external monitor mirroring

Hi- I have a mac book pro 2022 m2. I have two external monitors hdmi hooked up to a docking station. They are mirrored and I'd like to unmirror them but in the Display I cannot do that. Extended display does nothing. Is there a trick to this or is my mac unable to support two distinct monitors?

If it is a 13” M2 model, it supports one external display.


The 13” and 14” models are similar in size, but the 13” M2 MBPs have only two USB-C (Thunderbolt) ports, as opposed to the three on the 14” and 16” M2 {Pro/Max} MBPs.

What processor chip is in your MacBook Pro? Is it a 'base' M2 chip, a M2 Pro chip, or a M2 Max chip?


The 13" M2 MacBook Pro only supports one external monitor. There are workaround products to drive two or more displays in a second-class way, but there is no way to add more first-class hardware-accelerated video outputs.


I believe that 14"/16" MacBook Pros with the M2 Pro chip can support up to two external monitors, and that 14"/16" MacBook Pros with the M2 Max chip can support up to four external monitors. (Double-check specifications to be sure.)


If you have one of the machines with a M2 Pro chip or a M2 Max chip, is the dock a Thunderbolt dock, or just a plain USB-C one? Macs don't support DisplayPort MST daisy-chaining and will only drive two monitors off the same host port if (a) that port is a Thunderbolt port, and (b) the device connected directly to it is a Thunderbolt device such as a Thunderbolt dock. (There are a number of Thunderbolt docks that can drive two non-Thunderbolt monitors which have resolutions of 4K or less, if the Mac in question supports two or more external displays.)

It’s easy to get USB-C to HDMI adapters and adapter cables, but they won’t let you overcome the limit of one external display. Those adapters rely on support from the computer.


There aren’t Thunderbolt to HDMI adapters per se, unless you count Thunderbolt docks that have HDMI ports. DisplayPort Alt Mode is enough to support typical HDMI adapters. But even with Thunderbolt, the one external display limit of the 13” M2 MacBook Pro would be a limiting factor.

Thank you for this! Very helpful but I'm not so sure what some of this means.

It's an M2-I can't find where it says 'pro chip' or 'max chip' so I'm guessing that means it's a 'base' M2 chip?

Yes it's 13".

It's a thunderbolt connection to the Mac. right now it's going 2 ext monitors via HDMI to a docking station and to the computer via thunderbolt (from docking station to mac).

the monitors only have HDMI...would it be a thing to get HDMI-thunderbolt adaptors? I don't know it that exists or...? Thank you so much!
