I try to connect a HDMI screen to sabresd. Screen resolution is 1024x768 but board seems to be not reconize it. I try to show some pictures; All of them are incorrect in comparison to PC screen. I do this " cat /sys/class/graphics/fb0/mode" and get S:1280x720p-60. It seems that driver does not recognize this resolution. How can I add This resolution to driver?
