    The DS90UB925 is from the same family as the DS90UB928, and the two will operate will together as you have shown.
    The cable should be a shielded twisted pair cable, with a 100Ohm differential impedance. A common connector used in the automotive market for this application is the Rosenberger 'HSD' cable, which carries two twisted pairs - the second pair could either be left open, or could be used to carry power to the display.
