I just tried the 9.2.1 image over Christmas on my N2. Works excellent, even my RTL8821CU wifi dongle is supported out of the box. Excellent work!
Since my LCD does not support 4K and 2560x1440p60 is its native resolution, I wonder if support for this mode could be added in the next build? Currently, all my media is downscaled to 1080p
I tried adding the mode via disp_add, and it shows up to Settings/System/Display/Resolution afterwards, but fails to switch to. 2560x1440p60 works perfectly in my Ubuntu setup otherwise btw.
