I'm connecting my ThinkPad W510 to my Panasonic TV with DisplayPort to HDMI port. The image on the TV is missing a part or picture around the screen. On my notebook, the gauges in the top right are displayed correctly, but they are cropped on the TV display - some sort of misconfigured resolution perhaps?
Here is a view of the picture on the TV. See how part of the gauge is outside the viewable area?
This appears to be a typical TV overscan issue. Many televisions have overscan adjustment or a 1:1 pixel mode or a "just scan" mode. In this particular case on this Panasonic, the follow menu configurations were found to resolve the effect:
"Menu" - "Setup" - "Picture Overscan"
This option was setup as "On", and when switched to "Off" the picture is now correctly displayed.
