I just filed taxes and I'm getting a measly $1100 back, but its enough to buy what a I want, a new HDTV. My friend has one and it has a handful of problems, the biggest one being a very noticable lag for platformers, especially Sonic and Mario. Those games happen to be a very big part of my gaming life, especially Sonic Generations, a game that came out the year his TV was manufactured. There is at least a 1 second delay with the controls. He has a 42" Vizio 120hz with a bunch of useless internet apps. I've done my research, but I can't seem to get a clear answer, what exactly do I have to avoid to get a TV without this atrocious lag? Is it the 120hz? Should I invest in 60hz instead? If you have a decently priced TV that works with older platformers as well as Sonic Generations and/or NSMB, please post your make and specs. I really don't want to buy an expensive TV just for it to be absolutely worthless with video games.
