"True Multiple Monitor" is supported by Thinstuff XP/VS Server, which means that remote-desktop-sessions can be distributed across mulitple monitors with high-resolution displays.
Span-Mode is known since Windows Vista, the remote-desktop-session can be display across mulitple monitor. This mode is also called "stretched" mode, because all monitors are
connected together to a single, large monitor. There are a few disadvantages:
* Each monitor needs the same resolution and colour depth setting
* Task-bar will cover both monitors
* Popup dialogues will appear half on one, half on the other monitor
Since Windows 7 / 2008 R2 Multiple Monitors is supported. The client’s monitors can be arranged in any order with different resolutions.
Requirements Client-Side for Multiple Monitors
- RDP-Client 7.0 or higher
- Resolution: provided that the total resolution per monitor must be under 4096 x 2048 pixels. The resolution of displayed RDP-session can be configured in the Group Policy Editor (Computer Configuration/ Administrative Templates/ Windows Components/ Remote Desktop Services/ Remote Desktop Session Host/ Remote Session environment -> on the right pane select “Limit maximum display resolution”)
Requirements Server-Side for Multiple Monitors
- “multiple monitor via RDP” till Windows 7 / 2008 (R2) as well as Windows 10 / 2012 (R2)
