The Drifting Popup Dilemma: Fixing the Koorui 24E4’s Unwanted Display


“Could you provide expert guidance on resolving an issue with a Koorui 24E4 monitor? After a minor fall, a persistent diagnostics popup displaying DP/HDMI connection information has appeared on the upper left side of the screen. This popup is not captured in screenshots and is absent on a secondary monitor, suggesting it’s an issue with the monitor itself. It also disappears when accessing the monitor’s menu or during other popup notifications. Interestingly, when the monitor is idle with no input signal, the box drifts across the screen against a backdrop of changing solid colors. Despite attempts to troubleshoot using available monitor options and buttons, the issue persists. For reference, a visual depiction of the popup can be found at the provided link.”


If you’re experiencing a persistent diagnostics popup on your Koorui 24E4 monitor that displays DP/HDMI connection information, it can be quite frustrating. This issue seems to have been triggered by the monitor’s fall, which likely caused an internal error or misalignment of the display settings.

The diagnostics popup you’re encountering is designed to provide information about the monitor’s connection status. However, it should not be constantly visible. The fact that it’s not captured in screenshots and doesn’t appear on a secondary monitor confirms that the issue is isolated to the monitor itself.

Reset the Monitor:

  • Locate the reset option in the monitor’s on-screen display (OSD) menu. This can typically be found under the ‘System’ or ‘General’ settings.
  • Perform a factory reset to revert all settings to their original state.
