I got my 73738 last week. I am getting really bad pin cusion when using my vista HDMI PC, when looking at pictures both left and right side of pics are bowing inward, also noticed pin cusion on regular TV viewing but its really noticable on PC viewing pictures etc. Is there and adjustments to correct this? Also my stand from my previous TV is 22 in high and I sit about 10 ft, can really notice top of screen gets dimmer when line of site is lower than center screen, when I slowly stand and get my eye to center screen the top gets brighter. This would not be a problem with at least 12ft or more. Its really bad if I am tired and lay down on couch. Will have to build another stand, 17 inch high sounds about right. For a temporary fix a have put a 1/2 inch strip of wood under the rear of the TV making the top lean forward, this helps alot, it simulates an center screen with a 17in stand. Any ideas on geometry problems?? Really hate to return TV for pin cusion. Other than that picture is great.
