They initially advised me to update the firmware from version 1.2.16.0, which the device was using when it was delivered in Jan 2024, to the latest version 1.2.17.0. This did not resolve the issue, so I am waiting for hear back from HP Support for further instructions.

Here are the workarounds I found so far. This is about using the HP Z34c G3 monitor in a dual computer configuration where a desktop is permanently connected via USB-A. A laptop is normally used connected via USB-C and the laptop is currently not connected. Windows 11 power saving has put the desktop screen to sleep, the monitor has gone to sleep and can't be woken up by simply moving the mouse.
Workarounds:
1. Press and quickly release the power button on the desktop attached via USB-A to wake up the desktop.
2. Attach a second mouse directly to the desktop attached via USB-A and move the mouse to wake up the desktop.
3. Plug the USB-C cable back into the laptop that was previously using this connection. Power on the laptop (USB-C computer). Use the KVM function to toggle the monitor to the desktop connected via USB-A by pressing the left Ctrl key on the keyboard connected to the monitor twice (repeat if necessary) and move the mouse to wake up the desktop connected via USB-A.
What else I tried that didn't work:
- Turning the monitor off and back on again, then moving the mouse.

I recently got a new desktop (bigger, faster, etc.) and so I've hooked this up via HDMI in addition to the original desktop on DisplayPort. Now even if the new desktop isn't powered up, I now have no problem to wake up the original desktop by moving the mouse and pressing a keyboard key. That seems very strange, but it is a welcome relief.
It doesn't seem like anybody else has the same problem, as there have been no replies here. In the meantime HP Support has proposed to exchange the monitor hardware under warranty, so we'll see if that solves my issue or not.

I don't know if this is in the same area. Lacking the skill is a bleep but age does things! I have a desk top and an All-in-One tied together via HDMI. One difference, I was running a diferent - OLD - desktop. There was a time, years ago?, when I could boot either computer on its own now the All-in-One tells me there is no HDMI cord and the monitor is turned off (these messages are given to me on the "turned on" monitor/Al-in-One.
Machines HP Pavilion Gaming Desktop TG01-2260xt and HP Pavilion All-in-One - 27-r015z. The All-in-One is ageing but the desk top is strong enough and new enough to be ok,
