pixelation in HD

this problem is what has been keeping me from buying a new TV. Through all my browsing I noticed it on all LCD's and a slightly lesser extent on plasma's-in all price ranges. I have been told that this problem is only visible if you are sitting too close to the screen and is more apparent in the store. I'm glad someone mentioned having the problem in a home setting. I mostly watch sports, so it would drive me crazy to see constant pixelation during the action. Please let me know if you still see this effect (i heard it called the screen door effect) when sitting further away of if you find another solution. Thanks.
