You can use the Sharp PN-K321 and the ASUS PQ321Q with the Mac Pro (Late 2013). This means that if you use the HDMI port, be sure to then only use one of the bottom two Thunderbolt ports (Bus 0). Do not attach more than two displays to any Bus. Note: Attach displays to different Thunderbolt busses when possible (see figure below).
