Key Features

VMware Horizon Client for Chrome makes it easy to access your remote desktops and published applications from your Chromebook with the best possible user experience on the Local Area Network (LAN) or across a Wide Area Network (WAN).

  • Work the way you want to - Use your Chromebook to work on your remote desktops and published applications from any location. Support for the VMware Blast display protocol from VMware means your remote desktop or published application is fast and responsive, regardless of where you are.
  • Simple connectivity - Horizon Client for Chrome is tightly integrated with VMware Horizon for simple setup and connectivity. Open Chrome, enter a server URL, and log in to see a list of available remote desktops and published applications.
  • Secure from any location - At your desk or away from the office, your data is always secure. Enhanced certificate checking is performed on the client. Horizon Client for Chrome also supports optional RADIUS and RSA SecurID authentication.

What's New in This Release

Horizon Client for Chrome 2111 includes the following new features.

  • Media Optimization for Microsoft Teams
    This release adds support for the Media Optimization for Microsoft Teams feature, which redirects Teams audio calls, video calls, and viewing desktop shares to the client machine for processing. See Configure Media Optimization for Microsoft Teams in Horizon Client for Chrome.
  • Geolocation Redirection
    You can enable geolocation redirection to use the location service of the local device in remote desktops or published applications. See Share Location Information.
  • Windows System Tray Redirection
    The Windows System Tray was not available. This feature adds a bar to simulate the behavior of Windows System Tray.
  • Enhanced File Association Feature
    You can associate Chrome Native Client apps with file types. See Set File Association.
  • DPI Synchronization Feature
    This feature provides you with the ability to synchronize the DPI in live sessions to optimize viewing based on the monitor. See Using DPI Synchronization.
  • Ability to Modify the Behavior of the Backspace Key
    You can activate the setting, Enable Alt-Backspace, to change the behavior of the Backspace key. The Backspace key deletes text to the left of the cursor. When this setting is enabled, the Alt+Backspace key combination deletes text to the right of the cursor.

Before You Begin

  • Horizon Client for Chrome requires Chrome OS 75 or later.
  • Horizon Client for Chrome is supported with the latest maintenance release of Horizon 7 version 7.5 and later releases.
  • Install and upgrade Horizon Client for Chrome just as you do any other Chrome app. You can get the latest version of the app from the Chrome Web Store.
  • For system requirements and installation instructions, see the VMware Horizon Client for Chrome Installation and Setup Guide document.

Known Issues

  • If you enter an incorrect PIN during smart card authentication, Charismathics does not present any direct feedback in the dialog box.

    Workaround: This problem is a third-party issue. For more information, go to https://support.google.com/chrome/a/answer/7014689.

  • You might encounter the following problems after authenticating with a smart card:

    • If you enter an incorrect PIN, log off from the server, and then immediately log in to the server again, you are prompted for Active Directory authentication.
    • If you log off from a session and then log in to the server again, the server fails to authenticate with smart card authentication.
    • If your published application session is idle and times out, and you unplug and and then reinsert your smart card reader, you are not prompted for your PIN when you try to connect to a published application.

    Workaround: Log off or restart the Chromebook and log in with the smart card again.

  • H.264 decoding does not work in this release. The setting to enable H.264 decoding has been removed from the Horizon Client user interface.

    Workaround: None.

  • After dragging certain apps to a small monitor, the app might have a strange boundary on Horizon Client for Chrome.

    This issue only appears when Chromebook has a very high DPI or an extended monitor has a small resolution.
    An example condition would be Chromebook with 4K(3840) screen in 213% DPI scale + small extended monitor(1920) in 100%. An example app could be a calculator that is not resizable.

    You can make the following changes:
    1. Enable High Resolution.
    2. Change to a larger extended monitor. A 2560 screen will resolve the issue in most of cases.
    3. For Chromebook, set the display scale to lower DPI (smaller font and icon) .

  • The Media Optimization for Microsoft Teams feature becomes unavailable after a network interruption occurs on the Horizon Client session. For details, see VMware Knowledge Base (KB) article 85761.

  • During a Teams audio call with the Media Optimization for Microsoft Teams feature enabled, no alert message appears when the user speaks with the microphone muted.

    Workaround: None

  • When sharing the screen during a Teams video call with the Media Optimization for Microsoft Teams feature enabled, if the client user locks and then unlocks the Chrome OS, the screen share and outgoing video stop working.

    Workaround: None

  • When the client user minimizes the remote desktop window during a Teams screen-sharing session with the Media Optimization for Microsoft Teams feature enabled, the screen-share contents turn black.

    Workaround: None
