I've decided I'm going to buy a hdtv mainly as a computer monitor(which i'll be playing games with) and secondly for tv. Here's the tv I plan on getting http://www.frys.com/product/6179429 which is on sale for $600. It has a pc input and everything. So my question is if I were to get a more expensive tv with 120hz or 240hz would it make a difference? From what I understand is that a computer cannot go past 60hz, or if it does it will cause input lag? Also how will playing games on on a tv look and feel? Does anyone have a setup like this that can tell me more about it? If you do not believe this TV is good for pc gaming please let me know.
