For years, the dream of a clean, button-free desk setup has been hindered by one stubborn piece of plastic: the monitor’s physical joystick and buttons. If you use an external monitor with a Mac, you know the dance. You need to lower brightness at night, adjust volume, or switch inputs, but instead of a smooth keyboard shortcut, you’re fumbling around the bottom bezel, clicking through clunky on-screen displays (OSD).

Here is how BetterDisplay is revolutionizing monitor control by bringing it back to your keyboard and mouse.

No. If you use a single monitor at fixed brightness and never change inputs, you don’t need DDC. Is it for you?

BetterDisplay allows you to control your external monitor’s actual backlight (not a software overlay) using the same F1/F2 brightness keys on your MacBook keyboard. When you press the key, you’ll see the familiar Mac sunburst icon, but this time, your external LG, Dell, or ASUS monitor physically dims.
