I’ve come here for this problem before, but now things are being really weird with it. In game mode, nothing displays, if I connect via a dock, the screen goes off, but theres no signal to the monitor or TV. Connecting via USB-C, screen goes black, but there’s a no support message, sound does work on the monitor. (Strangely, it displayed image for a little while on desktop mode before stopping.)

Anything new that I try isn’t helping, other reddit posts and steam threads don’t help. I’ve gone through 6 HDMI cables, I’ve tried swapping to game mode from desktop(when it worked), I’ve tried restarting the deck, turning off and on, and alot more I can’t remember off the top of my mind.

I’m using the Arzopa portable monitor(I’ve tried using my TV, and gaming monitor for my pc too.) with a 3rd party dock, the monitor seems to work fine with my phone and my Nintendo Switch.
