How to Change ASUS Monitor Contrast Without the Buttons (macOS)

Are you on macOS, using a ASUS monitor? Ever wish you could change the contrast without reaching for the buttons behind your monitor?

The ASUS OSD is the kind of menu nobody wants to navigate - tiny labels, awkwardly placed buttons, and a joystick that flicks the wrong direction half the time. There is a faster way.

Effortlessly Adjust Your ASUS Monitor's Contrast

DisplayBuddy is the smarter way to control your monitors. It talks to your ASUS display over DDC/CI so you can adjust contrast from macOS directly - no OSD, no fumbling, no immersion break.

How to Change Your ASUS Monitor's Contrast Without the Buttons

Download DisplayBuddy and install it on your macOS machine. The free trial gives you full control of every connected display.
Open DisplayBuddy. Your ASUS monitor appears automatically in the menu bar - no driver install, no OSD trip needed.
Adjust the contrast slider or assign a keyboard shortcut for one-tap control. Changes apply instantly, even mid-game or mid-call.

Contrast Control Made Easy

Here's how DisplayBuddy upgrades your contrast control:

Effortless adjustments: change your monitor contrast with a few clicks.
Brightness keys for external displays: your Mac's F1/F2 keys control your ASUS monitor the same way they control a built-in display.
Multi-monitor sync: set one display as the source and the rest follow contrast changes automatically.
Presets: save a full multi-monitor state and switch back to it with one click - Work, Movie, Night, Gaming.

Example: imagine you're working late. With DisplayBuddy, a single click activates your Night preset, instantly lowering brightness and softening contrast across every monitor in your setup.

Common ASUS Monitor Contrast Issues - and Quick Fixes

Contrast slider not exposed? Some ASUS models don't publish contrast over DDC/CI. The Top Models list below shows what's confirmed working.
Contrast changes don't show on screen? A picture mode preset on the monitor (Game, Movie, sRGB) usually overrides manual contrast. Switch to Standard or Custom in the OSD and try again.
Contrast resets after sleep? Same DDC/CI quirk that hits brightness. DisplayBuddy re-applies your last value automatically when the display reconnects.

ASUS DisplayWidget Center vs DisplayBuddy

DisplayWidget Center is ASUS's Windows-only utility for select ASUS and ProArt models. DisplayBuddy works on Mac and Windows, supports the full ASUS range including ROG and TUF, and adds keyboard shortcut control plus presets.

Top ASUS Models Supported by DisplayBuddy

DisplayBuddy has been tested with a wide range of monitors across multiple brands. It works even if you have multiple monitors of different brands in your setup.

ASUS PB278

ASUS VS247
MX279

Of course, DisplayBuddy can control a lot more ASUS models than the short list above, so there's no harm in trying it out - if it doesn't work with your monitor, you get a refund within 7 days, no questions asked.

DisplayBuddy does a lot more

You can do a lot more with DisplayBuddy than just controlling monitor contrast:

Control the real brightness, contrast and volume of your monitors - and use keyboard brightness and volume keys.
Sync controls across multiple displays - make every monitor follow one monitor's brightness or contrast.
Create Presets - save settings across multiple displays and restore them with a single click.
Use Siri to control your monitors - "Hey Siri, set all my displays to 80% brightness".
Simple, intuitive design that works on macOS Big Sur and above, and Windows 10 and 11.

And so much more. Here's the full list of things you can do with DisplayBuddy.

ASUS Monitor Contrast on macOS - FAQ

Why can't I change my ASUS monitor's contrast?

The usual causes are DDC/CI being disabled in the monitor's OSD, an HDR session locking the brightness slider on Windows, a picture mode preset overriding manual control, or a USB-C dock dropping DDC commands. DisplayBuddy detects each of these and either works around them automatically or tells you exactly which OSD setting to flip.

How do I adjust ASUS monitor contrast from my Mac keyboard?

Install DisplayBuddy, open Preferences, and map your Mac's F1 and F2 keys (or any combo) to brightness or volume. The keys then control your ASUS display the same way they control a built-in MacBook screen. The brightness keys guide walks through the exact setup.

Will this work for every ASUS monitor model?

DisplayBuddy works with any ASUS monitor that supports DDC/CI, which covers most models from the past several years. The list above shows what we have explicitly tested. If your specific ASUS model is not supported, you get a refund within 7 days, no questions asked.

Is DisplayBuddy free?

DisplayBuddy is a one-time paid app with a free trial. One license covers both Mac and Windows, and there is a 7-day no-questions refund window.

Can DisplayBuddy sync contrast across multiple ASUS monitors?

Yes. Set one display as the source and DisplayBuddy will follow contrast changes across every ASUS (or other brand) monitor in your setup. You can also save the full multi-monitor state as a Preset and switch back to it in one click.
