I tried various different fixes, firmware, drivers etc, now working fine but only after I swapped the PC for one with an HDMI port which eliminated the need for the DisplayPort/HDMI Converter

I ended up having to find a PC with HDMI output, it is now working, no Display port/HDMI converter installed now.

As a crude fix I've realised that I can run a 3.5mm jack - 3.5mm jack cable from the PC into the Mic socket on the ActivPanel which should get it working. It's not the fix I want though!

The thing is that I've tried this on two separate models of HP Mini PCs, with different chipsets and driver types, and upgraded the drivers on both machines, and it happened on both..

I'm having the exact same issue, has anyone else experienced this or have a fix for it, I'm using an HP Elitedesk Mini with HP DisplayPort adapter and have tried a G1 and G3 model, I have also tried the following: Tried 2 different chipset model desktops (HP Elitedesk G1 and G3) 2 different DisplayPort adapters - generic + genuine HP 2 different HDMI cables Firmware upgrade on the Activpanel Promethean driver upgrade Intel Graphics driver upgrade Desktop PC BIOS upgrade Promethean Support call - the only suggestion they had was to try it on a computer with an HDMI port, due to the location of the computer this will be very difficult, a standard sized desktop won't fit. As Jon said above, physically switching the DisplayPort cables (Activpanel and monitor) kicks it back to life but it is very annoying for the teacher. Any suggestions would be gratefully received
