New Mac Studio and Mac Pro Support Up to Eight 4K Displays, Mac Pro Works With These PCI Cards

In a pair of support documents, Apple has listed various external display combinations that can be used with the new Mac Studio and Mac Pro. For example, both Macs support up to eight 4K displays at 60Hz when configured with the M2 Ultra chip.

Apple Pro Display XDR Lifestyle
The new Mac Studio has an HDMI 2.1 port, and the new Mac Pro has two. These ports each support an 8K display at 60Hz, or a 4K display at 240Hz. Apple says the M2 Ultra chip also supports up to six Pro Display XDRs.

The previous Mac Studio supported up to five external displays when configured with the M1 Ultra chip, so the new model supporting up to eight is a considerable improvement. Apple silicon has come a long way in this area since the first Macs with the M1 chip were released in 2020 with native support for only a single external display.

Apple has also published support documents explaining how to install PCIe cards in the Mac Pro and listing compatible types of PCIe cards. Unlike the Intel-based Mac Pro, the new model does not support graphics cards due to Apple silicon's unified architecture.

The new Mac Studio and Mac Pro launched today after pre-orders began last week.

Can we all take a moment to appreciate how this is all being generated from a single chip, with integrated graphics and memory?

?

I get that people aren't happy with the Mac Pro's inability to add memory or external graphics but holy ? this is crazy.

I like how they threw in those 1990's speakers to balance out the look
Those are Genelecs (from Finland), great speakers: https://www.genelec.com/g-series

I find it interesting how they chose to convey a left-handed user's setup - with mouse and styli on the left.
They say left-handed people tend to make for better artists (it's a right hemisphere thing). I have to think that was intentional, in such a carefully curated shot.
I think you're overthinking it

Would love to hear stories and photos of people using 8 x 4k monitors in their setup. Like one photo.. from anyone, at all
Are you really that myopic that you fail to imagine a use case for this?

Real-world example: in the AV world, we use Mac Studios as media servers for large-scale events and exhibitions. We regularly drive 5+ 4K video processors from a single Mac Studio, and have developed our own proprietary solution to enable 8x 4K60 native outputs from a single Mac Studio M1 Max (no extra hardware other than Thunderbolt to DP/HDMI adapters required).

We could do with even more display output capacity, as the hardware ProRes decode engine in M1 Max/Ultra doesn’t even come close to capacity when playing back 16+ simultaneous ProRes 422 4K60 pieces of content.
