Hi,

Well, it is possible, but not with the FPGA on carte blanche. The
Spartan 3E series cannot provide a transition minimized differential
signaling output to the monitor, which is what HDMI requires. Id also
have to either write or buy a DVI/HDMI parallel to serial video frame
formatter core, which either wont happen. The external chip is $7 and
is almost transparent, so a digital video interface can be realised
very easily with little logic required from the FPGA.
