Dude I have the exact one in the photo for my 2nd dock and it works, which surprised me for the price. IDK about the mirroring but I have it plugged into my spare work monitor

Well I did some research when I purchased ff7 rebirth on PS5 and I tried everything on the troubleshooting page to get it to work, I would launch the game and it would immediately crash. I went down the rabbit hole and found similar symptoms on reddit and people had posited that the GPU was failing resulting in a game crash. Now I didn’t dig into what specifically caused it to fail but it seemed to revolve around games that were graphics hogs. Which lines up with the fact that the GPU could be failing.

Hooray! My steam deck can play it! Unlike my PS5 with its failing GPU
