Why does the "Source signal on other port" message appear on my display?

This indicates that a video source connected to the Host does not correspond with the video port used on the PCoIP Zero Client. This can be corrected by either swapping the video ports used on the Host or the PCoIP Zero Client.

The following shows two host scenarios using VMware View virtual desktops or PCoIP Remote Workstation Cards for remote workstation applications.

Note: DVI marking varies on some PCoIP Zero Clients with some using the following. 

• DVI-0 (primary) and DVI-1 (secondary)  
• DVI-1 (primary) and DVI-2 (secondary)
• No specific DVI marking

Scenario 1:  VMware View 5.0 Virtual Desktops with a single display

When using VMware View 5.0 virtual desktops and PCoIP Zero Clients with a single display attached to the secondary zero client DVI port, the overlay message "Signal on other port" can be seen on the screen and you cannot connect to the session.  

Resolution:

This is resolved in VMware View 5.0.1.

Workaround:

This may be solved by connecting the DVI cable to the primary DVI port on the PCoIP Zero Client and reconnecting to the View 5.0 desktop. 

Scenario 2:  Remote Workstation using PCoIP Host Cards

In a workstation environment, when connecting a Tera2 PCoIP Zero Client to a single display, the "Source signal on other port" overlay message appears.

Example

If a single video source (GPU) is connected to a host card's primary port, and a single display is connected to a PCoIP Zero Client's secondary port, then the message Source signal on other port appears on the display.

Cause:

This error can be displayed when there is a mis-match with the cabling configuration between either of the following:

• • The PCoIP Remote Workstation Card and GPU.
  • The PCoIP Zero Client and the monitor.

In a workstation environment, display ports are matched "remotely" during a session with video signals from the PCoIP Remote Workstation Card and GPU. The primary port of the PCoIP Remote Workstation Card must match both the primary port of the PCoIP Zero Client and the primary port of the GPU. Similarly, the secondary port on the PCoIP Remote Workstation Card is matched to the secondary port on the GPU and PCoIP Zero Client and so on (when more than one port is used.)

Resolution:

Ensure the cables between the PCoIP Remote Workstation Card and gpu are connected to the same ports. Ensure the monitors in use are also connected to the PCoIP Zero Client display ports in the order in which they are intended to be used. 

For example,

The primary port on the PCoIP Remote Workstation Card connects to the primary port on the GPU and the primary monitor is connected to the primary PCoIP Zero Client port. The same for the secondary ports and so on.

Notes:

• • A zero clients primary port is the lowest numbered port on the zero client.
  • When connecting one monitor at 2560x1600 on a TERA2140 zero client (with four DVI ports), ports 1 and 3 must be teamed.
