Mac Mini M4 / M4 Pro with two 4k@120hz displays

Hi there!


I saw the specification for the new Mac Mini, but still wondering if I can run two 4k displays at 120hz with (ideally) the M4 version, or at least with M4 Pro. I can do that with my MBP M1 Pro, so guess M4 won't be a downgrade on this front, but just want to see if I can run with base M4 version.

Mac mini (M4, 2024) - Technical Specifications - Apple

M4:
Simultaneously supports up to three external displays:
* Up to three displays: Two displays with up to 6K resolution at 60Hz over Thunderbolt and one display with up to 5K resolution at 60Hz over Thunderbolt or 4K resolution at 60Hz over HDMI
* Up to two displays: One display with up to 5K resolution at 60Hz over Thunderbolt and one display with up to 8K resolution at 60Hz or 4K resolution at 240Hz over Thunderbolt or HDMI

M4 Pro:
Simultaneously supports up to three external displays:
* Up to three displays: Three displays with up to 6K resolution at 60Hz over Thunderbolt or HDMI
* Up to two displays: One display with up to 6K resolution at 60Hz over Thunderbolt and one display with up to 8K resolution at 60Hz or 4K resolution at 240Hz over Thunderbolt or HDMI


MacBook Pro (14-inch, 2021) - Technical Specifications - Apple Support

M1 Pro:
Simultaneously supports up to two external displays:
* Up to two displays: Two displays with up to 6K resolution at 60Hz


6K @ 60 Hz HDR ≈ 51.30 Gbps

4K @ 120 Hz HDR ≈ 41.80 Gbps (81%)

So that should be possible for video bandwidth.
