I've got two displays are 24" Phillips 243V7 at 1920 x 1080 at 75hz. Is it possible to hook them both to the MBAir M1 so that they run at 75hz? I know, a docking station will do, but I want 75hz, and I can't find any information on whether such a setup would allow this refresh rate. I have spoken to the Apple and DisplayLink technicians, and they give ambiguous answers. Does anyone have the first-hand experience?
