Also, at 37 or larger you really need to start investing in blu-ray DVD's since at this size regular DVD's do not view sharply - blu-ray is a 1080 format, regular DVD's are not.Picture quality is excellent from my Comcast HD cablebox and I have not had any problems with ghosting because it is only 60Hz - my preference is to use the 'Cinema' setting with a few slight adjustments.
