display preference

okay. so you mean that even i shift from 1366*768(my native laptop resolution) to a full HD LED tv(1920*1080),my graphic card (HD5870M) is powerful enough to run decentely on a fully HD LED tv. but then what about the refresh rate ,i mean in my laptop its 60 whereas in the LED tv that i'm goin to buy its 120 hz i guess. can i tweak that setting to once i connect it from my laptop.
