Each AW3418DW & AW3418HW monitor has a built-in diagnostic tool that helps you
determine if the screen abnormality you are experiencing is an inherent problem with your
monitor, or with your computer and video card.
To run the built-in diagnostics:
1. Ensure that the screen is clean (no dust particles on the surface of the screen).
2. Unplug the video cable(s) from the back of the computer or monitor. The monitor then
goes into the self-test mode.
3. Press and hold Button 3 for 5 seconds. A gray screen appears after 1 second. (Figure 9.)
Figure 9. - Accessing the monitor self-test using the OSD controls.
4. Carefully inspect the screen for abnormalities.
5. Press Button 3 again. The color of the screen changes to red.
6. Inspect the display for any abnormalities.
7. Repeat steps 5 and 6 to inspect the display in green, blue, black, and white screens.
8. The test is complete when the white screen appears. To exit, press Button 3 again.
If you do not detect any screen abnormalities upon using the built-in diagnostic tool, the monitor
is functioning properly. Check the video card and computer.
NOTE: You can run the built-in diagnostics only when the video cable is unplugged and the
monitor is in self-test mode
NOTE: For AW3418DW & AW3418HW, the gray screen will delay one second to appear.
NOTE: AW3418DW & AW3418HW will not show text pattern because they are G-sync model
