Supported Multiple Monitor Configurations on Horizon Windows Client

Omnissa Horizon Client supports the following multiple monitor configurations.

• Omnissa Horizon 8 supports all standard multi-monitor configurations available to the client, such as stacked, side-by-side, landscape, and portrait modes, as well as mixed combinations. For example, if you are using a laptop connected to an external monitor, the external monitor can use either portrait mode or landscape mode. Nested mode is also supported for multi-monitor configurations.
• With the Omnissa Horizon Blast display protocol, six monitors up to 4K (3840 x 2160) are supported on Windows 10 and Windows 11 agent machines.
• With the Horizon Blast display protocol, two monitors up to 8K (7680 x 4320) are supported on Windows 10 and Windows 11 agent machines. This topology is supported only with Horizon Client for Windows.
• You must allocate sufficient memory and CPU system resources in the virtual machine to support the requested topology. For best performance, the virtual machine should have a minimum of 4 GB of RAM and 2 vCPUs. The multiple monitor feature might also require good network conditions, such as a bandwidth of 1000 Mbps with low network latency and a low package loss rate.
• With instant clone desktop pools, the maximum number of monitors is four at 4K resolution.
• To use the selective multiple-monitor feature, you must use the Horizon Blast display protocol or the PCoIP display protocol. For more information, see Select Specific Monitors to Display a Remote Desktop on Horizon Windows Client and Select Specific Monitors to Display Published Applications on Horizon Windows Client.
• For vGPU or other GPU pass-through 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 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.

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 activate the DPI Synchronization feature to redirect the client machine's DPI setting to the remote desktop.
