Menu path: Setup > Sessions > Citrix XenDesktop/XenApp > HDX/ICA Global > Options

In this area, you can set up additional options to optimize the system's general behavior and its performance.

  • Use Server Redraw

    The Citrix server is responsible for refreshing the screen contents.

    Do not use Server Redraw. (default)

  • Disable Windows Alert Sounds

    Switches off the Windows warning sounds.

    The warning sounds remain enabled. (default)

  • Allow Backing Store

    The X-Server temporarily stores hidden window content.

    Window content is not stored. (default)

  • Deferred screen update mode

    Enables delayed updates from the local video buffer on the screen. The local video buffer is used if the seamless Windows mode or HDX latency reduction is used.

    No delayed update. (default)

  • Cache Size in KB: (default: 1024)
  • Minimum Bitmap Size in Bytes: The minimum size of the bitmap files that are to be stored in the cache (default: 1024).
  • Persistent Cache Path: The directory in which the files are to be stored locally. (default: $ICAROOT/cache)

    Do not make the cache too big as otherwise you run the risk of the thin client having too little storage space for its own system and other applications. You may have no alternative but to equip your thin client with additional RAM.

  • Scrolling control: Depending on the speed of your network or the response time of your server, there may be a delay between your letting go of the mouse button on a scroll bar and the scrolling actually stopping (e.g. when using Excel). Changing this value may help (default: 100)
  • Audio Bandwidth Limit in StoreFront sessions
    • High
    • Medium
    • Low
    Higher quality requires more network and computing resources.
  • Enable Auto Reconnect

    Automatically attempt to reconnect if the connection is terminated. (default)

    Do not attempt to reconnect.

  • Maximum Retries: (default: 3)
  • Delay in seconds before reconnecting: (default: 30)
  • Allow Kerberos passthrough authentication in StoreFront sessions

    Kerberos passthrough authentication is allowed. (default)

    Kerberos passthrough authentication is not allowed.

    This point refers to Citrix XenApp in Version 6.5 and older.
  • CGP Address
    • use the server address
    • Text input
    • disabled
  • Multi-Stream ICA

    Support Multi-Stream ICA (Citrix Receiver 13.5 or newer). (default)

    Do not support Multi-Stream ICA.

  • HDX Adaptive Transport over EDT
    Possible options:
    • UDP without fallback to TCP
    • TCP only - UDP disabled
    • UDP with fallback to TCP
