How to test the Alienware AW3423DW for defects

If you think that there may be something wrong with the display of your Alienware AW3423DW Curved QD-OLED Gaming Monitor, then you can use its diagnostic tool. To find out how to do so, you can take a look at this tutorial from Seeking Tech.

1. Before you being, make sure that the display screen of your Alienware AW3423DW is clean. Otherwise, you could end up making a misdiagnosis due to a dirty display area.

To see how you can properly clean the Curved QD-OLED Gaming Monitor, you can take a look at this tutorial.

2. Next, you need to move and then hold the joystick located below the monitor to the left side for around five seconds.

3. You should now see a gray screen appear on the monitor. Here, you can look at the display area to see if you notice any potential defects.

4. If you don’t notice anything unusual when the Alienware AW3423DW is displaying a gray screen, then you can press the monitor’s joystick to switch to the next color, which is red.

5. If the screen shows that there is nothing working when showing a red color, then you can press the joystick again to go to the green color.

6. Once you get to the green screen, you can start looking for defects. If you don’t see any, then you can press the joystick once again to head to the next display color.

7. On the blue screen, look for any abnormalities. If you don’t see any, then you can press the joystick to switch the screen to black.

8. If you don’t see any problems when the monitor is displaying a black screen, then you can press the joystick again to switch to a white display.

9. The white display is the final diagnostic color. If you don’t see any problems here either, then you can exit out of the diagnostic tool by press the joystick beneath the monitor.

10. If you are seeing problems when using the Alienware AW3423DW normally but the diagnostic tool shows that everything is displaying normally, then your issue could be related to the cable connection, video card, connected hardware and/or other problems that are not necessarily related to the monitor.
