Correct, but why would you use 3 screens when you can use just 2? And anyway I use external keyboard with numeric keys and a magic mouse instead of the trackpad. So why should I keep my Mac open anyway?

If you can use two 5k displays at the same time, you can probably use just one...

Only if you buy specific Thunderbolt-supporting 5k displays. You can't get one off the shelf and have it "just work(tm)".

They did.

According to the spec:

One 4K display (4096 x 2160) 30-bit @ 120 Hz

One 5K display (5120 x 2880) 30-bit @ 60 Hz

Two 4K displays each (4096 x 2160) 30-bit @ 60 Hz

You can't use the touch bar with the lid closed.

My guess is those are Thunderbolt-connected displays
