Test 4 Port types

Connection options and limitations.

This isn’t so much a performance test, but it is a very important part of how a particular display will satisfy your specific needs. First of all, if your Mac is equipped with USB–C then the Dell and Samsung displays stand out from the rest of the field as the only ones featuring this input option; the others will require adaptors. However, if this isn’t a concern for you, then the AOC, Dell and Samsung units all offer a good selection of ports: DisplayPort in and out, HDMI, and in AOC’s case DVI as well. These also have USB passthrough and power, from a USB–B port in AOC’s case and USB–C in the Dell and Samsung.

The Acer and Philips displays have no USB ports, so they don’t act as port hubs for data or device charging. Like the

AOC these offer an old–fashioned VGA port for analogue video connections, but their modern HDMI port (and in Acer’s case DVI as well) should be used in preference.
