DVI on Stratix II Audio Video Dev. Kit

After attempting to run the DVI loopback test many times, without successful result, I am wondering what I must be doing wrong.

I followed the configuration steps given in the .v file in the project, downloading via USB blaster to the FPGA, with a working DVI-D cable in a loop, and I get no output on the LEDs.

Am I missing an obvious configuration step? I am under the impression that when configuring via JTAG there is no need to alter the configuration DIP switches. I have all power levels enabled.

I am at a loss. Any help is appreciated.
