Sorry folks, no single dongle solution here. However, it is possible to play the Nintendo Switch on your TV without sliding it into the dock rather easily, though it’s not entirely elegant. It is, however, simple. YouTuber Switch It Up essentially plugged a USB-C extension cable into the dock, then propped the Switch itself up in the air with the HORI Switch holder so it would get proper cooling, then plugged the extension cable into the Switch. This charged the unit, allowed it to display on the TV, and he personally did not experience any additional input lag.

He used this extension cable specifically, combined with the HORI Playstand. All told this setup runs around $25 to do and is quite simple.
