So... to sum it up. I have this tv for quiet some time now... and well. Yes, first day i was quiet annoyed by input(shouldn't it be output?) lag. I couldn't see it... but i've felt that there is something wrong with the mouse. Like it's lagging behind. Samsung are known for having v.good black colour, BUT there is quiet a lot of processing going on behind the screen so input lag is also one of the highest on the market. Colours are definitely better than on my both 17" LCDs, and using it as a monitor(sitting around 1-1,5 meter away) was comfortable after one day
(i had a slight headache on the first day
). In LFS it is brilliant... well... in any other game it is brilliant
... but in T/FPS games(Mass Effect, Armed Assault 2, Call of Juarez) there is a hardly noticeable lag, you can use to it after a while. 60HZ is not a problem, well.. it's definitely enough.
