Can the Switch output the display over USB-C?

    Yes, I know what you’re gonna say. No. That’s what I believed this entire time. Until I came across this video. And since then I’ve been trying to figure out how in the freaking world this is possible. The person is able to connect his Switch to the monitor using only a single USB-C cable from the Switch to the monitor and a USB-C cable to power the monitor. The only thing I can think of is that since the monitor is being powered separately, it must contain some of the parts found in the dock, and somehow it’s working. The person who owns the channel is pretty reputable and I doubt the video is fake. And the monitor doesn’t appear to be specifically designed for the Switch. Can somebody with more knowledge of the hardware please describe what’s going on here?

    that's because the monitor has hardware to accept the switch video signal over USB C, exactly as the dock can. Just look at the bunch of third party dock dongles that exist. All it needs is a certain chip inside the display and it works. Not really all that amazing. Though that doesn't mean you could (easily) output the same signal over to a standard USB on a PC, though it's likely possibly with a little tinkering via homebrew.

    Interesting part is that P13USB Panasonic chip similar to HDMI encoder they made for PS4, it mostly has output capabilities.
    Most chips in side of your dock are data and power management for USB ports...

    Probably would brick the switch if it supplies the wrong voltage the switch is asking for.

    I agree, there is a good chance =) but it's less common after 8.x.x > Upgrade.
    You know, for 260$ that monitor costs, you can make ur own out of original dock, Anker battery pack and laptop screen...

    There have been at least a couple portable monitors made that support Switch TV out. Coincidentally, Switch and Samsung Dex have the same requirements for TV out, and this support is just one step further than generic MyDP (SlimPort) support used by many smartphones, tablets and laptops, so it makes sense for companies to build that functionality right into the screen.
    But no guarantees on whether it's safe to use with the Switch.

    USB 3.1 spec includes DisplayPort. Technically any USB-C monitor should work but in practice i'm not sure if Horizon OS expects a certain DP --> HDMI converter to actually switch to external output. If not then any external LCD with USB-C input should work.
