True Graphics client-side configuration on page 15 for information on how to force applications to run nonseamlessly by configuring the TWI Mode setting on the thin client. HDX 3D Pro HDX 3D Pro desktops can use the H.264 format and benefit from using HP True Graphics, even if running older versions of XenDesktop. You might want to use HDX 3D Pro to offload 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. HP True Graphics client-side configuration Compression settings H.264 compression must be enabled on the thin client for HP True Graphics to provide any benefits. 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 specific 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 Window settings Remote applications in seamless mode do not benefit from HP True Graphics. To force remote applications to be in windowed mode, set the TWI Mode option in the Xen Connection General Settings Manager to Force Seamless Off. Monitor layout and hardware limitations Note the following limitations on monitor layout: ● Most configurations with a maximum of two monitors at a 1920 ×1200 resolution each are supported. ● HP t420 Thin Client: Due to its default BIOS configuration, this product uses HP True Graphics for one monitor only, by default. See Enabling HP True Graphics for multiple monitors on the HP t420 on page 16 for more information. ● HP t730 Thin Client: This model supports a maximum of three monitors at 1920 × 1200. ● Rotated monitors might not display correctly.

True Graphics client-side
configuration
on page

for information on how to force applications to run non-
seamlessly by
configuring
the
TWI Mode
setting on the thin client.
HDX 3D Pro
HDX 3D Pro desktops can use the H.264 format and
benefit
from using HP True Graphics, even if running older
versions of XenDesktop. You might want to use HDX 3D Pro to
offload
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.
HP True Graphics client-side
configuration
Compression settings
H.264 compression must be enabled on the thin client for HP True Graphics to provide any
benefits.
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
specific
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
Window settings
Remote applications in seamless mode do not
benefit
from HP True Graphics. To force remote applications to
be in windowed mode, set the
TWI Mode
option in the Xen Connection General Settings Manager to
Force
Seamless
Off
.
Monitor layout and hardware limitations
Note the following limitations on monitor layout:
●
Most
configurations
with a maximum of two monitors at a 1920 ×1200 resolution each are supported.
●
HP t420 Thin Client: Due to its default BIOS
configuration,
this product uses HP True Graphics for one
monitor only, by default. See
Enabling HP True Graphics for multiple monitors on the HP t420
on page
16
for more information.
●
HP t730 Thin Client: This model supports a maximum of three monitors at 1920 × 1200.
●
Rotated monitors might not display correctly.
