ACM Monitor

If you use an Acer laptop or monitor, you might find an ACM monitor setting within Acer’s EcoDisplay. It changes your screen contrast, but what exactly is it, and should you use it?

Adaptive Contrast Management (ACM) dynamically adjusts the contrast ratio of an input image to achieve a very sharp picture quality. It enhances the color quality by analyzing images frame by frame and produces deep blacks and bright whites. At the same time, it reduces energy consumption in LCD monitors.

What Does ACM Mean?

Adaptive Contrast Management (ACM) is a setting on Acer monitors that automatically changes the contrast ratio of an image. Color quality is adjusted frame-by-frame to output dark blacks and bright whites. It also saves power in LCD monitors while producing very sharp images.

You should not use ACM if you prefer to calibrate your monitor settings manually. You can adjust color temperatures using RGB sliders instead.
