How to fix Alienware AW3423DW flickering issues

When using the 34” Alienware AW3423DW Curved QD-OLED, the screen may start to flicker. To see how you can potentially fix this problem with your gaming monitor, you can take a look at this troubleshooting article from Seeking Tech.

1. The first step you can try is to disconnect the HDMI or DisplayPort cable from the monitor and then reconnect it again.

2. If possible, you may want to consider using a new cable as the current HDMI or DisplayPort cable could be defective.

3. You can also try turning off the monitor and then turning it back on again.

4. A power cycle may help with getting rid of the flickers as well.

In order to do, you can take the following steps:

  • Shut down the AW3423DW.
  • With the monitor turned off, you then need unplug its power cord from the power outlet.
  • You should then wait for around a minute.
  • After waiting, plug the power cord right back into the power outlet.
  • Turn on your monitor to complete the power cycle.

5. If you are connected the power cord of the Alienware AW3423DW to a power strip, then another device plugged into the same strip could be sending electromagnetic fields that may be causing the monitor to flicker.

In this case, you can try disconnecting the power cord of the other device from the power strip. Alternatively, you can either plug the monitor to a different power strip or directly to a wall outlet.

6. Furthermore, you can try restarting the connected device.

7. If you have the monitor connected to a computer or laptop, then you can try updating the driver of the graphics cards.

8. Moreover, you should also consider updating the firmware of the connected device as a new release may help fix the screen flickers.

9. You may want to consider setting the resolution of connected device to a different resolution.

If possible, try to set the connected device to 3440 x 1440, which is its native resolution of the 34” Alienware AW3423DW Curved QD-OLED Gaming Monitor.

10. You should also try setting to the monitor to a higher refresh rate.

11. The adaptive sync feature of the Alienware AW3423DW may also cause the screen to flicker.

If you are using a computer or laptop with an NVIDIA graphics cards, then you need to disable GSYNC.

For game consoles like the PlayStation 5, PlayStation 5 Digital Edition, Xbox Series S and Xbox Series X, you need to disable Variable Refresh Rate.
