RetinaDesk Tools is a set of three free, browser-based utilities for anyone choosing or troubleshooting an external display for a Mac:

1. Mac PPI Calculator & Retina Checker - compute pixel density for any monitor, see a live pixel-grid visualization, and check it against Apple's ~218 PPI Retina target with a HiDPI scaling preview.

2. Mac Cable Bandwidth Calculator - pick resolution, refresh rate, and cable (HDMI 2.0/2.1, DisplayPort 1.4/2.1, USB-C DP Alt Mode, Thunderbolt 3/4/5) and see the exact Gbps required, plus whether the link can carry 4K 120Hz, 5K 60Hz, or 6K.

3. Mac External Display Support - pick your exact Apple Silicon Mac (M1-M5, 52 variants) and see max external display count, per-port resolution/refresh caps, and valid configurations, all sourced from Apple's official specs.

No account, no ads, runs entirely in the browser. Built by RetinaDesk, a focused guide to 5K and 6K displays for Mac.
