I just recently built a new mythbox using Ubuntu 9.10, an nVidia 9600GT graphics card that is connected via DVI->HDMI to a Toshiba 50HM67 50in DLP. I have read other posts where overscan is an issue with certain rear project HDTV's. It would appear that mine has the overscan issue as well.
I have tried different resolutions with the nvidia card but the top/bottom and sides are cut off on the screen by about 5% on screen. Has anyone been able to solve this issue and if so, what did you do to correct it?
Any help would be greatly appreciated!
