Questions about this item

What does the Thunderbolt 3 interface cap at for external display bandwidth?

Each Thunderbolt 3 port supports DisplayPort video output so you can drive one 4K or 5K monitor per port at full resolution.

What physical space does the all-in-one chassis need on a desk?

The 21.5-inch Retina 4K display sits in an aluminium enclosure that tapers to 5 mm at the edges, so only the footprint of the stand is required.

How is the memory upgraded and what step is often missed?

The 8 GB of 2400 MHz DDR4 is socketed but access requires removing the display panel; many people forget to re-seat the thermal sensor cable when reassembling.
