I just bought a brand new 2020 mac book pro and it doesnt do what my 2017 mac book pro did?

You did not buy the same model computer. You bought a new model with the M1 chip. This is like replacing your F150 with an 8 cylinder engine with a new model with a 4 cylinder engine and being upset that it does not have the same towing capacity as your old truck.

With respect to you being an unhappy customer, I am sorry about that, but we are not Apple employees here. We are users like you. Provide feedback to Apple if you want to tell them their new model computer does not live up to your expectations.

The specs cleary state that an M1 Chip Macbook Pro only supports one external display.

Return it and get a model that supports multiple external displays.

The 13-in MacBook Pro with Apple-Silicon M1 chip supports a huge External display, up to the 6K resolution of the Apple display HDR. It is Much more capable that the models that preceded it.

But it is possible that it does not match the way you used to work, (i.e, with multiple, smaller displays).

If and only if you purchased DIRECT from Apple you have 14-days to return or exchange the one you received for full value.

If you purchased for a Reseller, the Reseller's policies apply.

Why? You need a computer that can have multiple external displays. Several models can do that. The only way to know which models is to read their respective specs. I pointed you to their specs. How is that not helpful?

Here you go. You can compare the specs for all mac models.

Sorry I was not helpful. I am in the market for a new pickup truck. I don't think I'll buy a new model without ensuring it does what I need it to do. I need it to tow 12,000lbs. I'm sure not all new pickup trucks can do that so I'll check the specs of each truck before I make the purchase to confirm that it meets my requirements.

Because a computer is newer does not necessarily mean it does everything an older model did.
