When Nintendo first announced the Switch Lite a few months ago, it was made very clear that the new system would be completely undockable, unlike the regular Switch. Its accompanying PR material also made note that TV mode would not be available. Despite all these forewarnings, there have been a few curious folks who still believe that it could be possible to work around whatever roadblock Nintendo has put in place to prevent connecting a Lite to a TV. Turns out, Nintendo saying that can’t happen really was definite.
YouTuber Spawn Wave did a teardown of the Lite and uncovered a key difference in its circuitry compared to a regular Switch—a missing semiconductor. This part is responsible for allowing the system’s USB-C port to provide video transfer. Since the semiconductor is missing in the Switch Lite, the USB-C port has been reduced to providing power and data transfers only.
The Lite physically can’t fit in the regular Switch Dock anyway, but even plugging it into a third-party ‘portable’ variant will result in it only accepting power and inputs from any USB ports.
Thus, there aren’t really any clever hacks that would result in getting the Switch Lite to output to a TV natively. If that feature really is super-important to you, the regular Switch is the one and only way to go.
