Apple's newly announced high-end chip for the new MacBook Pro, the M1 Max, can support up to three Pro Display XDRs and a fourth 4K TV display all at the same time, a significant jump in support compared to the single display support that the M1 chip provided.

The M1 Pro chip supports up to two Pro Display XDRs alone, while the higher-end M1 Max chip extends support to an additional Pro Display XDR and a 4K TV. To support this, the new 14-inch and 16-inch MacBook Pros feature three Thunderbolt 4 ports and an HDMI port.

Overall, the new MacBook Pro with the M1 Pro chip supports up to two external displays with up to 6K resolution at 60Hz, while the new MacBook Pro with the M1 Max chip supports up to three external displays with up to 6K resolution and one external display with up to 4K resolution at 60Hz, according to Apple's tech specs.

Apple announced completely redesigned 14-inch and 16-inch MacBook Pros models today during its "Unleashed" event. Be sure to catch up on all of the announcements right here on MacRumors.com.

Really looking forward to the benchmarks for the M1 Pro and M1 Max. It seems like both of these chips are more powerful than expected graphics wise. Even the 16 core is more powerful than a maxed out 2019 16” so the 24 or 32 core has to be outrageous!

No mention of if Thunderbolt can support 8K, which would be useful as they mentioned editing 8K footage.

And no mention of the HDMI format. But the specs say 4K max, so probably 2.0a, not 2.1.

8K monitors (and TVs) are likely to get much more common and affordable in the life cycle of these Macs, so it would be nice to support them. They will be great for retina pixel density on a larger screen.

I guess they had to leave something on the table for next year. I am surprised that the HDMI can't handle 8K out, for just that reason of the video editors they're promoting this for.

Assume eGPU is still NOT supported by M1/M1 Max/M1 Pro models? Do not see those disclaimers mentioned yet. Not sure it is necessary, but is/was a concern for some.

I believe the blockage is mostly lack of drivers, and no, I wouldn't expect that to be remedied right now. :(

Impressive machine and amazing how many pixels they can push, yet no serious gaming?

Apple will never make an external graphics card and it looks like eGPUs are neither something they want to support.

a significant jump in support compared to the single display support that the M1 chip provided.

This would be more accurate if worded ‘provides’ instead of ‘provided’.
The M1 is still a current chip in latest gen. shipping products, so shouldn’t be referred to in past tense.
