binary edid obtained with read-edid (complained about extra blocks)

Since introduction of DP audio in 4.0 all the way to 4.10 monitor does not sync unless mode <=1920x1080 is used or radeon module is loaded with audio=0.

Tried modes 1920x1200 (nearest supported larger mode) and 2560x1440 (native).
