Horizon Client supports the following multiple monitor configurations.
If you use two monitors, the monitors are not required to be in the same mode. For example, if you are using a laptop connected to an external monitor, the external monitor can be in portrait mode or landscape mode.
Monitors can be placed side by side, stacked two by two, or vertically stacked only if you are using two monitors and the total height is less than 4096 pixels.
To use the selective multiple-monitor feature, you must use the VMware Blast display protocol or the PCoIP display protocol. For more information, see Select Specific Monitors in a Multiple-Monitor Setup.
To use the vSGA 3D rendering feature, you must use the VMware Blast display protocol or the PCoIP display protocol. You can use up to two monitors, with a resolution of up to 1920 X 1200. For a resolution of 4K (3840 X 2160), only one monitor is supported.
For vGPU or other GPU passthrough modes, the vendor hardware and drivers determine the number of monitors and maximum resolution. For more information, see the NVIDIA GRID Virtual GPU User Guide, or go to the vendor website.
If you use instant clone desktop pools in Horizon 7 version 7.1 or earlier, the maximum number of monitors that you can use to display a remote desktop is two, with a resolution of up to 2560 X 1600.
With the VMware Blast display protocol or the PCoIP display protocol, a remote desktop screen resolution of 4K (3840 x 2160) is supported. The number of 4K displays that are supported depends on the hardware version of the desktop virtual machine and the Windows version.
Number of 4K Displays Supported
10 (ESXi 5.5.x compatible)
7, 8, 8.x, 10
11 (ESXi 6.0 compatible)
(3D rendering feature disabled and Windows Aero disabled)
(3D rendering feature enabled)
8, 8.x, 10
8, 8.x, 10
When the remote desktop screen resolution is set to 3840 x 2160 (4K), items on the screen might appear smaller, and you might not be able to use the Screen Resolution dialog box in the remote desktop to make text and other items larger. In this scenario, you can set the client machine's DPI to the proper setting and enable the DPI Synchronization feature to redirect the client machine's DPI setting to the remote desktop.
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 later installed in the remote desktop.
