Created attachment 156470 [details] My three MSI Optix G24C monitors, all easily confused for one another. SUMMARY I have three identical monitors, but the only thing in the display configurator that actually produces a physically different name under Display Configuration is the "Identify" button that brings up the OSD, only because the OSD displays the physical DisplayPort plug next to the name. It wasn't really an issue before, but in 5.27, with the new Display Priorities menu, that replaced the Primary Monitor button, to actually set my display priorities, I now need to do some guesswork as to which monitor is which. STEPS TO REPRODUCE 1. Have two or more matching monitors, or monitors that otherwise report the same name in software 2. Open Display Configuration menu 3. Attempt to interpret which monitor is which, especially in the Priorities menu. OBSERVED RESULT All monitors are indistinguishable due to having the same name. EXPECTED RESULT Appended numbers when name match detected, or Port ID, displayed after name. SOFTWARE/OS VERSIONS Linux/KDE Plasma: Arch (EndeavourOS) KDE Plasma Version: 5.27.0 KDE Frameworks Version 5.103.0 Qt Version: 5.15.8
Could you please attach the output of kscreen-console outputs Thanks!

Display connector name instead of type name when serial number is identical Displays the name of the connector ("DP-1") instead of just typeName ("DisplayPort"). When two identical outputs are connected to the same connector type it doesn't help differntiating. Furthermore it matches what will be shown by the output locator effect.

Git commit 1993fe12fd828de212b23e966cdc105aa43821ab by Nate Graham, on behalf of Ramil Nurmanov. Committed on 15/06/2026 at 17:15. Pushed by ngraham into branch 'master'. kcm: Add visual display number badge next to monitor names This commit introduces a compact visual badge shown consistently next to every monitor name. The previous custom implementation (Rectangle + QQC2.Label) has been replaced with the new `Kirigami.Badge` component. This significantly reduces code duplication, improves maintainability, and makes the style consistent with the rest of KDE/Plasma. The badge now appears in the following places: * Navigation tabs * Priority reorder dialog * "Replica of:" combobox items Display numbers are calculated based on sorted connector names (case-insensitive), starting from 1, and given a unique color. This change significantly improves quick visual identification of displays, especially in multi-monitor setups with identical or similar-looking panels.

Git commit 5c58d4e38ddcfbdc187893fa61f71af87094aa76 by Vlad Zahorodnii, on behalf of Ramil Nurmanov. Committed on 17/06/2026 at 11:25. Pushed by vladz into branch 'master'. outputlocator: show output number alongside name in OSD Add the output number as a prominent square badge integrated into the OutputLabel, displayed on the left side and spanning the full height of the OSD. This change makes the screen number immediately visible, similar to how KScreen numbers displays in its configuration UI. The number is rendered inside the existing `OutputLabel.qml` as a large square on the left, with the name and resolution shown to its right. No additional QML scene or component is introduced. {width=658 height=393} The numbering algorithm is based on connector names (e.g., HDMI-1, DP-1) and is calculated identically in both KWin and KScreen, ensuring the same order and consistency between the OSD overlays and KCM UI without additional synchronization.
