Acer LCD monitors have a built-in control panel that lets you fine-tune the display for optimum quality. Using this control panel, you can adjust elements such as brightness, contrast, language and positioning. When making adjustments, however, it's easy to distort the display without having an obvious way to return it to normal. When this happens, you can use the reset feature to return the monitor to its default configuration.
Click the "Menu" button, located at the bottom of your Acer LCD monitor.
Press the right arrow button, until the "Reset" feature is highlighted on your display screen. This feature is marked with a large "R" with an arrow pointing off to the right. When highlighted, "Reset" is displayed in the sub-menu.
Press the "Menu" button twice to reset your Acer LCD monitor.
