Regardless of the display protocol, you can use multiple monitors with a remote desktop.
If you use PCoIP, the display protocol from VMware, you can adjust the display resolution and rotation separately for each monitor. PCoIP allows a true multiple-monitor session rather than a span mode session.
A span mode remote session is actually a single-monitor session. The monitors must be the same size and resolution, and the monitor layout must fit within a bounding box. If you maximize an application window, the window spans across all monitors. Microsoft RDP 6 uses span mode.
In a true multiple-monitor session, monitors can have different resolutions and sizes, and a monitor can be pivoted. If you maximize an application window, the window expands to the full screen of only the monitor that contains it.
This feature has the following limitations:
If you use PCoIP, the maximum number of monitors that you can use to display a remote desktop is 4, with a resolution of up to 2560 X 1600 if you have enough video RAM. The maximum number of monitors that can be stacked vertically is 2. If you use more than 2 monitors, the monitors must be in the same mode and have the same screen resolution. That is, if you use 3 monitors, all 3 monitors must be in either portrait mode or landscape mode and must use the same screen resolution.
To use the 3D rendering feature, you can use up to 2 monitors, with a resolution of up to 1920 X 1200. You must use the PCoIP display protocol.
If you use Microsoft RDP 7, the maximum number of monitors that you can use to display a remote desktop is 16.
If you use Microsoft RDP display protocol, you must have Microsoft Remote Desktop Connection (RDC) 6.0 or higher installed in the remote desktop.
