Table 4. Blast H.264 decoding

Screen resolution within VMware

Horizon Blast session

Blast H.264 decoding in VMware

Horizon Blast session

Summary

Session display width is less than or

equal to 1920 pixels.

Blast H.264 decoding is always enabled. Horizon client uses Blast H.264 decoding

even if the H.264 decoder setting is

disabled using GUI or INI options.

Session display width is greater than

1920 pixels.

Blast H.264 decoding is disabled by

default. You can enable Blast H.264

decoding either on the ThinOS GUI or by

deploying the INI parameter.

By default, Horizon client does not use

Blast H.264 decoding. If the Blast H.264

decoder setting is enabled on ThinOS,

then the Horizon client uses H.264

decoding. Enabling H.264 may

downgrade the session performance.

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.

b From the Network Condition drop-down list, select whether to use a condition for your Blast connection.

NOTE: Blast Extreme protocol is part of BEAT (Blast Extreme Advanced Transport).

• Select Excellent to allow the Blast connection to use Transmission Control Protocol (TCP).

• Select Typical to allow the Blast connection to use Transmission Control Protocol (TCP). By default, this value is selected.

• Select Poor to allow the Blast connection to use User Datagram Protocol (UDP). UDP uses the available bandwidth to

deliver the end-user experience.

To enable UDP, you need to make a few changes to the VMware View Connection Server, the Agent host desktop, and the

VMware Horizon Client. For information about the necessary conguration on server and agent desktop, see VMware

Certicate Guide at code.vmware.com/group/euc/thin-client/certs/4.6.
