You can use Horizon Client with external displays and you can change screen resolutions.
When you connect your device to an external display or projector, Horizon Client supports certain maximum display resolutions. You can change the screen resolution used on your device 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 Windows desktop fits inside your device, and the desktop icons and task bar icons are a certain size. If you change the default to a higher resolution, the desktop still fits inside the device, but the desktop and taskbar icons become smaller.
You can pinch your fingers apart to zoom in and make the desktop larger than the device screen. You can then tap and drag to access the edges of the desktop.
Changing the Display Resolution Setting
To change the resolution from a remote desktop or application, tap to expand the Horizon Client Tools radial menu icon, tap the Settings (gear) icon, and tap Resolution. You can also change the resolution from the Horizon Client Settings window. Tap Settings at the bottom of the Horizon Client window and tap Resolution.
Using High Resolution Mode
You can use the High Resolution Mode feature to obtain the best display quality in remote desktops and applications.
You can enable High Resolution Mode from the Horizon Client Settings window. Tap Settings at the bottom of the Horizon Client window, tap Resolution, and tap to toggle the High Resolution Mode setting to on. To enable High Resolution Mode if you are using a remote desktop or application, tap to expand the Horizon Client Tools radial menu icon, tap the Settings (gear) icon, tap Resolution, and tap to toggle the High Resolution Mode setting to on.
The High Resolution Mode feature has the following requirements and limitations:
- You cannot use the High Resolution Mode feature for existing sessions. You must log out and log in to a new session for the feature to take effect.
- You must have an iPad Pro, or an iPad or iPad mini with Retina display, to use the High Resolution Mode feature.
- The High Resolution Mode feature requires Horizon Agent 7.0.3 or later.
High Resolution Mode is disabled by default.
Using External Monitors and Projectors
You can use the Resolution setting to set a larger resolution for external monitors and projectors.
To display the keyboard and an expanded onscreen touchpad on the device while displaying the remote desktop on the projector or attached monitor, enable the Presentation Mode setting. 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.
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 enabled, you can click Done to switch to mirror mode.
You can 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.
You can configure these setting from a remote desktop or application by tapping to expand the Horizon Client Tools radial menu icon and tapping the Settings (gear) icon. You can also configure these setting by tapping the Settings (gear) icon at the bottom of the Horizon Client window.
Hiding Sensitive Information on External Displays
When you use Horizon Client with an external monitor or projector, sensitive information, such as passwords and passcodes, is automatically hidden to protect user data security.
