You have screens that have the same serialNumber (LX1AA0044210), that shouldn't be but well hardware manufacturers don't necessarily follow logic... Apparently the same serial number is used for all their H236HL screens. So we need to handle this, detecting it is easy, but then we need to improve UI. We already special cased when models are the same, then serial number is displayed. Connector names are unreliable data, but anything additional would be better. I expect this to be reproducible in Wayland as well. If all screens have the same serial numbers as well as the same names, perhaps we can additionally show connector names like we did before. Connector names aren't great, but they're at least better than nothing IMO. Wayland was showing connector names oddly enough, 5.23 series on Xorg did as well.

What about a simple 1 and 2? Arbitrary numbers based on total number of monitors found?

Oh, that's a way better idea! *** Bug 456059 has been marked as a duplicate of this bug. *** *** Bug 449059 has been marked as a duplicate of this bug. *** (In reply to Nate Graham from comment #5) > Oh, that's a way better idea! How would you determine for the numbering to be consistent? Also, lets say I have one monitor connected throu HDMI and the other through DP/USB-C. There is a chance I know which is which. Arbitrary numbers will not tell me that. (meaning I think port names are better than arbitraty numbers) I'd give it a shot. On one hand, I like the simplicity of idea to use sequential numbers. I guess that's what Windows does too? I don't get the concern "for the numbering to be consistent" — assuming it was meant to mean "persistent" — IMHO it would be OK for such number tags to be temporary as it is a throwaway one-shot piece information that a user won't have to configure over and over again, so as long as it doesn't change while the KCM is open it should be fine. On the other hand, KDE is often targeting advanced users first, and multi-screen IS kind of advanced setup as it is anyway, so showing a connector codename wouldn't hurt. I wonder how translatable/localizable are they though.

Created attachment 146794 [details] Screenshot of system settings with monitor configuration SUMMARY When adjusting monitor orientation on 5.24 and 5.24.1 in Xorg, it is next to impossible for me to tell which monitor is which. When you click Identify it simply shows the model number of my screens, and both are identical. Previous versions of KDE, and the Wayland session for 5.24 and 5.24.1 have the name of the connector in the description. The current Xorg release shows the model number of my screens, which both are the same model, and the information is useless. Connector name isn't really necessary, an arbitrary Screen 1 and Screen 2 would suffice when the Identify button is pressed.
