According DMT spec, vss of this mode should be 1393, vse should
be 1396.
VESA MONITOR TIMING STANDARD:
Timing Name = 1856 x 1392 @ 75Hz
Hor Total Time = 8.889; (usec) = 320 chars = 2560 Pixels
Hor Sync Start = 6.889; (usec) = 248 chars = 1984 Pixels
H Back Porch = 1.222; (usec) = 44 chars = 352 Pixels
Ver Total Time = 13.333; (msec) = 1500 lines HT – (1.06xHA)
Ver Sync Start = 12.382; (msec) = 1393 lines
V Back Porch = 0.924; (msec) = 104 lines

Please prefix the subject with "drm/edid: " and send the patch to
dri-devel@lists.freedesktop.org.
In general, scripts/get_maintainer.pl will tell you where to send the
patches; intel-gfx is for stuff under drivers/gpu/drm/i915.
Thanks,
Jani.

That is indeed what the spec says. However to review this I wrote a
quick awk script to parse the spec, and that shows a few more
differences. I'll toss out a patch with the results of my script...
