You can extend a remote desktop to multiple monitors. If you have a high-resolution monitor, you can see the remote desktop or application in full resolution.
The All Monitors display mode displays a remote desktop window on multiple monitors. The remote desktop window appears on all monitors by default. You can use the selective multiple-monitor feature to display a remote desktop window on a subset of your monitors.
If you are using All Monitors mode and click the Minimize button, if you then maximize the window, the window goes back to All Monitors mode. Similarly, if you are using Fullscreen mode and minimize the window, when you maximize the window, the window goes back to Fullscreen mode on one monitor.
If you have Horizon Client use all monitors, if you maximize an application window, the window expands to the full screen of only the monitor that contains it.
