8400GS overscan/underscan adjustment missing
I'm using an 8400GS outputting SDTV via s-video. Since it's just an old SDTV, I'm running 800x600 but 1024x768 looks no better. Basically, I have some massive overscan problems, ie the output from the card is about 10-15 % bigger than my TV will display. I've been searching here on on google for a solution but haven't found one. It seems as though the latest nvidia drivers don't offer over/under scan adjustment in nvidia-settings like the old 96xx series drivers did in back when I used an old 440MX that finally died. I've read about writing custom modelines to correct this but have yet to find a useful guide.
Does anyone have any thoughts?
