Title:
omapdrm driver sets wrong resolution on HDMI/DVI
Status in linux-meta-ti-omap4 package in Ubuntu:
Won't Fix
Bug description:
I tested with two different DVI monitors, connected to the Pandaboard ES HDMI
connector using an HDMI-to-DVI cable.
On my 1600x1200 monitor, the driver always switches to 1400x1050 resolution
On my 1920x1080 monitor, the driver always switches to a resolution > 2000,
and the monitor blanks shortly after
However, <edid-decode
/sys/devices/platform/omapdrm.0/drm/card0/card0-HDMI-A-1/edid> shows
the correct information:
