User manual

You can mirror the entire device display on a projector or attached monitor, including the Unity Touch
sidebar, by turning off the Presentation Mode setting. If you are connected to a remote desktop and the
Presentation Mode setting is turned on, you can click Done to switch to mirror mode.
Use the Keep the screen alive during Presentation setting to keep the display from turning off after a
period of inactivity while in presentation mode.
PCoIP Client-Side Image Cache
PCoIP client-side image caching stores image content on the client to avoid retransmission. This feature
reduces bandwidth usage.
The PCoIP image cache captures spatial, as well as temporal, redundancy. For example, when you scroll
down through a PDF document, new content appears from the bottom of the window and the oldest content
disappears from the top of the window. All the other content remains constant and moves upward. The
PCoIP image cache is capable of detecting this spatial and temporal redundancy.
Because during scrolling, the display information sent to the client device is primarily a sequence of cache
indices, using the image cache saves a significant amount of bandwidth. This efficient scrolling has benefits
both on the LAN and over the WAN.
n
On the LAN, where bandwidth is relatively unconstrained, using client-side image caching delivers
significant bandwidth savings.
n
Over the WAN, to stay within the available bandwidth constraints, scrolling performance would be
degraded without client-side caching. Over the WAN, client-side caching saves bandwidth and ensure
a smooth, highly responsive scrolling experience.
With client-side caching, the client stores portions of the display that were previously transmitted. The cache
size is one-half of the available RAM. If that amount of RAM is less than 50MB, the cache size is 50MB.
Suppress the Cellular Data Warning Message
When Horizon Client detects that you are using a cellular data connection, the Network Usage dialog box
appears to notify you that your remote desktop or application connection might use a substantial portion of
your data plan.
In Horizon Client 3.1 and later, the Network Usage dialog box appears after you connect to a View server
and try to launch a remote desktop or application, after you tap a recent desktop or application shortcut,
and after you connect to a remote application and try to launch another application or remote desktop from
the Unity Touch sidebar. In Horizon Client 3.2 and later, the Network Usage dialog box appears only when
you launch Horizon Client.
In Horizon Client 3.1 and later, you can suppress the Network Usage dialog box after it appears. You can
also set an option to always suppress the Network Usage dialog box.
Procedure
n
To suppress the Network Usage dialog box after it appears in Horizon Client 3.1 and later, tap Don't
show this message again in the Network Usage dialog box.
n
To suppress the Network Usage dialog box after it appears in Horizon Client 3.2 and later, tap Never
Remind in the Network Usage dialog box.
n
To set an option to always suppress the Network Usage dialog box, use the Horizon Client user
interface tools to display the Options list and toggle the Cellular Data Warning option to Off.
Internationalization
Both the user interface and the documentation are available in English, Japanese, French, German,
Simplified Chinese, Traditional Chinese, and Korean. You can also input characters for these languages.
