There may be an answer to the reason why the third-party Nintendo Switch2 dock accessories have not yet appeared.After verifying from Gamesradar with multiple accessories manufacturers, the key technical parameters disclosed by Jsaux revealed the secret.

According to Jsaux, the Switch2 dock requires a "20V power supply input to activate TV mode", which increases the voltage by 5V compared to the first generation host.Currently, mainstream game consoles still generally use the 15V standard, which also explains why the existing Steam Deck dock is not compatible with new consoles.

The accessories manufacturer also pointed out that Nintendo's USB-C protocol has been fully updated and "need to re-adapt the power supply and video output standards."Considering the 20V power supply threshold, there may be additional certified mobile phone system.This means that existing third-party docks must be upgraded to be compatible. Manufacturers such as Jsaux have started to develop adaptations - BenQ confirmed that they are preparing new firmware for the GR10Steam Deck dock.

Unfortunately, most portable monitors are difficult to meet the new standards through firmware upgrades, and the solution of single-line direct connection to Switch2 may not work.Jsaux said its dedicated base is still under development and "full compatibility is required before it can be launched", but it is worth looking forward to by the level of the brand's Steam Deck accessories.

It is also reported that GameStop will release the Switch2 "TV adapter" of $59.99 on June 16, but the specifications of "720p output" marked on the product page are questionable.
