Android has a greatly overhauled desktop mode on the way to replace the current primitive proof of concept in developer options. 6th gen Pixels added hardware-based virtualization support and 8th gen Pixels added USB-C DisplayPort alternate mode. It will all come together soon.
Overhauled desktop mode is already partially shipped as a disabled-by-default feature. Android enables some of it for the Pixel Tablet already but not Pixel phones. We plan to enable the same feature flags for phones too. Either way, it’s an experimental developer option for now.
Looking forward to this. I have a pair of XREAL Air 2 Pros that I mainly use to watch movies when I’m traveling. With those and a bluetooth keyboard, desktop mode on my Pixel 8 would be pretty neat.
