HP ThinPro 7.0 - Administrator Guide

NOTE: 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 specic 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
To force remote applications to run in windowed mode:
▲ Set the TWI Mode general setting for Citrix connections to Force Seamless O.
Monitor layout and hardware limitations
Consider the following limitations on monitor layout:
● Most congurations with a maximum of two monitors that have a 1920 × 1200 resolution are
supported.
● HP t420 Thin Client: Due to its default BIOS conguration, this model uses HP True Graphics for one
monitor only, by default. See Enabling HP True Graphics for multiple monitors on the HP t420
on page 37 for more information.
● HP t630 Thin Client: This model supports a maximum of two monitors at 1920 × 1200 or one monitor at
3840 × 2160.
● HP t730 Thin Client: This model supports a maximum of three monitors at 1920 × 1200.
● Rotated monitors might not display correctly.
● If you are using HP True Graphics with two monitors and trying to play a video using HDX MediaStream,
the video will fail because H.264 supports only two hardware decode sessions, which are being
consumed by the monitors.
NOTE: HDX MediaStream is also trying to leverage local hardware decoding of H.264, which causes the
issue.
Enabling HP True Graphics for multiple monitors on the HP t420
To enable HP True Graphics for multiple monitors on the HP t420:
1. Restart the thin client and press F10 to access the BIOS.
2. Select Advanced ► Integrated Graphics.
3. Set Integrated Graphics to Force.
4. Set UMA Frame Buer Size to 512 MB.
After these steps are performed, the amount of memory available for graphics is expanded, and HP True
Graphics can be used for two monitors.
TIP: These settings can also be congured via HPDM or via the BIOS tools included with HP ThinPro.
