    My friend has an older RCA HD set, which only has DVI input, rather than HDMI. So, he has an HDMI cord out from the HR20-700 with an adapter on the end to convert it to DVI.

    He is having problems with his picture being off-set to the left about 5-10 percent and also blown up about 10%.

    It doesn't seem to annoy him much, but there's got to be a way to fix this for him.

    When viewing an HDTV channel, the guide and menu are both partially cut off on the left and bottom. I have the feeling that when viewing NFL games, graphics will be partially cut off too.

    Has anyone experienced anything like this with their sets? Is this a problem with converting from HDMI to DVI??

    I wonder, if he connects via component, does he see the same overscan?

    Those that have and been able to adjust it have done so by having the TV adjusted.
    Just about every TV has overscan and a service tech can make adjustments in the service menu to center & reduce the amount of overscan.

    Agreed, VOS. Personally I don't see why there's any overscan at all on HD flat panels.

    I have no problems using an HDMI to DVI cable. Maybe your friend could try a cable instead of a convertor.

    Also, does his TV have settings for Zoom that are enabled?

    He said that when he tried to hook up with component, it didn't display ANYTHING. Very strange.

    I looked through everything in the TV's menu system and couldn't find the ZOOM settings. There were buttons on the TV remote that had the ZOOM functions, but nothing happened when I pushed those.

    To clarify, his is actually a rear-projection HD unit. Don't know if that makes a difference.

    My HD RPTV had way too much overscan for me [in the order of 10+%] so I lost a lot of the image.
    Service menu is where adjustments are made, BUT be very careful as the wrong setting made there can cause the TV to not show a picture and then you can't "undo" the settings.

    If he turns off native mode and tries different resolutions, any help?

    I have the same problem on a 4 year old rear projection Mitsubishi. Same problem with DVI and component inputs. I haven't tried adjusting the overscan yet.

    What adapter is he using?

    I have an adapter setup on my plasma....

    There also may be a picture adjustment setting (I know there is on mine), that will allow me to shift the image over.

    Sounds like a problem with the TV itself....does he have any other sources to try the DVI input with?
