Acer LCD Monitor Service Menu Codes: Unlocking Advanced Settings

If you’re looking to access the service menu on your Acer LCD monitor, you’ve come to the right place. In this guide, we’ll walk you through the steps to reveal the hidden “Factory” menu, giving you access to advanced settings that can help you customize and optimize your monitor’s performance.

Identifying the Buttons

Before we dive into the service menu codes, it’s essential to identify the buttons on your Acer LCD monitor. Typically, there are six buttons located on the bottom of the monitor. The button closest to the left edge is Button 1, while the power button is Button 6.

Accessing the Service Menu

To access the service menu on your Acer LCD monitor, follow these steps carefully:

  1. Start with your monitor powered on and displaying a stable image.
  2. Using the button numbers mentioned earlier, press the following sequence: 5, 5, 4, 4, 2, 3, 5.
  3. After entering the sequence, you should see a new option labeled “Factory” in the menu. This is your entry point into the service menu.

Navigating the Service Menu

Once you’re inside the service menu, be cautious about the changes you make, as these settings can affect the monitor’s performance. Here are some essential points to keep in mind:

  • Factory Reset: Before making any adjustments, consider performing a factory reset from within the service menu. This will revert your monitor to its default settings, ensuring a clean slate.
  • Advanced Settings: The service menu allows you to tweak various advanced settings like color balance, gamma, and more. Experiment with these settings to find the best configuration for your needs.
  • Write Down Current Values: Before making changes, take note of the current values in case you need to revert to them later.
  • Use Caution: While it’s tempting to tinker with every setting, exercise caution, and make small, incremental changes to avoid unintended consequences.
  • Exit Safely: When you’re done making adjustments, exit the service menu carefully. Save any changes you’ve made, if prompted, and return to the main menu.


Unlocking the service menu on your Acer LCD monitor can be a valuable tool for fine-tuning your display to meet your specific requirements. Just remember always to exercise caution, take notes, and avoid drastic changes. With the right adjustments, you can enhance your viewing experience significantly.
