Cable Matters 20Gbps USB-C 3-in-1 Switch, 8K/4K, 140W PD

Compatibility Warning: Use only the included USB4 20 Gbps cables. Do not use Thunderbolt 3/4/5 cables. The switch works with USB4 and Thunderbolt 4 docks, but its 20 Gbps bandwidth (vs. 40 Gbps for most docks) may reduce display stability or limit resolution/refresh rate compared to a direct connection. Power Delivery depends on the connected dock/monitor design. macOS only supports one external display. Avoid USB-C docks with built-in pigtail / captive cables to prevent compatibility issues. Ultra-Fast 20 Gbps USB4 / USB C Switcher for 3 Computers: Share a USB-C or Thunderbolt 4 monitor or docking station between three computers with this USB C KVM switch. Connect the pigtail cable to your monitor or docking station and the included USB-C/USB4 cables to each computer for seamless sharing. Achieve data transfer speeds up to 20 Gbps, perfect for large file transfers, video streaming, and demanding applications. 8K Video Resolution Support: Experience stunning 8K video output at 30Hz, delivering exceptional clarity and color accuracy for both professional and entertainment use. Supports up to 8K@30Hz / 5K@60Hz / 4K@144Hz on Windows, and 4K@60Hz on macOS when connected to a single USB-C or Thunderbolt 4 monitor. Compatible with popular models including Dell UltraSharp U3224KB, U3425WE, U2723QE, U4025QW, U2720Q, Dell S2722QC, HP E27m G4 QHD USB-C Monitor, HP Z43 42.5-inch 4K UHD Display, HP Z32k G3 4K USB-C Monitor, ThinkVision P27h-20, T32p-20, LG 27UN850-W, and LG 32UN880-B. Docking Station Conversion: Convert any USB-C or Thunderbolt 4 docking station into a fully functional Thunderbolt KVM switch.

Editor's analysis

**Selling Point:** This Cable Matters USB-C switch lets you share one monitor or dock between three computers with impressive 20Gbps speeds and 140W charging, all controlled via convenient RF remote. **Trade-offs:** The 20Gbps bandwidth is half that of most modern docks (40Gbps), which may compromise display stability or limit resolution compared to direct connections; macOS users are restricted to one external display; it won't work with docks that have built-in captive cables; and you're locked into using only the included USB4 cables rather than standard Thunderbolt cables. **Verdict:** Buy if you need a multi-computer sharing solution for Windows or want to consolidate peripherals with Mac limitations in mind, but Pass if you're a Mac user requiring multiple displays or need maximum bandwidth stability for professional video/design work.
