This article applies to the following ScreenBeam products:

ScreenBeam can support wireless touch and pen writing for the Windows 10 Miracast connected device.  This means the presenters and their Windows device are not required to be tethered to the interactive touchscreen display.   Presenter could wirelessly project from anywhere within the room and utilize the touchscreen to control contents residing on the device. 

Some benefits of having wireless display with touch including:

• Users can bring their own apps for team collaboration
• Notes can be stored directly on the meeting host device
• Quicker setup thus reduces the time/cost of running long cables. 

This article provides instructions on how to setup ScreenBeam with a touchscreen display.

Touchscreen wired setup

The traditional touchscreen setup requires the PC to be connected to the display using a video cable (i.e. HDMI) and a USB cable.  

Touchscreen wireless setup with ScreenBeam

ScreenBeam acts as a wireless bridge between the PC and the touchscreen display.   

Dell touchscreen display with Optiplex miniPC and ScreenBeam setup 

In some circumstances, the touchscreen display might be connected to an in-room PC for other purposes and may conflict with ScreenBeam.   For the Dell touchscreen display with an Optiplex miniPC and ScreenBeam setup, the wireless touch feature is limited as the touch input is occupied by the Optiplex miniPC. 

In this setup, ScreenBeam AV output is typically routed through an HDMI-to-USB capture device and in to the in-room PC.  The main reason for this setup is to capture the in-room presentation and loop it through a selected (UC) Unified Communication application to distribute to the remote participants. 

The setup needs to be rearranged to support Miracast wireless touch along with wireless display.

Touchscreen display with UC System and ScreenBeam setup 

In setups where the touchscreen display is connected to a UC System (i.e. Zoom Rooms or Teams Rooms),  ScreenBeam AV output is typically routed through the UC System HDMI Input port.  The main reason for this setup is also to capture the in-room presentation and distribute to the remote participants.  

The wireless display touch function can be supported as long as the USB touch input is connected to ScreenBeam.
