Analog output for newer models HD
Hippotizer HDs with a serial number 3751 or greater use 7700 series graphics cards. These cards have one DVI-I (DVI Integrated) and one DVI-D (DVI Digital) output each. The DVI-D connection, which corresponds to output two, does not contain an analogue signal. This means that adapters such as DVI to VGA or DVI to s-video will not work on this connection. If you require an analogue signal please use the DVI out labeled output 1.
The same is true for the Zookeeper card of Hippotizer HDs with serial numbers 3751 or greater: only Monitor 1 supports analogue output, Monitor 2 is digital only.
