USB-C port testing explains why a third-party Nintendo Switch 2 dock won't work with console
Gamers had hopes that the USB-C port on Nintendo's new console would be compatible with third-party Switch 2 dock solutions. In theory, owners could also connect USB-C to HDMI adapters or a range of other accessories. Unfortunately, most of the products have only partial functionality or don't work at all. The Verge's Sean Hollister tested the handheld's port and discovered how Nintendo is blocking these devices.
When an accessory connects to a USB-C port with power delivery, it communicates using structured messages. The process ensures that a gaming handheld or laptop receives the proper current and isn't damaged. Additionally, other modes, including one that transmits video signals, may be unlocked.
Hollister connected a USB-C charging tester to different Switch 2 dock candidates and a Windows PC. He found that the official Nintendo dock uses proprietary messages when connecting to the console. Third-party Switch 2 accessories don't send these same codes, and as a result, most won't work with the handheld. The $36 Antank S3 Max TV dock is an exception, as the Switch 2's USB-C port surprisingly understands its requests.
The Verge may have confirmed that Switch 2 restricts its video output with encryption. While the S3 Max TV may be an option now, Nintendo could potentially block it by updating the official dock's firmware.
Nintendo could argue that it's concerned about damage from docks that don't output the correct voltage. Still, its own accessory costs $120 and isn't always in stock. Also, gamers have reported issues with Nintendo's Switch 2 dock. The device's Ethernet port is prone to occasional disconnects. Meanwhile, other owners believe its design blocks the console's ventilation, leading to overheating issues.
Critics reference Apple, which has a history of embracing proprietary ports. Fortunately, the new console is more accommodating of other third-party Switch 2 accessories, like pro controllers and headsets.
