I have the two panels, both bought here at spain...
The q17 (i have the dvi version) looks awesome for gaming, but have two problems... the view angles are worst than 171p and it has two brighter zones at the top and bottom of the screen noticiable in darkest colors and without natural light...
The samsung 171p has overall better image, but better colours... looks more accurate... (both with dvi) i think the q17 looks bluer...
so i have sold the 171p and i have now the q17 so i have the monitor for gaming and i dont need accurate colors...
The q17 is slighty wosrt but because i have a superb samsung panel... but the q17 is better than my ols sony crt.... uhhhh austanding
for those guys looking for the q17 dvi i have bought here
