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 configuration on server and agent desktop, see
VMware Certificate Guide at code.vmware.com/group/euc/thin-client/certs/4.6.
