The Graphics cards in a Genlock HD output one either 1 x DVI and 1 x Display Port (the FirePro 7800) or, 2 x Display Port connectors (FirePro 7900).

These Display Port cables are then adapted to DVI in order to go through the DVI Parrots.
The Display Port to DVI adapters limit the available resolution on each output to 1920 x 1200 pixels (DVI Single Link). This is caused by limitations of the DVI adapter. There are Display Port to Dual Link DVI converters on the market, however we have not found one robust enough yet to be installed permanently into a Hippotizer.
If you require resolutions higher than 1920 x 1200 from a Genlock HD, please bypass the Display Port Adapter and DVI Parrot by plugging straight into the Graphics Card.
