Issue With Dual Monitors On Laptop

So, this is the setup:
Laptop - HP ProBook 465 G11 Notebook PC
OS - Windows 11 Pro (up-to-date)
Hub - HP USB-C Dock G5
Monitors - (2) 27in Asus
Monitors, Audio, Network all run through the Hub. Laptop connects to the Hub.

Up until a month or so ago, this setup was working as it should... sit down, connect laptop to the Hub and all (3) monitors worked and flowed well. Then something happened... the second external monitor stopped working. Tried various things, different cords, different Hub - nothing is working.
I thought maybe a power setting needs to be changed but now I am wondering if there was a Windows update that is causing a problem.

Here is the added bonus, have a another laptop with dual monitors same setup - it, too, has run into similar issue with external monitors not firing up properly like they did initially.

Anyone else run into this sort of problem? Anyone have a thought?
Thanks in advance....

Did you try switching/swapping the monitors between ports to make sure the/a monitor isn't the problem?

When you tried different hubs, did you boot the computer WITHOUT the hub(s) connected & then plug in the hub and then plug in each additional device one at a time making sure each is recognized before plugging in the next device? (even going so far as to changing the order each device is connected)?

Can and/or is there a way you can check to see IF your Win 11 recently updated?

Have you tried to restore Win 11 back to a restore point that is PRIOR to your one monitor being out to see IF that MIGHT correct the problem?

Outside of Win 11 has ANY installed software/apps, Drivers been recently updated?

Have you installed any software/apps recently or even just before the problem showed up?

I don't know Win 11 to know IF these settings options are the same or similar to Win 7 or not, but have you checked the monitor settings in Win 11 to make sure ALL 3 monitors are "On"/selected to be active? How do you have the monitors set to function in relation to the Main Desktop? Is each monitor displaying different things/desktops?

Do you know IF there is any Monitor(s) settings in BIOS on the laptops? Is it possible the BIOS could have updated and/or settings changed without you knowing? Maybe the BIOS Backup batteries died on both causing loss of settings (I know this is a very remote possibility happining to 2 computers at the same time but still possible).

 

D.H.:

Did you try switching/swapping the monitors between ports to make sure the/a monitor isn't the problem?
>>> Yes. Switched monitors. Cables.

Can and/or is there a way you can check to see IF your Win 11 recently updated?
>>> Yes. Everything is up-to-date. I even gave thought to it being an update that threw it into it's current state.

Have you tried to restore Win 11 back to a restore point that is PRIOR to your one monitor being out to see IF that MIGHT correct the problem?
>>> No. Did not think of that but at this point it might be too far back to try this one.

Outside of Win 11 has ANY installed software/apps, Drivers been recently updated?
>>> No. Not that I know of.

Have you installed any software/apps recently or even just before the problem showed up?
>>> No. Again, if anything installed or updated, it was Windows.

When you tried different hubs, did you boot the computer WITHOUT the hub(s) connected & then plug in the hub and then plug in each additional device one at a time making sure each is recognized before plugging in the next device? (even going so far as to changing the order each device is connected)?
>>> In a way, I have tried this but might circle back and try how you phrased to see if that has some merit.

I don't know Win 11 to know IF these settings options are the same or similar to Win 7 or not, but have you checked the monitor settings in Win 11 to make sure ALL 3 monitors are "On"/selected to be active?
>>> Yes. Have checked and re-checked. Sometimes the "third" monitor is showing but showing as Inactive or not showing at all.

How do you have the monitors set to function in relation to the Main Desktop?
>>> To extend the main screen.

Is each monitor displaying different things/desktops?
>>> No.

Do you know IF there is any Monitor(s) settings in BIOS on the laptops? Is it possible the BIOS could have updated and/or settings changed without you knowing? Maybe the BIOS Backup batteries died on both causing loss of settings (I know this is a very remote possibility happining to 2 computers at the same time but still possible).
>>> Good thought but no. I am fairly certain there is no monitor settings in the BIOS other than the ordinary setting(s).

Thanks for you rather in depth Q&A on the matter. You did give me an idea or two to try.
