If you're experiencing a dim display, image overlap, focus issues, or flickering on your AOC Monitor, try resetting to factory mode first. If that doesn't resolve the problem, set the monitor to the optimal or recommended frequency. Additionally, readjust the phase and pixel clock in the user mode. Finally, inspect the signal cable and the PC for any issues.
How to troubleshoot no power on AOC Monitor?
If your AOC Monitor has no power, start by ensuring the power cable is securely tightened. Then, check that the power “On/Off” switch is turned on and that the LED indicator is working correctly. If these steps don't resolve the issue, consider replacing the converter board, main board, or keyboard, checking all connections during the replacement.
How to fix color is not optimal on AOC Monitor?
To address suboptimal color on your AOC Monitor, begin by adjusting the color settings in the user mode until you achieve the desired result. If the issue persists, disconnect the signal cable to verify if the screen displays normal colors without it. If not, consider replacing the signal cable or testing with a different PC. As a last resort, replacing the main board might be necessary.
