Good question. We note that the EDID data wants these sync polarities.
Does the monitor use the pulse widths or the polarity to tell one mode
from another? We think that the polarity is used, but we are far from
certain.
Talking CVT here? as sync polarity there is used to flag H:V proportion.
What problem are you trying to solve? If any of your monitors does have
a problem requiring tight control over sync polarity, please provide a
log with the EDID block dumped.
I'm trying to set the i945G to 1280x768@60Hz mode. I've found that the
frequency is
52Hz and the syncs are wrong. But I do seem to have 1280x768 pixels.
Its not an EDID problem. In fact we are finding that we have to ignore
EDID a lot of
the time as its either (1) Missing a supported mode or (2) just wrong.
