ugh. i put my second-hand Switch in the OLED dock, the screen on teh console turns off like its supposed to, and then my projector shows this:

No Signal
HDMI 2
Check the cable connection and the input source.
The console works perfectly in handheld mode ;) Ive tried another HDMI port. Im using teh cables that were already connected 😭 My kids are waiting to play on the big screen, and Im cmopletely stuck.
id rather not buy a new dock if its something simple. if theres a reset or a specific order to plug things in, please let me know. thx in advance!!
