The message “No source signal” appears as an overlay at the start of a PCoIP session to indicate no video source.

There are three common causes for seeing this message in a host card environment:

• Cabling
  • To troubleshoot, first check the DVI connection between the GPU and the
    PCoIP host card. If the cable(s) appears to be connected properly,
    confirm that there is a video output by connecting the DVI port of a
    monitor directly to the GPU’s DVI output port. In order for this
    diagnostic step to be valid, you must not use any adapters (ie:
    DVI-to-VGA) between the GPU and monitor.
    Note: PCoIP host cards support DVI inputs only. They don’t support VGA
    inputs, but can support VGA signals through DVI-I connectors. While host
    cards support DVI input only, VGA can still be supported on the client.
    See client product specifications to determine if VGA output is
    supported.
    
• Software settings

  • This message may appear for a few minutes when the host PC/workstation
    OS turns off the monitor due to power management settings, screen saver
    timeout, or monitor shut down settings. The overlay appears shortly
    after the monitor is turned off and remains active for a couple minutes
    before it is eventually removed at which time the monitor is turned off.
    

• No OS installed on the host

  • This message will appear if there is no operating system installed on the host PC.
