Overlay pages are a way of displaying pertinent information to users during a PCoIP session. These pages occasionally overlay the user’s remote session.
Status overlay pages show network, USB device, and monitor statuses as icons and text. The overlays have simple animation and appear when the status changes (that is, the network connection is lost or an unauthorized USB device is plugged in).
Network Connection Lost overlay
Loss of network connectivity is indicated using an overlay with the message “Network connection lost” over the most recent screen data. This overlay appears when the client network cable is disconnected or when no PCoIP protocol traffic is received by the client for more than 2 seconds.
Figure 1. Network Connection Lost Overlay
The lost network connection message appears until the network is restored or the timeout expires (and the PCoIP session ends).
It is not recommended to use this notification message when using PCoIP devices with virtual desktops. Normal scheduling within the virtual desktop hypervisor can falsely trigger this message. For more information, see the Enable Peer Loss Overlay setting described in Vmware View Connection Configuration.
Preparing Desktop overlay
When you first log into a PCoIP session, an overlay appears with the message "Preparing desktop".

USB Device Not Authorized overlay
If an unauthorized USB device is connected, an overlay appears with the message “USB device not authorized.” The overlay appears for approximately 5 seconds.

USB Over Current Notice overlay
If the USB devices connected to the client cannot be handled by the USB ports, an overlay appears with the message “USB over current notice.” The overly appears until USB devices are removed to meet the current handling of the USB ports.

USB device not supported behind a high-speed hub overlay
Some USB devices cannot be connected through a high speed (USB 2.0) hub, and should instead be connected directly to the zero client or through a full speed (USB 1.1) hub. If such a device is connected to the zero client through a high speed hub, an overlay appears with the message “USB device not supported behind high speed hub”. This overlay lasts for approximately five seconds.

Resolution Not Supported overlay
If the resolution of a monitor connected to the client is not supported by the virtual machine, the monitor is set to its default resolution and an overlay appears with the message "Resolution not supported."
Figure 6. Resolution Not Supported overlay
PCoIP technology is not compatible with half-duplex network connections. When a half-duplex connection is detected, an overlay appears with the message “Half-duplex network connection.”
