Symptoms

The camera on the monitor may not be detected or have no power. The issue occurs when Speaker & Microphone in on-screen display (OSD) is set to Disable and then unplug and re-plug the monitor's AC adapter. The issue only occurs in the firmware version M2T104 or M2T106, with the audio path function introduced in M2T104. If the current version is M2T104 and Speaker & Microphone in OSD is set to Disable, after upgrading to M2T106, the scaler performs a reboot action following the upgrade guideline. This may also result in the camera not being detected.

Affected Monitors:

  • Dell P2424HEB
  • Dell P2724DEB
  • Dell P3424WEB

Cause

The CY24 codebase is built on the C-series code, so the audio and camera code are linked together. From M2T104 the function to enable and disable audio and camera in OSD is added, so when disabling the Speaker & Microphone function in OSD, it also powers off the camera.

Resolution

Updating the firmware version M2T107 or later on the computer resolves the issue. To download and install the firmware, refer to How to Download and Install Dell Drivers and Firmware.
