Many tvs are set up wrong, even at the store displaying them, it's crazy
alot of times the aspect ratio is set wrong to fill the screen because they are using something letterboxed as thier source in the store and don't want customers to see big black bars
every time I see a tv at a drs office or an older family members house I am astonished that they just turn it on and never set it up properly
refresh rate can make a huge difference as well big tv with slow rate looks wonky, the bigger it is the faster it should be
If you have the ability to do the install, there are kick ass projectors 1080p for less than $1200.00 that will make everyone who visits your house lose thier mind (including the cable guy), and will be so pretty to watch that you find yourself watching anything in full HD because you cant look away. Grab one on Amazon and ignore haters who complain about moire effects, I tried a vivtek and have never had anyone able to see a problem despite a few reviews that seemed horrible (any many good ones).
I did replace the bulb at 3876 hours after about 20 months (yeah we watch alot of TV on the 11' screen) {really 11 feet wide} sports in HD are the shiznit
