Description

Map multiple monitors attached to the Endpoint as a single display to stretch the Application window across all the monitors.


Instructions

To let the session map multiple monitors as a single one, customize "DesiredHPos", "DesiredVPos", "DesiredHRES", "DesiredVRES" settings in the ICA file. Make sure the resolution defined by these settings does not equate to or exceed the actual monitor resolution. We call the Windows API, MonitorFromRect, with the area, and that returns the monitors inside that area. If no monitor is inside the defined area, the API returns a whole single monitor.

For example, if the actual monitors start at (640, 0) with resolution1920*1440, set DesiredHPos to 641, DesiredVPos to 1, DesiredHRES to 1918, DesiredVRES to 1438. Since the defined resolution is less than the actual monitor size, VDA considers the number of monitors as one, even if there are multiple in reality, and the Application window stretches across the monitors as if it were a single monitor.

ICA file settings:
