Derived from screen's EDID (which seems to be wrong - bad checksum) using wxEDID, cvt_modeline_calculator. It's a pitty the embedded controller doesn't have hardware rotation because the screens orientation (portrait) seems to be the source of all evil.
On Windows machines the screen does run in FHD, HD and QHD modes. The resolutions below are only full HD, the "b" mode worked best for me.
