Horizon Client supports the following multiple monitor configurations.

  • Horizon 7 version 7.8 adds support for six monitors at 2560 X 1600 resolution with virtual desktops that are running Windows 10 version 1703 or later. Updated Windows display specifications require Windows 10 version 1803 or later for six monitor support on Horizon 7 version 7.9 and later.
  • With instant clone desktop pools, the maximum number of monitors is four at 4K resolution.
  • 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 two or more 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.
  • With Hardware Version 13 or earlier, 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 to Display a Remote Desktop and Select Specific Monitors to Display Published Applications.
  • 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 are using five or more monitors, and you connect to a remote session with VMware Blast, if you use the same user credentials to connect to the session with PCoIP from a different device (without logging off the original session), the initial connection to the new session fails.

  • 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.

    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 and Windows Aero disabled)

    13 or 14 7, 8, 8.x, 10

    (3D rendering feature enabled)

    13 or 14 7, 8, 8.x, 10 4

    For the best performance, the virtual machine should have at least 2 GB of RAM and 2 vCPUs. This feature might require good network conditions, such as a bandwidth of 1000 Mbps with low network latency and a low package loss rate.

    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. 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 the Microsoft RDP display protocol, you must have Microsoft Remote Desktop Connection (RDC) 6.0 or later installed in the remote desktop.
