every morning.
Samsung Notebook 3 PRo 360. Connected to a docking station and then a 48" Samsung Curved display. and every single freaking time.
I have tried other docking stations. I have tried many things.
Only thing that works is boot. Unplug and replug in HDMI cable. once for connection and then sometimes again to get the Display settings correct.
Once it is working it is great.

Just curious...
Did you try turning them all off (actually off) and then try turning them on in different order?

I have a different setup which uses multiple USB-to-DVI adapters to drive several displays from my laptop via a dock and a KVM switch.
Due the the chains of USB hubs (some internal to the laptop) it's often the case that one or more displays don't come up, either on power on or when I do a keyboard/display/mouse switch.
I found a Windows-provided utility PNPUTIL which will list PNP devices which have problems so I parse the output to issue disable and enable commands for each one. This resets them and they come online so I don't have to go round unplugging and plugging in devices!
pnputil /enum-devices /problem|select-string "Instance ID"|Foreach-object {$_ -match "Instance ID:\s+(?<root>.*)";$x = $matches['root'];Invoke-Expression -Command "pnputil /disable-device ""$x""";Invoke-Expression -Command "pnputil /enable-device ""$x"""}
Since HDMI connections must be Plug-N-Play in a similar way this might work for them too. I don't have an HDMI connected monitor to test.

I'll lose a monitor if the cat jiggles the HDMI cables. Then it's not straight forward getting it back. I think multi-monitor support in general is "weak" (like setting focus to a monitor that isn't even on).

I have had this issue in Linux, but it's usually a driver issue and/or KDE not playing to friendly with external monitors on laptops.
Back in Win10, I always had problems with external monitors on a laptop with coming back from sleep mode and having all of my windows moved around because it went through several cycles of resetting the resolution every time. Less of an issue in Win11 though, so we may have to sell our soul but at least our windows stay put.

I had that problem with my Thinkpad. I now have an HP, and I have 3 external monitors connected and have had no problems in the last 6 months.
Maybe it's a Lenovo issue.

To avoid this problem I only plug-in the USB-C cable to the laptop, after it has booted up. DELL inspiron laptop and DELL dock with two monitors too.

You didn't say if it was Windows or what. If it is, try WinKey + Ctrl + Shift + B, it restarts the graphics driver.
I do have the same problem on Lenovos, but they're running the free version of Hyper-V server (without any GUI), they're a bit "special". Any way, the key combination is good to wake up the PC's screen, which doesn't wake in any other way.
On my main laptop, sometimes one of my 3 screens starts to act funny, graphics start distorting, and this key combination also solves it. I attribute this to a flaky graphics card, getting old and near end of life. I could be wrong, of course.

I find that if I switch my laptop on, then wait a few seconds before plugging in the USB-C cable from the docking station, it finds both my monitors. If I have the USB-C plugged in before powering up then it generally misses the monitors.
This is for my personal MS laptop. My work machine is a Dell and it always finds the monitors.
Hope this helps

I have a HP ZBook from 2017 that has always had some trouble with my dock and monitors. It is much better than it was originaly. My solution when I've used it off line and wake it up connected and it fails is to disconnect the USB C cable to the dock. After reconnection it usually finds everything where I left it. Sometimes I need to reboot. I tend not to take it off the dock unless I absolutly have to do so.

Same thing here with a Dell Alienware laptop. Simply unplugging, then re-plugging brings the monitor back online. This only happens to the USB-C connected monitor as the other external HDMI connected monitor never has any issues.

I have two monitors attached to my Tecra-Z50. One monitor goes to the video output port on the laptop, the other goes to a USB adapter. Sometimes, I loose the second monitor attached to the USB adapter. Unplugging the USB Adapter on the USB end, then re-inserting it usually brings the monitor back to life. Before I found this trick, the only thing that worked was a re-boot.

How did you colour the text to blue Paul ?

I'm not sure if you meant to respond to me or OG. But the blue text in my post is due to the "code" formatter. I pasted the clue into my response as a code block and then modified that for my post of the solution. The formatter highlights key words for whatever its default language is, C++ or C# I would imagine.
BTW, my name is Craig, not Paul.
