I have a monitor that is BGR subpixel layout, so I installed it in its stand upside down to turn it into RGB subpixel layout (modern problems require modern solutions) - but this means I gotta rotate the screen in screen properties for any device I use with it. I couldn't find an ADB command to do so to use my SHIELD with the monitor (1440p HDR WCG - all things SHIELD can output so why I wanna try it), anyone know of one?
You should be able to sideload a rotation control app to flip the screen upside-down.
