i've been searching for a good tv/monitor for gaming and watch tv too (i'm using it as a tv and pc monitor ) but i don't know much about it .. i'll mainly use it for playing rpgs or fps at 1080p or higher if possible (my vga is a gtx 580) , i think the right size would be 42" what do you think ?is there a difference between a big monitor and a tv besides the tuner in it ? and what about those smart tvs ? are they good ? and what about 120hz , will i notice the difference ? what about lcd vs led ,which is better ? it must be cheaper than 900US$ .. thanks in advance
