Configure preference settings - WUYING Terminal - Alibaba Cloud Documentation Center

After you connect to a cloud computer, you can open the assistive ball (DesktopAssistant) on the screen of the cloud computer and configure preference settings based on your business requirements. This topic describes how to configure preference settings for a cloud computer. In this topic, a Windows client of Alibaba Cloud Workspace V6.3.1 is used as an example.

Prerequisites

A cloud desktop is connected.
If you want to enable Media Redirection, your administrator must enable the Media Redirection of Videos by Using VLC feature for the cloud desktop.

Background information

After you open the assistive ball on the screen of the cloud computer, you can configure common features for the cloud computer. On the Preferences > Settings, you can configure the following settings: display resolution, UI scaling, cloud computer dual-displays (only for ASP-based cloud computers), graphic quality, mouse mode, poor network alerting, disconnection notification, and media redirection.

Note

The preference settings on a cloud computer vary based on the type and version of the Alibaba Cloud Workspace client that you use to connect to the cloud computer. The preference settings that are displayed on the cloud computer that you use shall prevail.

Configure display preferences

Open the assistive ball on the screen of the cloud computer and choose Settings > Preferences > Display. On the Display tab, you can configure the following parameters: Display Resolution, UI Scaling, Media Redirection, and Cloud Computer Dual Displays. The following table describes the parameters.

Parameter	Description
Display Resolution	The screen resolution of the cloud computer. The supported resolutions vary based on the client type. The actual resolutions that are provided shall prevail. Note To configure the display resolution of the cloud computer, open the assistive ball, choose Settings > Preferences > Display, and then specify a value for the Display Resolution parameter based on your business requirements. The display resolution of a cloud computer that is connected from a Windows or macOS client of Alibaba Cloud Workspace can automatically adapt to the resolution of the on-premises computer. A non-GPU-accelerated image supports the highest resolution of 1920 × 1080. A GPU-accelerated image supports the highest resolution of 4K. If you require a high resolution, such as 4K, we recommend that you purchase a GPU-accelerated image. Make sure that the on-premises device that carries the WUYING client also supports the resolution. You cannot switch between non-GPU-accelerated images and GPU-accelerated images.
UI Scaling	If the applications or text on the cloud computer are blurred or appear tiny due to a resolution discrepancy, configure the UI Scaling parameter based on your business requirements to enlarge the UI. This setting is related to the window size of the cloud computer. A larger monitor provides a larger window, which in turn provides more options to adjust the UI.
Media Redirection	If you want to pre-install a VideoLAN Client (VLC) video player on the cloud computer and use the player to play lossless and HD videos, we recommend that you enable the media redirection feature.
Cloud Computer Dual Displays	If an extended monitor is connected to the on-premises device, you can use the dual-display feature by setting the Cloud Computer Dual Displays parameter to Yes. When the cloud computer enters the full-screen mode, the dual-screen mode of the cloud computer complies with the multiple-display settings of the on-premises device. This setting takes effect only for the cloud computer on which the operation is performed. If you modify the setting, you must exit and re-enter the full-screen mode for the modification to take effect. For information about specific operations, see the "Dual-screen mode" section of the Use the full-screen and dual-screen modes topic.

Configure graphic quality preferences

Open the assistive ball on the screen of the cloud computer and choose Settings > Preferences > Graphic. On the Graphic tab, specify a value for the Highest Graphic Quality parameter based on your business requirements, or select between Best Quality and Best Performance.

Parameter	Description
Custom	After you select Custom on the Graphic tab, you can configure the Maximum Frame Rate and Highest Graphic Quality parameters based on your business requirements. Maximum Frame Rate: specifies the number of frames that are continuously displayed on the monitor per second. A larger number of frames indicates smoother graphic performance. Unit: FPS. Valid values: 10 to 60. Highest Graphic Quality: The graphic quality of the cloud computer varies based on the graphic quality features that are enabled by your administrator. If the current graphic quality feature that is in effect cannot meet your business requirement, contact your administrator to enable more graphic quality features. Valid values: Low, Medium, High, and Lossless. Note A higher frame rate indicates better graphic quality but higher requirements on the on-premises device and network. The real-time frame rate and graphic quality are dynamically adjusted based on the on-premises device and network.
Best Quality	If you select Best Quality, the cloud computer can support up to 30 FPS and provides high graphic quality. You cannot change the maximum FPS or graphic quality.
Best Performance	If you select Best Performance, the cloud computer can support up to 60 FPS and provides medium graphic quality. You cannot change the maximum FPS or graphic quality.

Configure control preferences

Open the assistive ball on the screen of the cloud computer and choose Settings > Preferences > Control. On the Control tab, you can configure the keyboard shortcut handling and mouse mode. The following table describes the parameters.

Parameter	Description
Keyboard Shortcut Handling	If you select the check box and your cloud computer is not in the full-screen mode, the system of the cloud computer intercepts keyboard shortcuts after you click anywhere in the desktop window. If you clear the check box, the system of the cloud computer does not intercept keyboard shortcuts even if you click anywhere in the cloud computer window.
Mouse Mode	The default value of this parameter is Absolute Mouse. If your pointer erratically moves when you play games or use 3D software on the cloud computer, you can set this parameter to Relative Mouse for a normal mouse movement. Note You can set this parameter to Absolute Mouse or Relative Mouse only for cloud computers that are connected from a Windows client of Alibaba Cloud Workspace V5.0.0 or later.

Configure DesktopAssistant preferences

Open the assistive ball on the screen of the cloud computer and choose Settings > Preferences > DesktopAssistant. On the DesktopAssistant tab, you can configure whether to receive notifications upon poor network connection and cloud computer disconnection. The following table describes the parameters.

Parameter	Description
Poor Network Connection Alert	Specifies whether to report alerts upon poor network connection. If you set this parameter to Enable, the system reports an alert when it detects a weak network connection.
Disconnection Confirmation	Specifies whether to show a pop-up for disconnection confirmation when you disconnect from the cloud computer. If you set this parameter to Enable, a pop-up window asking for your confirmation appears when you disconnect from the cloud computer.
