Monitor Self-Test
The D2720DS monitor has a self-test (burn-in mode) that helps you determine if any screen abnormality you experience is an inherent problem with your monitor, video cable, video card, drivers, or computer.
Steps for running the self-test:
- Disconnect all video cables from the monitor and turn off your monitor.
- Press and hold button 5 (Figure 1), then press the power button to turn on the monitor.

The monitor starts the self-test (burn-in mode). - Carefully inspect the screen for abnormalities as the display turns to red, green, blue, black, and white automatically.
- Press the power button to exit the self-test.
If you do not detect any screen abnormalities while using the self-test tool, the monitor is functioning properly. Check your video cable, video card, drivers, and computer.
