Problem with new Sharp LC-45GD4U

[Raypanic]

I just recieved this TV (LC-45GD4U) a month or so ago and just hooked it up in my new house. It is connected only to the Antenna on the roof.

Problem is while watching the Olympics in HD I get one or a few vertical lines on the right or left edge of the screen. If I use the picture alignment controls I can get rid of only one line at a time. If I move the screen left then the right line shows up and vice-versa. This is in Pixel x pixel mode. it only happens when viewing a HD (1080 I believe) brodcasts. One line is bright yellow where the other is blue. I looks as if the picture is not being expanded enough and these are margins that are normally out of view.

Any help would be great.

I have this also on my GX 45". I believe it's been discussed before. It's not the fault of the set, it's the network or local broadcaster not using enough overscan to mask these lines.

What happens when you take it out of the pixelXpixel mode?

99% chance the line is in the broadcast itself. Normally broadcasters assume TVs overscan 3-5% (basically overscan pushes edges of screen off the visible area) so they don't bother making sure the picture is perfect on the edges.

The reason you don't see it on most TVs is they don't support pixel perfect dot by dot mode, which Sharp is nice enough to provide (PC users and people who wish to disable stretching appreciate the feature)

You can tell the Sharp to do overscan like other TVs by changing the "View Mode" to "Stretch" from the current "Dot by Dot" mode.

Thanks for the replies. I use the dot by dot mode to get the best picture, I assume you loose something by using the s stretch mode?? Am I wrong? I cant really see much difference. I just thought you needed to run HD in a "Native mode"
