Deploy Citrix Workspace app / Receivers. On the left, click the Stores node. In the middle, right-click your store, and click Manage Receiver for Web Sites. Click Configure. On the Deploy Citrix Receiver/ Workspace app page, check the box next to Allow users to download HDX engine (plug in). Having the same issue connecting Workspace app on macOS Catalina. 'Citrix Workspace cannot connect to the server. Check your network connection.' MacOS Catalina 10.15.4 and Workspace App 20.02.0.5. And other Mac with Workspace app 19.12.0.23 It has to be an issue with the latest Catalina updates.
Note: While there are no controls in place to limit resolutions above 4K in Windows 10 VDAs, Citrix development testing is limited to 4K monitors currently.
High-DPI (dots per inch)
Current support for High DPI endpoints is based entirely on the Citrix Receiver or Workspace App capabilities for a given platform. Citrix Receiver for Windows 4.10 (or greater) and Citrix Workspace App for Windows are the only DPI aware clients available currently. These clients can be configured to either scale the session, ignore DPI settings and set the full native resolution, or match ( with VDA versions 1811 or newer) client resolution and DPI settings on the VDA. Refer to CTX230017 - Display DPI scaling configuration with Receiver for Windows for additional information. Clients that are not DPI aware rely entirely on the OS to scale the application as appropriate to the endpoint DPI settings. This means that the Receiver or Workspace App can behave differently depending on the OS. Multi-monitors with different DPI scales are not supported with clients that are not DPI aware.
Performance and scalability considerations
In the context of display remoting the size of a user session can vary significantly based on display resolution and the number of monitors alone. As the session grows in size more server and client resources are required, for rendering and encoding/decoding of the graphics, and more data needs to be sent from the server to the client via the network. This has a direct impact to session performance and server scalability. Citrix highly recommends taking user requirements with respect to display configuration into account as it relates to server hardware, network links, and endpoint devices. Some deployment considerations are listed below:
- Both display resolution and the number of monitors increase the session size. A user connecting from and endpoint with a single 4K monitor would result in the same session size as a user connecting with four 1080p monitors. Single server scalability can be reduced significantly by simply upgrading user endpoints with 4K monitors. If 4K monitor support is required additional server resources should be allocated accordingly to maintain desired user density levels.
- Bandwidth requirements will also increase with higher resolutions and the number of monitors in use. Bandwidth constraints could limit frame rates and reduce image quality affecting session interactivity and user experience as a result.
- The endpoint device must have adequate hardware resources available to support the desired display configuration. This could mean having enough CPU resources and in some cases a GPU that can handle the graphics workload. Performance limitations of Thin Clients may become apparent at high resolutions such as 4K, for example.
