Hi,
We've been experiencing lots of issues in the school with the majority of our Clevertouch Plus 65" models and the PCs they are connected to via HDMI.
Teachers are regularly complaining of the Clevertouch screens not mirroring the displays and being either blank or saying "NO SIGNAL".
All PCs are the same model, Lenovo M800Z All-In-One, fully updated.
The PCs are configured with power settings as follows:
Turn off Hard Disk: Never
Sleep: After 60 minutes
[TABLE=class: subtable3]
[TR]
[TD]Turn off display after: After 30 minutes[/TD]
[TD][/TD]
[/TR]
[/TABLE]
Allow hybrid sleep: On
Hibernate after: Never
I'm starting to pull my hair out over this! Occasionally, I can get the picture back by switching the cable on the Clevertouch from HDMI1 to HDMI2. Returning it to HDMI1 fails to bring the picture back.
Surely the Turn the Display off option can't be causing this?
Any help much appreciated.
Paul
