With that, you'll need a USB-C (Thunderbolt 3) to DisplayPort 1.4 cable to enjoy 4K resolution at 120Hz from your MacBook. You can buy a 4K monitor with a DisplayPort 1.4 port and 144Hz refresh rate. However, there's another way to make the best of your MacBook's Thunderbolt port if you are tight on your budget and still want 4K goodness. These monitors are quite pricy, and you can always get a USB-C monitor and pick one that offers USB-C output for daisy-chaining. So you can pick the Thunderbolt 3 end-to-end chain by investing in a solid quality cable as well as a Thunderbolt 3 monitor like LG 27MD5KB-B or Samsung 34-inch CJ791. Things are not the same on the other side of the bridge. Which One to Pick: Thunderbolt 3 or USB-Cįrom the above comparison, it's quite clear that Thunderbolt 3 offers more data transfer speeds, up to two 4K displays, and better daisy-chaining support for the macOS running MacBooks, Mac Mini, iMacs, and Mac Pros out there.
