Okay, please do not attach anything other than what is really necessary if you
want the developer to help you figure out why your display is not working.
You should have disclosed that you were using a KVM switch since I have no
control over the equipment you have.
I got burned 2 years ago when someone I was helping out was using a faulty SD
Card to PATA reader even though the code was already fixed.

Again, there is currently no support for VX900 chipset's integrated TMDS
transmitter that handles HDMI.
If the HDMI display is displaying anything this is because VGA BIOS set the
registers up, but OpenChrome DDX currently does not have the code to control
them.
