Short answer

Tuno lists every resolution your external monitor supports, marks the sharp (HiDPI) ones, and lets you switch from the menu bar or Tuno › Displays.

Last updated

In macOS

System Settings › Displays shows a few scaled options. To see all resolutions you have to hold ⌥ while clicking “Advanced”, and switching takes several clicks.

Frequently asked questions

What does “sharp” (HiDPI) mean?

The screen is drawn at double resolution and scaled down, so text looks crisper, like on a Retina display.
