Menu path: Setup > Sessions > Citrix XenDesktop/XenApp > HDX/ICA Global > Window
Under Window, you can configure the following settings:
Only for Legacy ICA sessions
Default Number of Colors: Specifies the default color depth.
Approximate Colors:Given the differences between the color palettes used by the ICA client and the thin client desktop, the screen may flash annoyingly if you switch between windows on a pseudo-color screen. The ICA client's color adaptation scheme prevents this flashing as it uses the colors from the local desktop palette in order to display the ICA window session.
Flashing when switching between windows is avoided.
Default window width: Specifies the window width in pixels (default: 640).
Default window height: Specifies the window height in pixels (default: 480)
Font smoothing: Enables font smoothing - in the event of performance problems, font smoothing should be switched off as it requires additional computing power.

Restrict full-screen session to one monitor
Extend full-screen session to all monitors
XenApp/StoreFront start monitor: Select the monitor on which the session is to start.
Embed systray icons in taskbar: Inserts an application icon into the local taskbar.
