I have a HP laptop (Windows 11) with two external monitors connected via DELL 6000 dock. Both monitors were working fine in extend mode. This morning, both stopped working. However when I opened a power point presentation and started slide show, they started working. I turned off the slide show and they stopped working again. I have tried following with no luck so far.
- Restarted both computer and dock
- Plugged / unplugged USB-C cable.
- Attached dock to my other laptop to see if there is a hardware or cable issue with the dock. It works find on the other computer suggests no issues with the dock or the cable.
- Restarted computer while slide show was still on (solution suggested in the following thread. external displays receive input signals ONLY when I open a Powerpoint file and use slide show mode?)
So far, nothing has worked. Monitors only work when slide show is on. As soon as I turn off the slide show. Monitors go blank and shows there is no signal.
