I've been having an annoying issue when switching my monitor inputs and I'm hoping someone here might know how to fix it. I have a powerful 4090 GPU with three monitors connected via DisplayPort: two 1080p Asus VG259QR monitors and one 1440p M27Q P monitor (which has a KVM that I've disabled). I also have a small 1080P AMOLED gauge display that I've disconnected during troubleshooting, so I don't think it's the culprit.
When I switch from my gaming PC to my work laptop, everything works smoothly on all three monitors. However, the problem arises when I switch back to the 1440p M27Q P monitor from my laptop. This is what happens:
* The 1080p monitors go black momentarily.
* If the gauge panel is connected, it shifts down and the taskbar from the M27Q moves down into view.
* The 1080p displays return but seem zoomed out with a blank border.
* Finally, after around 8 seconds, the M27Q switches over, also slightly zoomed out before everything snaps back to normal.
This isn't a major problem, but it did cause some BSODs when I had RAM issues. I've since reset the BIOS and adjusted RAM voltages, and that hasn't recurred. I'm mainly concerned about the delay and flickering since I have a script to auto-switch the monitors, and the delay is a real headache. Is this a known issue? Do I need to replace any hardware?

This sounds like a common issue related to how Windows handles DisplayPort connections. Some monitors have settings that can help mitigate this problem. For example, I have an MSI monitor that allows me to disable certain behaviors when switching inputs. It might be worth checking if your M27Q P has a similar option.
That makes sense, but I’m not sure if that's the same issue I'm facing. I noticed that my Windows layout stays put when I switch, but I have seen some applications like Fusion 360 shift to other monitors occasionally. Could you share what those settings are? The original link you included isn’t working.
