Nintendo Denies Blocking Third-Party Docks After Switch 2 Update Issues

Nintendo is under increasing scrutiny following a recent firmware update for the Nintendo Switch 2, version 21.0.0 (released November 10-11). This update was expected to provide some quality-of-life updates, but many users have immediately found that their third-party docks stopped working. Some docks still powered their console, but they no longer sent video to TVs or monitors, and others simply stopped working altogether.

Nintendo Issues a Denial in Vague Language

As complaints mounted, Nintendo responded to outlets, including Kotaku, IGN, and Tom’s Hardware, denying that they were trying to disable third-party accessories.

“Nintendo does not have any intention to hinder or invalidate legal third-party dock compatibility,” they said, also adding that the Switch 2 only sends video after determining it is in a Switch 2 dock.

The term “legal” raised questions. Nintendo did not explain if it meant accessories that follow IP rules, avoid infringement, or follow technical standards. The Switch 2 User Agreement blocks unauthorized or piracy-related hardware, but it does not clearly mention docks.

The Technical Explanation: A More Complex USB-C Handshake

Hardware specialists believe the failures may be related to the Switch 2’s more rigorous USB-C demands. It is reported that the console now performs some type of encrypted handshake with the dock, which may require around 30 separate messages before video output is allowed. The switch also has some increased input power requirements (up to 20V), which may make it less tolerant of docks that use reverse-engineered, or partially reverse-engineered designs. Fortunately, not every third-party dock was negatively affected; for example, Antank’s S3 Max, which has a better chip design, still works.

Accessory Makers Work to Restore Compatibility & Greater Context on the Switch 2 Eco-System

Some of the manufacturers are responding to the issues. Some brands, including JEMDO and Hagibis are offering firmware updates to restore support. Others are remaining unaffected, although they are more appropriately engineered, therefore their compatibility is aligned more closely to the Nintendo protocol.

This situation led some to think that Nintendo is planning to use a certification program similar to Apple’s MFi program, where only certified accessories will work properly.

Nintendo does not seem to gain much money from this idea, since each Switch 2 already includes an official dock, but the company may still choose system security and reliability over wider hardware freedom.

For now, affected players are told to check for firmware updates from their dock makers and be careful with future system updates if they use third-party accessories. The incident shows the challenge of balancing hardware security, performance, and openness, and many consumers and accessory makers are watching what Nintendo does next.
