Global Connection settings

1. On the desktop taskbar, click Connect Manager > Global Connection Settings.
   The Global Connection Settings dialog box is displayed.
2. Click the Session tab to configure the options that are available to all sessions.
   The Smart Card check box specifies the default setting for connecting to a smart card reader at system startup.

   NOTE:

   ICA sessions automatically connect when you connect the smart card readers. If you want to use the Disks option to automatically connect to ICA sessions, use the following guidelines:

   • More than one disk can be used simultaneously. However, the maximum number of USB drives including different subareas is 12.
   • Ensure that you save all data and sign off from the session before removing the USB drive.
   NOTE: USB devices redirection—By default, audio, video, and printer devices do not use HDX USB for redirection. You can make selections for USB device redirection on the Session tab of the Global Connection Settings dialog box.
3. Click the ICA tab, and do the following:
   1. Select the check boxes for the options that are available to all ICA sessions.
   2. Select an audio quality optimized for your connection.
   3. Use the Map to option to map a disk. When a drive is entered, the disk is mapped in the corresponding drive.
4. Click the RDP tab, and do the following:
   1. Select the Enable Network Level Authentication (NLA) check box if you want to verify users before connecting to a full RDP connection.
   2. Select the ForceSpan check box to span the session horizontally across two monitors. This option enables you to use two monitors as one large monitor.
   3. Select the Enable TSMM check box if you want to enable the Terminal Service Multimedia Redirection.
   4. Select the Record From Local check box if you want to enable recording from a local microphone.
   5. Select the RemoteFX check box to enable RemoteFX. RemoteFX is used to remotely deliver Windows virtual desktops over a network connection.
   6. From the USB Redirection Type, select RDP USB. To use RDP USB, you must use a RemoteFX session for Windows 7/Windows 2008 R2 session. However, RDP USB is not supported using a standard Windows 7/Windows 2008 R2 session. For Windows 8 session and later, RDP USB is supported.
   7. In the Desktop Scale Factor box, enter the DPI value in percentage. This option enables you to define the desktop DPI remotely. The Desktop Scale Factor is only applicable for the RDP connection. Setting this option does not impact the display scale of the thin client locally. The DPI range is 100–500. If you enter a nonnumeric character, the value is automatically set to 100. If you enter a value less than 100, the value is automatically set to 100. If you enter a value higher than 500, the value is automatically set to 500.
      NOTE: The desktop scale factor is applicable only to RDP version 8, and RDP 10 or higher versions. RDP version 7 is not supported.
5. Click the Horizon tab, and do the following:
   1. Select the Enable H264 check box. This option enables the H.264 decoding in Horizon Client. Enabling this option, improves the performance of high-end applications. H.264 is disabled by default. To validate the H.264 decoding, add an INI parameter setenv BlastDebugClientH264=yes, and verify if the H264 basic watermark is displayed in the upper-left corner of the VMware Blast session window.
      NOTE:

      • Blast H.264 feature is not supported on Wyse 5010 thin clients, Wyse 5040 thin clients, and Wyse 7010 thin clients. Blast H.264 is automatically disabled on Wyse 5060 thin client for 1920 x 1200 resolution due to hardware limitation.
      • A performance tracker is introduced by VMware for performance evaluation and data collection.
   2. From the Network Condition drop-down list, select whether to use a condition for your Blast connection.
      NOTE: Blast Extreme protocol is part of Blast Extreme Advanced Transport (BEAT).

      • Select Excellent to enable the Blast connection to use Transmission Control Protocol (TCP).
      • Select Typical to enable the Blast connection to use Transmission Control Protocol (TCP). By default, this value is selected.
      • Select Poor to enable the Blast connection to use User Datagram Protocol (UDP). UDP uses the available bandwidth to deliver the user experience.

        To enable UDP, you must modify the VMware View Connection Server, the Agent host desktop, and the VMware Horizon Client settings. For information about the necessary configuration on server and agent desktop, see the VMware Certificate Guide at code.vmware.com/group/euc/thin-client/certs/4.6.

   3. Select the High Color Accuracy check box. This option enables Horizon Client to use a superior color fidelity when H.264 decoding is enabled.
      The High Color Accuracy option is available on the following platforms:

      • Wyse 3040 thin client
      • Wyse 5060 thin client
      • Wyse 5070 thin client
