Notes:
1. Each switch represents 2 possible configuration choices.
2. Each frame buffer output can be routed through the mux to any of the outputs.
3. Each frame buffer has its own resolution, color depth, and refresh rate.
4. TMDS alone is in DVI-D format, and TMDS+Audio is in HDMI format.
5. RS690E offers dual DVI by utilizing both TMDS outputs from the LVTM interface and the TMDS interface multiplexed on the
PCI-E graphics lanes.
