There just doesn't seem to be anyting else comparable that wouldn't have a similar issue, so If I can't live with it I'll do without in my theater room for awhile.
That's pretty much what I'm thinking... I'm really trying to learn to live with the horizontal line, but it's hard and every time I see it, I feel like my heart skips a beat and I get kinda stressed this will get worse.
I've run my grey and green slides on three different HX701. Mine has this line and pillaring on the right side, one had pillaring on the right side and dark areas all around the edge of the screen and the other one had pillaring, dark areas and like 4-5 horizontal lines.
Since my pillaring is very light and unnoticeable unless I look directly at the right side of the screen, that leaves me with the line, which unfortunately is directly at the height where we look at most of the time.
My GF says she doesn't see it, so I think I'm a big part of the problem. I feel like I've got some kind of obsessive compulsive disorder when I shop for a tv! This pisses me off so much that sometimes I feel like giving up on TV and invest all that money in books!
