HDMI™ Input Connection Issues on Logitech Tap Touch Controllers with ClickShare Devices

Issue

• Some Logitech Tap touch controllers fail to recognize the HDMI™ connection from ClickShare devices after toggling the HDMI™ output. This issue occurs when the ClickShare device wakes up from standby or activates screen output during content sharing.
• Analysis has shown that this might be related to the ‘hotplug’ detection behaviour in certain Logitech TAP hardware revisions.
• Rooms where the HDMI™ connection between ClickShare and Logitech Tap is routed through a switcher are usually not affected. 

Verification

Steps to verify your problem is related to this compatibility issue using a standard Laptop (without a ClickShare device in the loop)

1. Connect a standard laptop or PC HDMI™ output to the Logitech Tap HDMI™ input.
2. Verify that the display is showing on the MTR/ZR screen.
3. Go to Settings -> Displays.
4. Select the display showing on the Logitech Tap.
5. Switch off the display by selecting “Show only on 1” in the lower left corner of the layout.
6. Wait until the MTR/ZR disables the screenshare.
7. Switch the display back on.
8. Press the content share button on the MTR/ZR Controller.

If the Logitech Tap does not recognize the HDMI™ signal and the MTR displays “Please connect HDMI™ cable” after the screenshare is activated, your Logitech Tap might be affected. 

Solution
