How to interpret HorizontalActivePixel in EDID Standard Ti..

i already have a copy of EDID spec from VESA , when i use Phoenix's
EDID designer and EDID reader , for a 128 byte EDID 1.3 data set , it
interprets the standard timing and shows reoslution and refresh rate .
while for the same data , i can get the refresh data easily as it is
there , but am at a loss to understand how to come up with the
resolution from standard timing readings
what extra info , if any , is needed for that

thanks
Taha

OK - For the standard timings, you need to refer to the VESA Discrete
Monitor Timings
standard - standard and extended timings are "abbreviated" in the EDID and
are supposed
to be timings taken from the DMT standard (this is off the top of my
head...).
I seem to recall that the EDID standard does describe how to encode the
standard and
extended timings into those locations.<!-- ~MESSAGE_AFTER~ -->
