Monitor Emulation

Teradici's monitor emulation feature for PCoIP Remote Workstation Cards presents a generic display to ensure the boot process completes. It is intended to alleviate issues related to graphics cards that do not enable Display Port or DVI ports when no monitor is detected and/or do not honor hot plug events. These issues can occur during initial BIOS/OS boot or at some time after a full OS boot.

Enabling monitor emulation will provide the motherboard/GPU BIOS, OS, and GPU software driver a valid EDID. In general, the firmware will respond with the last connected monitor EDID when monitor emulation is enabled. If no display has been connected to a port since the device was factory programmed, a default EDID is used. The default monitor definitions shown below.

Disable monitor emulation

This feature can be disabled to prevent GPUs from driving unwanted display outputs. When in session, the true hotplug/display state is only bridged from the client if the Remote Workstation Card Software is installed. This implies that a GPU may drive emulated ports with a video signal, even if the port on the client does not have an attached display.
