    Elastic Desktop Service:User experience policies

    Last Updated:Mar 27, 2026

    In Elastic Desktop Service (EDS), policies manage settings for user experience, security, auditing, peripherals, collaboration, and AI. This topic describes the policy settings related to user experience.

    Display

    Display settings determine the visual quality of a cloud computer.

    Configuration

    Parameter

    Description

    Display mode

    Controls the cloud computer's display mode. The following options are available:

    • User-defined

      If you select this option, you also need to set Image Quality. End users can switch the display mode on their terminals. For more information, see Set Keyboard Response Mode and Mouse Mode.

    • Daily Office

      Ideal for common office tasks like document editing and video viewing. This option locks the display mode to Intelligent Mode.

    • Design and 3D applications

      Ideal for graphically intensive tasks like design and 3D applications. This option locks the display mode to Smoothness First.

    • Custom

      Allows you to configure specific parameters that affect the visual quality of the cloud computer, such as adaptive scenarios, color enhancement, and smoothness enhancement.

    Image quality policy

    Enable this setting to improve the visual quality of the cloud computer. For graphics cloud computers, especially those used for design workloads, we recommend enabling this setting to enhance performance and user experience.

    Note

    This setting applies only to graphics cloud computers that use the HDX protocol.

    Resolution setting

    Controls the cloud computer's screen resolution. The following options are available:

    • Adaptive

      The cloud computer resolution automatically adjusts to match the display area of the client.

    • Fixed

      The resolution does not change with the client's display area. The resolution remains fixed at the value you enter. Some applications may cause the resolution to change. The DPI is fixed at 100.

      Note

      The default fixed resolution is 1920×1080px. The minimum value is 640×480px, and the maximum value is 4096×2160px. The pixel values must be even numbers.

    Connection

    Connection settings control the cloud computer's connection behavior and performance.

    Applicability

    Parameter

    Protocol type

    Minimum image version

    Client and minimum version

    Network transmission (UDP and TCP modes)

    Adaptive Streaming Protocol (ASP)

    V1.0.0

    Any client type, V5.2.0 or later

    Network transmission (AUTO and AST modes)

    ASP

    V1.5.0

    Any client type, V6.5.0 or later

    Configuration

    Parameter

    Description

    Network transmission

    Supported network transmission modes include:

    • AUTO mode: Automatically switches between AST mode and UDP mode based on the visual content of the cloud computer.

    • UDP mode: Delivers higher definition and is suitable for office and high-definition graphics design scenarios.

    • AST mode: Delivers higher smoothness and is suitable for scenarios with frequent audio and video usage.

    • TCP mode: Provides a higher connection success rate and is suitable for environments where UDP or AST mode is restricted.

    Note

    • By default, network transmission uses UDP mode. If the network for the cloud computer has UDP port restrictions, such as from anti-attack policies or rate limiting, select TCP mode.

    • If an administrator selects AUTO or AST mode but the user's cloud computer does not meet the requirements, the client automatically falls back to TCP mode.

    Maximum auto-reconnect retry duration

    Specifies the maximum time, in seconds, for automatic reconnection attempts after a connection failure. Valid values: 30 to 7200.

    Media redirection

    Media redirection offloads media processing to the end user's device. This enables local playback of audio and video, providing a smoother media experience.

    Use cases

    Audio and video processing are compute-intensive operations that require significant system performance. Enabling media redirection provides the following benefits:

    • Reduces resource consumption on the cloud computer by offloading multimedia processing to the end user's device, which can decrease compute power usage by up to 80%.

    • Supports a wide range of media formats, making it suitable for various use cases.

    • Enables lossless playback of high-definition (HD) audio and video files (2K or higher) on low-specification cloud computers by using the pre-installed VLC media player.

    • Reduces latency during audio and video playback on the cloud computer, providing a smoother media experience for end users.

    Limitations

    Item

    Description

    Client type

    This is supported only for the Windows client and the macOS client of version V6.1.0 or later.

    Cloud computer OS image

    Supported only on Windows images that use the ASP protocol. Linux images are not supported.

    Video resolution

    • TCP protocol: Supports mainstream audio and video media with a resolution of 4K or lower.

    • UDP protocol: Supports mainstream audio and video media with a resolution of 2K or lower.

    Player

    Supported only on the VLC media player.

    Note

    The VLC media player on the cloud computer does not support audio or video effects.

    Audio and video file formats

    Supported audio and video formats for the VLC media player include MP4, AVI, AAC, OPUS, and MP3.

    Full-screen or multi-monitor

    • Full-screen mode is not supported. You can only zoom, stretch, or drag the video window.

    • Only single-monitor setups are supported. If you use a dual-monitor setup, you cannot play video files with media redirection on the extended display.

    End user scenario

    If an end user shares their screen from a cloud computer during a remote assistance session, other participants cannot view content played via media redirection.

    Configuration

    Parameter

    Description

    Media redirection

    Enables media redirection.
