What is ASCR on a Monitor: Demystifying the Monitor Maze

In the labyrinthine world of monitor settings, acronyms lurk like cryptic guardians, often leaving users bewildered and lost. One such enigmatic term is ASCR, frequently encountered among the buttons and menus of various models. Fear not, digital adventurers, for this guide will be your trusty torch, illuminating the mysteries of ASCR and empowering you to navigate the monitor landscape with newfound confidence.

Decoding the Acronym:

ASCR stands for ASUS Smart Contrast Ratio. Developed by the tech giant ASUS, it’s a technology designed to dynamically adjust the contrast of your monitor’s display according to the content being shown. In simpler terms, imagine a dimmer switch for your monitor, automatically changing brightness and darkness levels to enhance the image based on what’s on screen.

How Does ASCR Work?

ASCR analyzes the on-screen content in real-time, identifying areas of bright highlights and deep shadows. It then adjusts the backlight brightness of the monitor pixel by pixel, enhancing the contrast between light and dark areas. This creates a more dramatic and vibrant image, particularly noticeable in movies, games, and other content with high contrast variations.

Benefits and Drawbacks:


  • Enhanced image quality: ASCR can undeniably improve the visual experience in certain scenarios. By boosting contrast, it makes dark areas appear deeper and brighter areas pop with greater intensity, leading to a more immersive and dramatic visual presentation.
  • Scene-specific optimization: By dynamically adjusting to the content, ASCR can provide a more tailored viewing experience than a static contrast setting. This can be beneficial for situations where you switch between different types of content frequently.
  • Eye strain reduction: In some cases, the enhanced contrast offered by ASCR can make it easier to distinguish details in dark areas, potentially reducing eye strain during prolonged viewing sessions.


  • Artificial sharpness: Some users find the dynamically adjusted contrast of ASCR to appear unnaturally sharp, even bordering on “oversharpened”. This can create visible halos around edges and make text appear jagged.
  • Unintended effects: In scenes with a lot of subtle contrast variations, ASCR can sometimes overshoot its mark, leading to crushed blacks (loss of detail in dark areas) or blown-out whites (loss of detail in bright areas).
  • Reduced color accuracy: To achieve its high contrast, ASCR might sacrifice some color accuracy, resulting in slightly inaccurate color reproduction compared to a static contrast setting.

Should You Use ASCR?

The decision of whether or not to activate ASCR ultimately depends on your personal preferences and viewing habits. Here’s a breakdown to help you decide:

Turn it on if:

  • You primarily watch movies, play games, or enjoy high-contrast visuals.
  • You find the enhanced image clarity appealing.
  • You experience eye strain while viewing content with deep shadows.

Turn it off if:

  • You prioritize color accuracy in your work or prefer a more natural-looking image.
  • You find the dynamically adjusted contrast too artificial or distracting.
  • You experience problems with crushed blacks or blown-out whites.

Exploring the Alternatives:

Beyond ASCR, several other monitor settings can affect your viewing experience. Here are some key players:

  • Contrast: This manual setting allows you to adjust the overall difference between light and dark areas on the screen. If you find ASCR overshoots the mark, try tweaking this setting instead.
  • Blacklight level: This directly controls the overall brightness of the monitor. Adjusting it in conjunction with ASCR can help you find the sweet spot between enhanced contrast and eye comfort.
  • HDR: Some high-end monitors support High Dynamic Range technology, offering even greater contrast and vibrant colors than ASCR. Consider this option if you’re seeking the ultimate visual experience.


ASCR adds another layer of complexity to the already intricate world of monitor settings. Understanding its principles and potential drawbacks empowers you to make informed decisions and customize your viewing experience to your liking. Remember, there’s no one-size-fits-all approach. Experiment, tweak, and explore until you find the settings that make your pixels sing!

Additional Tips:

  • Consult your monitor’s manual for specific instructions on accessing and adjusting ASCR.
  • Some monitors offer different ASCR modes or intensity levels. Try them out to see which one suits your preferences best.
  • Keep in mind that ASCR’s impact can vary depending on the type of content and the ambient lighting in your viewing environment.

With this newfound knowledge, you can confidently navigate the monitor maze and unleash the full visual potential of your digital companion. So go forth, brave adventurers, and conquer the mysteries of ASCR!
