Re: What driver version does 1080i properly?
To fix the overscan issue, try defining a modeline that only uses part of the full resolution. For example, construct a modeline that uses 1728x972 instead of 1920x1080. Such an approach should work with component out but probably not DVI or VGA.
To fix overscan for DVI or VGA you should use most of the same timings as the 1920x1080 modline, but just use the central part of the screen. Read about what each of the numbers in the modeline represent and it will become clear how to construct such a modeline.
