Screen Resolutions and Using External Displays

You can use Horizon Client with external displays and you can change screen resolutions.

When you connect a client device to an external display or projector, Horizon Client supports certain maximum display resolutions. You can change the screen resolution that the client device uses to allow scrolling a larger screen resolution.

Enlarging the Screen Resolution for a Remote Desktop

By default, the display resolution is set so that the entire remote desktop fits inside the client device, and the remote desktop icons and task bar icons are a certain size. If you use a larger resolution, the remote desktop still fits inside the client device, but the remote desktop and taskbar icons become smaller.

You can pinch your fingers apart to zoom in and make the remote desktop larger than the device screen. You can then tap and drag to access the edges of the remote desktop.

Changing the Display Resolution Setting

You can use the Resolution setting to set the display resolution to a larger value. If you are using a remote desktop or published application in full-screen mode, tap the Horizon Client Tools radial menu icon, tap the gear icon, tap Display, and tap Resolution. If you are not using full-screen mode, tap Settings in the menu in the upper-right corner of the Horizon Client toolbar. If you are not connected to a remote desktop or published application, tap the Settings (gear) icon in the upper-right corner of the desktop and application selector window.

Using High Quality Mode

You can use the High Quality Mode feature to obtain the best display quality in remote desktops and published applications.

To enable High Quality Mode, before you connect to a server, tap the Settings (gear) icon in the upper-right corner of the Horizon Client window, tap Display, and then tap High Quality Mode. You cannot enable the High Quality Mode setting after you connect to a remote desktop or published application.

The High Quality Mode feature has the following requirements and limitations.

You cannot use the High Quality Mode feature for existing sessions. You must log out and log in to a new session for the feature to take effect.
If the client device has less than an extra-high density (xhdpi) screen, the High Quality Mode setting is not available.
The remote desktop or application must support the High Quality Mode feature.

High Quality Mode is disabled by default.

Using External Displays

You can use the Enable External display setting to configure settings for external displays, such as projectors and attached monitors.

When the Enable External display setting is selected, you can use the following settings.

Presentation mode: When you enable this setting, a keyboard and expanded onscreen touchpad appear on the device when you display a remote desktop on an external display. The expanded touchpad and keyboard appear when you plug the device into the external display. The device detects the maximum resolution provided by the external display.
Multi-Monitor mode: When you enable this setting on an Android device, Horizon Client extends a secondary desktop on an external display. The Unity Touch sidebar is supported only on the client's internal monitor. You cannot change the orientation and full-screen mode. You can interact with remote desktops and published applications on the external display with the onscreen touchpad and full-screen touchpad. You cannot use the physical mouse on the external display.
Keep screen on when external display is connected: This setting keeps the display from turning off after a period of inactivity.
Zoom: Drag this slider to set the resolution for the external display.

If you are connected to a remote desktop or published application, pressing the Back button quits presentation mode or multi-monitor mode and the Enable External display setting is deselected. When the Enable External display setting is deselected, all the external display settings are disabled.

To configure external display settings if you are using a remote desktop or published application in full-screen mode, tap the Horizon Client Tools radial menu icon, tap the gear icon, tap Display, and then tap External Display Options. If you are not using full-screen mode, tap Settings in the menu in the upper-right corner of the Horizon Client toolbar. If you are not connected to a server, tap the Settings (gear) icon in the upper-right corner of the Horizon Client window.

Do not use an external mouse, such as a Bluetooth mouse, when you use the Presentation Mode setting. Instead, use the large onscreen touchpad on the client device.

Using Multi-Monitor Mode on a Chromebook

To enter multi-monitor mode when Horizon Client for Android is installed on a Chromebook, maximize the remote session window. After you maximize a remote desktop window on the Chromebook display, it appears on the external display, or displays, automatically. After you maximize a published application window, you can drag it to an external display. To quit multi-monitor mode, restore the remote session window from the maximized state.

The multi-monitor mode feature has the following requirements and limitations.

Chrome OS M64 or later is required.
Two external displays are supported.
The display topology in the remote session is similar to, but might not be exactly the same as, the display topology that is configured on the Chromebook device.
Unified desktop mode must not be enabled on the Chromebook device.

Changing the Display Zoom Level on a Chromebook Device

When Horizon Client for Android is installed on a Chromebook device and seamless window mode is enabled, you can change the display zoom level for published applications.

To change the display zoom level for published applications, tap the Settings (gear) icon in the upper-right corner of the desktop and application selector window and tap Remote Applications. In the Remote Applications dialog box, you can set the device display zoom level to 100, 110, 125, 150, 175, or 200 percent. You can set the external display zoom level to 100, 150, 200, 250, or 300 percent. The default display zoom level is 100 percent for both the device display and the external display.

This feature has the following requirements and limitations:

Chrome OS M64 or later is required.
You can change the display zoom level for only one external display.
Seamless window mode must be enabled. For more information, see the VMware Horizon Client for Android Installation and Setup Guide document.

You can also enable or disable local storage redirection for published applications from the Remote Applications dialog box. This feature is enabled by default. For more information about this feature, see Share Access to Local Storage with Client Drive Redirection.
