Big question, how many monitors will it support with a docking station and on the computer its self? I had an on line conversation with a Appletech rep who answered 2 with external connectons. I didn’t feel like going through the sales pitches to get another question answered. I would like three monitors. I wonder if there are two hook ups to the docking staton and another to the lap top? I believe you told me you had three and the CPU can support five?

The MacBook Pro 13" M2 only supports one external monitor…

The MacBook Pro 14” M1 (M2 not yet available in the 14”) supports 2 additional displays at 6K or 4 displays if you get the M1 Max chip. The four displays would be 3 running at 6k and one running at 4K.

Any docking station is not going to add more monitor capability. That is driven by the graphics portion of the M chip. There are external graphics card adapters one can purchase but I avoid those.
