How to Get the Desired Desktop Resolution and Configure Multi-Monitor in Case of HDX 3D Pro Enabled Desktop in XenDesktop 5.5

This article describes how to get the desired desktop resolution and configure Multi-monitor in case of HDX 3D Pro enabled Desktop in XenDesktop 5.5.

Supported Desktop Resolution with HDX 3D Pro in XenDesktop 5.5

  • While connecting the client requests desktop with certain size (resolution ex. 1920×1200), which should be supported by the GPU on server (VDA) and by the monitor attached to the VDA. If there is no monitor attached on VDA, then it should be present in the set of resolutions supported by the GPU. If the matching resolution is found, then the desktop with that resolution is given, else the desktop with the nearest supported resolution is given.
  • In some cases the use case might require a specific desktop resolution, for example 1440×900, which is not available at the VDA side then it can be added as a custom resolution in the GPU control panel on VDA. If the GPU on the VDA accepts this custom resolution then it is available for the next connection.
  • When users try to connect from any tablets, the screen resolution of the tablet should be known. Once the resolution is identified, they must check on the VDA side to see if it is available. If the resolution is not available, then add a custom resolution in the GPU control panel on VDA.
  • Changing the desktop resolution within the session is not supported. If the resolution change is required then following procedure should be used:
  • If the desktop is in full screen mode then change the client local screen resolution, disconnect and reconnect.
  • If the desktop is in windowed mode then resize the desktop window to the desired size, disconnect and reconnect to get the desired desktop resolution.

Multi-Monitor Configuration

  • It is important to note that for HDX 3D Pro in multi-monitor case, the following condition should be satisfied:
    Number of Monitors on VDA >= No of monitors on client
    So, for dual monitor desktop, VDA should have two or more monitors attached.
    These monitors can be physical or virtual. The virtual monitors can be configured in NVIDIA control panel for Quadro and Quadro FX cards using forced Extended Display Identification Data (EDID) option.
  • On first connection, the desktop might be displayed in the single monitor mode only. To get true multi-monitor desktop, move the desktop window across 2 monitors on client and maximize the desktop using desktop viewer toolbar at the top so that it spans across two monitors. Now disconnect and reconnect the desktop. On reconnect, the desktop displays in true multi-monitor mode.
