High resolution displays

Customers deploying high-resolution displays (6K, 8K, and equivalent megapixel counts) with Citrix Virtual Apps and Desktops, might experience issues with performance or issues such as mouse tracking inconsistencies and display scaling and DPI-related problems.

Traditional resolutions for typical office monitors are 4K, 6k or 8K resolutions where the ‘K’ notation is specifying the horizontal resolution.

Examples of 6K displays are the Apple Pro Display XDR and Dell UltraSharp U3224KB, with a resolution of 6016 × 3384, and 6144 × 3456.

Currently there are only a handful of 8K monitors available, one such example is the Dell UltraSharp UP3218K with a resolution of 7680 x 4320.

Barco lists their monitors with a MP or Megapixel count instead of their resolution. The newest Barco monitors are 32MP monitors with an advertised resolution of 6848 x 4560.

Citrix supports up to 8 monitors, depending on the hardware resources. Depending on the GPU used, there can be other hardware restrictions on this maximum.

To optimize performance and mitigate potential issues with high-resolution displays, Citrix recommends using CVAD 2402.

VDA versions 2402 and later

For VDA 2402 and later, leave the ‘Display Memory Limit’ policy to the default of 0, meaning no Display memory limit. This allows the VDA to dynamically allocate necessary display memory.

Older VDA Versions (Prior to 2402)

If upgrading to CVAD 2402 or later is not feasible, configure the “Display memory limit” policy to its maximum value of 4,194,303 KB. This provides the VDA with the maximum available display memory.
