Changing the Display Resolution Setting
You can use the Resolution setting in the Settings dialog box to set the display resolution to a larger value. If
you are not using full screen mode, use the Horizon Client toolbar to display the Settings dialog box. If you
are using full screen mode, tap the Horizon Client Tools icon and tap the settings icon. Drag the slider in the
Touchpad Sensitivity option. For a picture of the settings icon in the Horizon Client Tools radial menu, see
“Horizon Client Tools,” on page 38.
Screen Resolutions for Using Projectors
You can use the Resolution setting to set a larger resolution for projectors.
You can use the Presentation mode setting in the General settings list to display the keyboard and an
expanded onscreen touchpad on the device while displaying the remote desktop on the projector or
attached monitor. The expanded touchpad and keyboard appear when you plug the device into the external
monitor. The device detects the maximum resolution provided by the external display. Currently, the
presentation mode feature is supported only if you have Android 4.2 on the following devices: Google
Nexus 4, Google Nexus 10, and Samsung Galaxy S 4.
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 Stay awake setting to keep the display from turning off after a period of inactivity while in
presentation mode.
Do not use an external mouse, such as a Bluetooth mouse, when using the Presentation mode setting.
Instead, use the large onscreen touchpad on the Android device. If you attempt to use a mouse, the mouse
pointer might not be able to move to the bottom or right side of the screen, and when moved to the top of
the screen, might conflict with some of the function keys shown on the large onscreen touchpad, rather than
the top of the remote desktop.
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 250MB.
