Using PCoIP® Zero Clients with PCoIP Host Cards

6.2 Client Does Not Display Desktop – “Source Signal on Other Port”
When using the client with a single monitor (or with a single PCoIP integrated monitor), it is possible for the
video signal to be sent to the video output with no monitor. When this happens, the easiest solution is to
reverse the connectors connecting the graphics card to the PCoIP host card or to connect the monitor to the
other DVI output on the client (if you are using a client connected to a separate monitor). Another alternative is
to remap (swap) the monitors in the host operating system.
Note that some graphics cards must be connected when they boot or they do not provide video output. If you
connected or switched the video connector cables after booting the host PC, you may have to restart the host
PC after connecting the video cables to restore video.
6.3 Temporal Dithering
Temporal dithering is a technique used by some graphics cards that can cause excessive bandwidth utilization
during PCoIP remote sessions. See Section 3.7 for details.
7 Audio
Zero clients use the Realtek High-Definition Audio Codec. Windows 7 and Vista natively contain an HD
Audio driver for this Codec. For other operating systems, including Windows XP, download and install the
High-Definition (HD) Audio Codec driver from http://www.realtek.com to use the PCoIP system’s full audio
capabilities.
