv. Let alone the ps4 games now It was an excellent investment :-D
As soon as I got a 1080P TV they went to 4K. I just want to watch Game of Thrones with the fancy color and they keep changing the rules!
