Menu path: Setup > Sessions > Citrix XenDesktop / XenApp > HDX / ICA Global > Window
The following settings are configured under Window:
For Legacy ICA Sessions Only:
Default number of colors: Specifies the standard color depth - the default setting is a color depth of 256 colors.
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. If Approximate Colors is enabled, flashing when switching between windows is avoided.
Default Horizontal Resolution: Horizontal resolution in pixels
Default Vertical Resoultion: Vertical resolution in pixels
Font smoothing: Enables font smoothing - in the event of performance problems, font smoothing should be switched off as it requires additional computing power.
For All Citrix Sessions:
Multi Monitor: Configure whether the full-screen mode is to be extended across all monitors.
XenApp/StoreFront Start Monitor: Start session window on the selected monitor.
Embed Systray Icons into Window Manager taskbar: Inserts an application icon into the local taskbar
Control Bar for Citrix Sessions: Enable a control bar for minimizing or quitting a full screen session.
