We have the newer Panny ED plasma with several composite sources (LD, cable, VCR) switched through a receiver, and one component source (Denon DVD-1600). I wanted to ensure that the composite input was calibrated for the best PQ settings, so I added a composite cable from the DVD player to the receiver so I could switch the interlaced DVD output as well.
A strange thing happened when I started adjusting picture size/position. When I output the Video Essentials over-scanning test pattern on the component connection (interlaced or progressive), I get no image cropping (this is consistent with the hometheaterhifi shootout's results of the DVD-1600's pixel-cropping performance). However, when I switch the input on the plasma to composite, there is a bit of the image on the right side of the screen that is not displayed. I've tried adjusting the size of the screen using the panel's size/position settings to reclaim the lost portion of the test pattern, but the image itself simply isn't there to recover. Granted, the picture loss figures in at less than the 5% marker, but it's not symmetrical on both sides of the display. On the left side of the display, two hash marks are visible past the 5% line, on the right, there is only one--and since this player doesn't crop any of the image (at least on component), I can't figure out where the problem might be.
Has anyone else noticed this effect with the same DVD material sent to two different outputs? Is it possible the DVD player has different pixel-cropping performance depending on which output you use? I have also considered the Panny plasma handles its inputs differently so I've posted in the plasma forum, but I think there are probably more 1600 owners out there than Panny PDP owners, and I'd be curious to know if this behavior can be replicated on other types of displays. Since I don't watch DVDs via composite, DVD image size isn't that big a deal--color/tint/contrast/etc. were the settings I was really after--but now it seems like I might be missing part of my SD signals (slight though it may be). Anyone have some ideas of what might be going on?
Thanks
