Hi Kevin,

A correction for my comments above, I can see when VGA port is used, the
Xserver can go into desktop and X log shows everything is working fine. For
HDMI, it can do mode setting correctly only enter into command mode instead of
graphics mode and X log shows it still probing VGA edid information which is
not correct.
If you have time to give a try on closed driver, let's see what happens at your
side, especially for DP port and HDMI port.
By the way, you should use a old kernel, i.e., 3.1.10 to compile the closed
driver for VX900 which is a requirement for that driver.

Thanks,
Frank
