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.
