HP ThinPro 5.2 - Administrator Guide
HP True Graphics
HP True Graphics ooads rich multimedia content to the GPU, delivering high-frame-rate images and
boosting eciency.
HP True Graphics requires one of the following Citrix environments:
●
Citrix XenApp/XenDesktop 7 or newer
●
Citrix HDX 3D Pro (not running in Always Lossless mode)
HP True Graphics server-side requirements
XenApp/XenDesktop
The Citrix server must support sending session data in H.264 format. H.264 is enabled by default and is
processed using the DeepCompressionV2 encoder, a CPU-based compression algorithm.
Only full desktops or non-seamless applications are currently accelerated when using HP True Graphics.
Hosted remote applications running in seamless windows do not see benets from HP True Graphics. See HP
True Graphics client-side conguration on page 30 for information on how to force applications to run non-
seamlessly by conguring the TWI Mode setting on the thin client.
HDX 3D Pro
HDX 3D Pro desktops can use the H.264 format and benet from using HP True Graphics, even if running older
versions of XenDesktop. You might want to use HDX 3D Pro to ooad the server-side H.264 encoding to the
GPU using the DeepCompression encoder. See Citrix documentation for more information.
NOTE: HP True Graphics does not provide any performance enhancement if HDX 3D Pro is used with the
visual quality set to Always Lossless, because then the graphical information is not sent to the thin client in
H.264 format.
Verifying server compression options
After connecting to a Citrix desktop, use the Citrix HDX Monitor to determine which encoder is being used for
the session by examining the information under Graphics > Thinwire Advanced > Component_Encoder. If the
value reads DeepCompressionV2Encoder or DeepCompressionEncoder, then the server is properly sending
the data in a format that is accelerated by HP True Graphics.
NOTE: If legacy graphics are being forced via a server policy, such as CompatibilityEncoder or
LegacyEncoder, the server is compressing graphics in a method that is compatible with older versions of Citrix
clients and you will not experience enhanced performance from HP True Graphics.

Compression settings
H.264 compression must be enabled on the thin client for HP True Graphics to provide any benets. To enable
H.264 compression on the thin client, select the Enable H264 Compression checkbox in the Xen Connection
General Settings Manager.
Some screen data, such as text, might be sent using methods other than H.264. In general, it is best to keep
this feature enabled, but for troubleshooting or specic use cases, the following registry keys can be set to 0
to disable this feature:
●
root/ConnectionType/xen/general/enableTextTracking
●
root/ConnectionType/xen/general/enableSmallFrames
