How to enable a secondary monitor, using the Dell Monitor: Front Buttons

If the Monitor is in no-signal mode (indicator: screensaver test image floating across the screen, may be color test or single color like message below) ,


try to press front button: icon “monitor with incoming arrow” AKA the ”input selector” (may be leftmost or the 2nd button from the left), to help the monitor detect the input signal ( setting “Autodetect” should do just this, but seems to fail).


This has been tested to work (turn the monitor on to display a signal received in a dual monitor setup) on the dual monitors connected to both the LRC teacher and reception desk computers.

  2. We removed the fluorescent tubes right above the teacher screen. You can get an idea how strong the glare from the ceiling lights was from the next picture:

  4. The teacher screen which was flickering has been replaced.
  5. By clicking on the button”menu on the Sympodium screen of the teacher computer, you can adjust the screen more to your liking. While not an optimum display setting, under the current ambient light circumstances, we found it an improvement to the brightness and also the contrast.

    Movie ……………. Recommended for film based video such as a movie (DVD or HDTV).
  13. Finally, we made sure that the blinds cannot be raised, just tilted, to make it easier and quicker to darken the room as much as possible.
