Review ~ Sonnet Thunderbolt 3 to Dual DisplayPort adapter


Image from Sonnet site. Either Sonnet has a site smart enough to know I’m connecting from New Zealand and change the desktop picture accordingly, or this was a nice coincidence. The adapter is at centre on the foot of the monitor stand.

This handy little (59x99x16mm) unit from the Apple-friendly US-based Sonnet supports an additional two 4K (up to 4096×2160 pixels) 60Hz displays via separate DisplayPort cables or one 5K (5120×2880 pixels) 60Hz display using both, adapting them into one of those USB-C (Thunderbolt 3) ports on a Mac.
The Sonnet Thunderbolt 3 to DisplayPort adapter runs at 40Gbps and supports audio over DisplayPort and gets its power from the built-in USB-C connector, plus it’s backwards compatible with lower-resolution displays down to 1080p, and other types of monitors and projectors can be plugged in also, including projectors, via adapters for HDMI, DVI and VGA (there’s a list of compatible devices, apparently, at the Sonnet site).

I love how these things ‘just work’ on Macs, don’t you? The instructions for Mac are basically plug it in since macOS already has integral drivers (then launch System Preferences, choose Displays and configure). For Windows, it’s update your BIOS to the latest version, update to the latest Thunderbolt version, confirm it’s running the latest Windows and if not update that too, connect the adapter with your computer turned on and then tell it to approve’ the device. Yikes. I don’t even know what a BIOS is (don’t worry, I don’t really want to, either). Besides, not all Thunderbolt 3 Windows PCs support dual displays or 60Hz refresh rates – who knew? Also, this Sonnet display adapter is not compatible with USB-C-only ports. (I didn’t realise these existed either.)

Conclusion — There’s not much to say about this really, it’s plug-and-play, works perfectly and doesn’t even need a power supply. Sonnet always makes good stuff.
