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.

Monitors can be placed side by side, stacked 2 by 2, or vertically stacked only if you are using 2
monitors and the total height is less than 4096 pixels.

To use the 3D rendering feature, you must use the PCoIP display protocol. You can use up to 2
monitors, with a resolution of up to 1920 X 1200. For a resolution of 4K (3840 X 2160), only one monitor
is supported.

With Horizon Client 3.4 or earlier and 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.
n
With Horizon Client 3.5 and PCoIP, 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.
Hardware Version Windows Version
Number of 4K Displays
Supported
10 (ESXi 5.5.x compatible) 7, 8, 8.x, 10 1
11 (ESXi 6.0 compatible) 7 (3D rendering feature disabled; Windows Aero
disabled)
3
11 7 (3D rendering feature enabled) 1
11 8, 8.x, 10 1
NOTE 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.
n
If you use Microsoft RDP 7, the maximum number of monitors that you can use to display a remote
desktop is 16.
n
If you use Microsoft RDP display protocol, you must have Microsoft Remote Desktop Connection
(RDC) 6.0 or higher installed in the remote desktop.
Using One Monitor in a Multiple-Monitor Setup
If you have multiple monitors but want Horizon Client to use only one of them, after client installation, you
can select to have a desktop window launch in any mode other than All Monitors. By default, the window is
launched on the primary monitor.
