This isn't "what TV's do you have?" it's simply, what kind of TV (resolution wise) do you play games on? By the way, I'm sorry for just adding in 3D-TV. If you choose that, go ahead and just say if it's 720p or 1080p. I haven't really looked into it, but I'm guessing there really aren't any 720p only 3D televisions? My dad got one a while back and it said it was only 720p, but it runs everything in 1080p or higher. I think that's because of the size though.
I use a PC monitor, because I had one sitting around and it was cheaper to buy a VGA cable than to buy an HDTV. So far I'm extremely pleased with my monitor, because if I did not have it, I would not be able to have the set-up I currently do in my room. I can put it beside my laptop because the screen size is just about right to sit well with the two beside each other. It's an NEC AccuSync monitor of some nature, and I have no issues with it whatsoever.
Old ass standard definition t.v. I'm way behind the times man. Course, the nice thing about having two fat SD t.v.s is they don't need an entertainment stand, they can sit on top of each other, and I can change how my systems are hooked up to them on the fly, meaning when I have people over, people can play two different systems at the same time, or watch t.v. and play games, or what have you. I mean, yeah, it's pretty lame, but, I try to look on the bright side of having such shitty t.v.'s.
