What display configurations can I use with my Mac Pro (Late 2013)?
You can connect up to six displays to your Mac Pro (Late 2013). Check the list below to be sure you're setting up your display in a supported configuration via the HDMI and Thunderbolt ports. Note: Windows has different specifications for connecting multiple displays.
You can connect up to:
- Six Apple Thunderbolt Displays (27-inch), Apple LED Cinema Displays (27-inch), or third-party Mini DisplayPort displays.
- Three 4K displays: two connected via Mini DisplayPort and one connected via HDMI.
- One 4K Ultra HD TV or 4K display using HDMI and four Apple Thunderbolt Displays (27-inch), Apple LED Cinema Displays (27-inch), or third-party Mini DisplayPort displays.
- Two HDMI (HD or 4K) devices: one connected via HDMI and one connected via Mini DisplayPort with an HDMI adapter (see note below).
Note: Attach displays to different Thunderbolt busses when possible (see figure below). Do not attach more than two displays to any Bus. This means that if you use the HDMI port, be sure to then only use one of the bottom two Thunderbolt ports (Bus 0).
Which 4K displays can I use?
See Using 4K displays and Ultra HD TVs with Mac computers for a complete list.
Can I use more 4K Ultra HD TVs in addition to one connected to the HDMI port?
Yes. You can connect one additional 4K Ultra HD TV by using an adapter that conforms to the High Speed HDMI cable standard and connecting it to a Thunderbolt port. Check with the manufacturer of the cable to determine if it supports this standard. Do not use Thunderbolt Bus 0 to connect this additional device if you've connected a 4K Ultra HD TV to the HDMI port.

Use a single-link DVI adapter such as the Apple Mini DisplayPort to DVI adapter for DVI displays with a resolution up to 1920x1200. Use a Dual-Link DVI adapter such as the Apple Mini DisplayPort to Dual-Link DVI adapter for resolutions up to 2560x1600.
Mac Pro supports a total of two single-link DVI displays. If you connect a third DVI display using a passive adapter or a display via HDMI, it will cause one of the three displays to become inactive.
Can I connect more than 2 DVI or HDMI displays?
Mac Pro supports a total of two DVI or HDMI displays when connected via the built-in HDMI port or using the Apple Mini DisplayPort to DVI adapter. To connect additional DVI displays, use an active DVI adapter such as the Apple Mini DisplayPort to Dual-Link DVI adapter. You can connect up to six active adapter DVI displays. This requires a powered USB hub since Mac Pro offers four USB ports and you will need six to connect them all.
