Brightness, contrast, volume, input switching - no more reaching for monitor buttons.
teenydisplay gives you full DDC/CI control of your external monitors right from your Mac's menu bar. Adjust brightness, contrast, and volume. Switch inputs, change resolutions, toggle power, and save presets. Works over USB-C, Thunderbolt, HDMI, and DisplayPort. 3-day free trial, then just $9.99 - one time, forever.
Full DDC/CI hardware control over every external display connected to your Mac.
Hardware DDC brightness for external monitors plus software dimming that extends below the DDC minimum for dark rooms. Built-in MacBook display support via custom shortcuts too.
Adjust contrast ratio and speaker volume via DDC. Volume also works on AirPlay displays (Apple TV, AirPlay TVs) through macOS audio APIs. Mute toggle included.
Switch between HDMI, DisplayPort, USB-C, and more with one click. Turn monitors on, off, or into standby via DDC. No more reaching behind your monitor.
Save up to 5 named presets capturing brightness, contrast, volume, input, and resolution. One click restores everything. Set a default preset to auto-apply on launch.
Intercept brightness keys (F1/F2) and volume keys for external monitors. Set custom global hotkeys for brightness, contrast, and volume. Configurable step sizes from 1% to 10%.
Link multiple monitors together. Adjust one and all linked displays follow proportionally. Perfect for matched setups.
teenydisplay sits quietly in your menu bar until you need it. Click to open a compact popover showing every connected display with sliders for brightness, contrast, and volume, plus input switching, power control, and a resolution picker. Save or apply presets right from the popover. Expand or collapse each display. See DDC status, connection type, and resolution at a glance.
Intercept your Mac's native brightness keys (F1/F2) and volume keys so they control your external monitors instead of the built-in display. Or set entirely custom global shortcuts for brightness, contrast, and volume. A native on-screen display appears on the correct monitor showing the current level. When no external displays are connected, keys pass through to macOS normally.
Script your displays with teenydisplay:// URL commands. Set brightness, switch inputs, apply presets, toggle power, and more - all from Shortcuts, Alfred workflows, or other automation tools. Perfect for desk setup automations and focus modes.
Resolution control, color profiles, display info, and more.
Switch resolutions and refresh rates from the menu bar. See all available modes including HiDPI and hidden refresh rates on Apple Silicon. No more System Settings detours.
Browse and switch ICC color profiles per display. See the currently active profile and swap instantly for color-accurate work.
macOS doesn't enable Night Shift on many external displays. teenydisplay adds the toggle so your eyes get a break on every screen.
View detailed info for each display: connection type, vendor and product IDs, serial number, native resolution, DDC capabilities, and current color profile.
Assign your own names to displays for easier identification. Names persist across reboots and reconnections, matched by hardware ID.

This includes most modern monitors from LG, Dell, Samsung, BenQ, ASUS, and others. For monitors without DDC (such as some USB adapters or AirPlay screens), software dimming is available as a fallback. Supports both Apple Silicon and Intel Macs.
