[QUOTE="incubusoccer"]OK... in HD there are 720 or 1080 lines of resolution in the pic. The Hz rating is how many times per second the television refreshes those lines. So on a standard HD, it will refresh ur pic 60 times per sec. 120Hz will give you smoother motion, but the 360 doesn't support 120Hz. The only way to do 120Hz is with a blu-ray that supports 24p = 24 fps. for good response time look at the sharp lcd's (4ms response) and the sony xbr's (4-5ms response, also the BEST lcd u can get at a resonable price.)primehunter326

Yeah I was also gonna point that out. The 360 can only render a maximum of 60 frames per second. The only time when refresh rate could be an issue is if you have a refresh rate that's lower than the framerate of the game, in which case you would get screen tearing. So while having a high (60+) refresh rate on the tv does make it faster, it won't affect the appearence of games because the 360 is locked at a maximum framrate.

Oh and Hertz and refresh rate are the same thing, hertz means cycles and in the casee of a display each cycle is one refresh of the screen so that it can display another image. Response time is the time it takes for the display the image it gets from the source. I'm just pointing this out because there seems to be some confusion here.

Actually HZ and refresh rate are completly different. refresh rate is how quickly the pixels on the TV can shift from black to white and back to black. So even at 60Hz, the refresh rate does matter. The lower the response time the less "ghosting" you will see on fast motion.
