You go see your eye doctor. Could be simple or serious.
I have been using a Plasma TV until I "upgraded" to a Samsung 46D7000 2 weeks ago. The picture quality and color are simply outstanding but I also noticed two problem areas:
1. Eye strain
2. There seems to be some "ghosting" perhaps due to a slow refresh rate? Could this be the cause for 1?
I have goggled as much as I can but have yet to find the "optimal settings" for this model. I guess I could call local Samsung support but I feel that they may not do much for a "fussy customer".
Hence I am turning to this Forum for help.
