Go through the following steps:

 

·         Power cycle your host PC/workstation if you encounter this issue.

·         Make sure the graphics card’s DVI output is connected to the Host Card at the host PC/workstation. Note: The Host Card is not compatible with VGA output.

·         Make sure a PCoIP session is connected.

·         Make sure the DVI cables are firmly connected on the Host Card and Zero Client.

·         Make sure that a DVI cable is connected between the graphics card’s DVI port that is driving video signals and the Host Card’s DVI port.

·         Make sure the monitors support the PCoIP supported resolution.

·         Make sure the proper graphics card driver is installed.

·         Make sure the default video output option in your BIOS is properly configured. Most BIOS lets you choose PCIe, VGA, or AUTO as default.

·         Make sure your desired displays are enabled in display properties of your OS. (For example, right-click in Desktop > Properties > Settings > Extend my Windows desktop onto this monitor) For example, if you have on-board VGA and a DVI graphics card in your host PC/workstation, and video outputs only from your VGA but not DVI port, you can connect a monitor to your host PC/workstation using a VGA cable and then enable the monitors connected to your Zero Client by enabling them in display properties of your OS.

·         Make sure that the Host Software Driver PCoIP Agent Settings - Monitors and ensure that the Use client topology settings when starting a session or resizing the software client window is enabled. Disconnect and reconnect the session for the updated setting to take effect.
