How many displays can be connected to Mac Studio (2025) with M3 Ultra

Mac Studio (2025) models with the M3 Ultra chip have two port groups that together support up to eight external displays simultaneously, based on the resolution and refresh rate of each external display.

Mac Studio (2025) with M3 Ultra

Identify your Mac Studio model and identify its ports.

You can connect displays to the Thunderbolt 5 ports and HDMI port on the front and back of the computer.

Using a supported hub or daisy-chaining displays can enable up to two displays over a single Thunderbolt port, but does not increase the maximum number of displays you can connect. Connect the display with the highest resolution first.

Mac Studio (2025) with M3 Ultra has two port groups that each support up to four displays. An 8K (7680 x 4320) at 60 Hz or 4K (3840 x 2160) at 240 Hz display connected over HDMI uses the resources of two displays in that port group.

  • Port group 1: the two Thunderbolt ports on the front and the HDMI port on the back

  • Port group 2: the four Thunderbolt ports on the back
