GPU
For high resolution displays, please ensure the GPUs used (both on the VDA and endpoint) meet the requirements for driving high-resolution displays. Refer to your GPU vendor's documentation for supported resolutions and refresh rates.
When using a server side GPU, Citrix® recommends the following minimal GPU frame buffer sizes:
| Monitors and resolution | Recommended Frame buffer size |
|---|---|
| 1 x 4K | 2GB |
| 4 x 1080p | 2GB |
| 2 x 4K | 4GB |
| 1 x 6K | 4GB |
| 1 x 8K | 8GB |
| 2 x 6K | 8GB |
| 4 x 4K | 8GB |
Note:
These are the minimum recommended frame buffer sizes for HDX™ Graphics Encoding. Please consult the application frame buffer requirements and factor these into your sizing as well.
Refer to the NVIDIA sizing guide for more information about Frame buffer sizing for NVDIA GPUs.
Refer to the Intel Virtual Desktop Infrastructure (VDI) Performance on Intel® Data Center GPU Flex Series Whitepaper for more information about GPU Sizing for Intel GPUs.
