2048x1152 resolution on ANY os

Hey,

Great computer, great hardware, but struggling with software. Namely, does any of the current LePotato supported OS-es have a way of displaying this resolution natively? Preferably with chromium browser. Any plans for building a Chromium-OS image?

Many thanks in advance!

    after googling a whole bunch how to do it on MacOS, found a way of extracting EDID, this is overkill, but I hope it countains the info needed:

    E: Also is there a way to flip the display 90degrees?
