Vizio GV47L + Samsung 1080P7 problem

864 Views 0 Replies 1 Participant Last post by  kronowolf
Hi all,

I've tried searching for an answer to this problem for hours now and couldn't turn up anything that sounded exactly like the issue I'm having. Maybe someone can point me in the right direction.

I recently purchased a Vizio 47" GV47L 1080p HDTV and a Samsung DVD-1080P7 upconverting DVD player to go with it. I purchased an HDMI cable so that I could take full advantage of the Samsung's 1080p upconversion and the Vizio's 1080p output.

Here's the problem: at 1080p, when viewing video (or stills like the FBI warning placards from DVDs) that fills up the whole screen, there's a line about 4 pixels tall along the bottom that is misaligned with the rest of the image.

It's hard to explain and I don't have a way of screen capturing my TV, but it's as though something is bitshifting the tail end of the video out of alignment. If nothing draws near the bottom of the screen, there's no alignment corruption. But if video fills the whole TV screen, the bottom part is misaligned. It's the proper image, I'm certain of that, but it's been shifted so it doesn't line up with the rest of the image.

This only happens at 1080p. At 480p, 720p, and 1080i, the image is perfectly aligned.

I'm relatively new to the world of HDTV so I'm not sure if this has to do with overscan/underscan or some other common ailment suffered by HDTV adopters. Any guidance the community could offer would be greatly appreciated!
