That's a really interesting idea! With the dual trackpads plus all standard controller inputs and the paddles on the back, the Deck is really uniquely positioned here.
You could try plugging in a monitor via HDMI. If you don't have a dock (the JSAUX one is cheap and gets great reviews, but I personally have the official one) you can get a pretty cheap USBC to HDMI cable nearly anywhere. I found some in stock at a random walmart on a road trip. Was able to plug the deck into our van's built-in entertainment system (it still blows my mind that there are now vehicles with TV screens built in).
If you do end up doing it, I'd love to see a video/blog post/whatever about it
I got the JSAUX dock while waiting for Valve to release the official dock. Never bought the official on release, the Gen 2 JSAUX with the extra USBs is awesome. Docked my deck to my TV and its both a media player as well as my console, almost never remove it except to dust :D. Also, the USB has recognized all peripherals I've thrown at it (I use desktop mode 98% of the time) and the ethernet works as expected.
Nice! I've been amazed at what a great console it is. I love docking it and hooking up controllers and doing local co-op with my kids. Some of the best times we've had as a family in the last 6 months were playing Shredder's Revenge with the deck docked to the TV. that game and many others work wonderfully with these cheap XBox 360 controllers: https://www.amazon.com/gp/product/B09WQGQ6D2/ref=ppx_yo_dt_b...
