    I just noticed something when I'm trying to do calibrations on my Tv with this DVD, it seems like the sides are cropped off and that was confirmed when I played the DVD on my computer and there was more on the sides than what was on my tv. Now I have a Panasonic 47wx53 and I'm using the Samsung HD931 so when I'm in 1080i mode I can't change the aspect (and its still cropped off) and in 480i mode even when I change to 4:3 mode the sides are cropped off...it became very noticeable on the color bar screen where the S in saturation is cut in half. I'm wondering if my screen needs adjusting via service menu, or it is normal for a full screen DVD like this?? Thanks for any help

    If you are using DVI connection try both "a" and "b" settings...

    It was on DVI setting B and I changed it to A and it made it a little better but not much. In fact, in the main menu where it shows the TV displaying Sound and Vision etc. half of the tv is cropped off!! I tried changing the DVD setup from widescreen to letter box(I figured it woudln't work) no such luck...I'm wondering how I can check another DVD to see if its ok, I have Gangs of New York and it seemed ok, but I'm not sure.

    Thanks,

    Andy

    It's normal for CRT-based TVs to have some overscan. 5% (on each side) is to be expected. You can probably verify the amount of overscan w/ an overscan test pattern from the S&V disc. If it's >5%, then you might want to reduce it to 5% via the service menu. If you reduce it much below 5%, you'll introduce difficult geometry problems.

    RE: the 4x3 mode, it's kinda odd, but apparently, Panasonic adds a lot of "artificial" overscan along those grey side bars. On my 53wx42 (last year's model), I get ~7% overscan from the grey side bars, and there seems to be no way to reduce that, except to use aspect ratio control on the source device instead -- I rarely use the TV's 4x3 mode anyway as I defer to the DVD player or set-top box instead since I don't like the rather bright grey side bars.
