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 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 To force remote applications to run in windowed mode: ▲ Set the TWI Mode general setting for Citrix connections to Force Seamless Off. Monitor layout and hardware limitations Consider the following limitations on monitor layout: ● Most configurations with a maximum of two monitors that have a 1920 × 1200 resolution are supported. ● HP t420 Thin Client: Due to its default BIOS configuration, 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 Buffer 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 configured via HPDM or via the BIOS tools included with HP ThinPro. Client-side configuration 37

Monitor layout and hardware limitations

Consider the following limitations on monitor layout:

●

Most

conﬁgurations

with a maximum of two monitors that have a 1920 × 1200 resolution are

supported.

●

HP t420 Thin Client: Due to its default BIOS

conﬁguration,

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

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:

Restart the thin client and press

F10

to access the BIOS.

Select

Set

Set

UMA Frame

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

conﬁgured

via HPDM or via the BIOS tools included with HP ThinPro.
