Experience
The Experience tab page allows you to tweak the connection speed to optimize the performance of the connection with the remote server.
In the drop-down list, select your connection speed:
If not sure, select the Detect connection quality automatically option. Please note that if you select this option, all other options, except Enable Compression, will be disabled and will be configured automatically based on the actual connection speed when Parallels Client is connected to Parallels RAS.
If you select a specific speed (e.g. LAN 10 Mbps or higher), select the desired user experience options. If you are connecting to a remote computer on a local network that runs at 100 Mbps or higher, it is usually safe to have all of the experience options turned on. Otherwise, select only the options that you require.
It is also recommended to enable compression to have a more efficient connection by selecting the Enable Compression option.
Enhance windows move/size: Enable this option if you experience graphics artifacts (dark squares) while moving or resizing a remote application window. The issue may manifest itself when an application is hosted on Windows Server 2012 or 2016 and when the Show contents of window while dragging option is enabled.
