If you’re looking to run two 4K displays side by side, Elgato’s new Thunderbolt 3 Dock may be the solution for you. The $299 dock comes with two USB-C ports, two USB 3.0 ports, a DisplayPort, and an Ethernet port for the Wi-Fi adverse.
You can charge your laptop over USB-C and run two 4K monitors at 60Hz using the extra USB-C port and the DisplayPort, and keep your devices fully charged (unless you have a newer smartphone with USB-C, then you’ll need an adapter). At $300 it’s definitely pricey, but the Elgato Thunderbolt 3 Dock may be worth it if you need the screen real estate. The dock will be available on June 6th on Amazon.
