Summary0002134: Some HDMI resolutions like 1920x1080p-60 do not work
DescriptionWhen listing the possible HDMI modes in /sys/class/graphic/fb<x>/modes (use framebuffer for HDMI, usually fb0), it shows resolutions prefixed with "U:" and with "V:". Currently HDMI can only be used with the "V:" resolutions, the "U:" versions do not work.
Steps To Reproduceecho U:1920x1080p-60 > /sys/class/graphic/fb0/mode

will not show a picture. However the following command does:

echo V:1280x1024p-60 > /sys/class/graphic/fb0/mode
Additional InformationWhen trying to switch, the system gives warning that it cannot read EDID-Data from the display. Maybe the problem is the I2C for EDID.
