EDID for 1080p 50Hz

last week we were doing some EDID capture
and we noticed that the default Parrot 1080p50 EDID was wrong-
or rather it was different from image pros, matrix pros-

Parrot EDID timing was a 141.50MHz clock 2544x1144
screen refresh is 49.929Hz
Attachment 803

Image Pro/Matrix pro 148.50Mhz clock 2640x1125
screen refresh 50.000Hz
Attachment 804

49.929 is nowhere near 50.000

smpte timings from this page show image pro correct

any comments?

you might end up with different results depending upon the timing table
There are a few different timing tables used to generate the EDID settings:
GTF / CVT / SMPTE

Take a look in a Datapath X4 output timing page, or Lightware matrix advance EDID editor…
or Google 'edid timing tables'
see page 76 of the following publication:
ftp://ftp.cis.nctu.edu.tw/pub/csie/S.../EEDIDrAr2.pdf
and

...Dont get me started about CEA extensions HDMI and new MacPros!

the issue is the refresh rate timing - not the specific "GTF / CVT / SMPTE"

49.929HZ is not 50.000Hz - in a 25Hz/50Hz system
if you are mixing parrots cameras matrixes -
and parrots are giving you the wrong timing - default parrot settings need changing….

if you use a 49.929Hz refresh you will get glitching with almost every other type of video equipment
