I am in the market for a tv. I will eventually get a PS4 and like my first persion shooters. Right now I am considering the LG 47LA6200. I am really interested in the LG brand because of the passive 3D and Dual Play. I am looking at the 47 inch because it is for a bedroom (I had a 52 inch in my bedroom before and along with my pc the heat was too much), it's cheaper than a 55 inch, and I read somewhere that the pixel density on a 47 inch is better than a 55 inch and therefore results in a sharper picture. I have also read that the input lag on this tv in game mode is acceptable. Does anyone have any experience with this TV or other LG models? Is there another tv I should be considering? Should I spend a little more and get a 55 inch?
