Satechi’s ExtendView USB4 Dual HDMI Multiport Adapter runs two extended 4K displays at 60Hz off one USB4 cable, and it skips the driver installs that make lesser hubs a recurring headache. One cable wakes the whole desk.
It’s $119.99 at Amazon and on Satechi’s own store, in a single Space Black finish.

Two extended screens with no drivers in the way
Both HDMI 2.0 ports carry 4K at 60Hz, and the adapter is plug-and-play across macOS, Windows and ChromeOS, so there’s no DisplayLink software sitting between the laptop and its screens.
Windows gets the full pair.
The catch runs the other way on older Apple silicon, since Macs with base M1 or M2 chips drive only one external display through it, and a base M3 MacBook needs its lid closed to run two. Windows 10 and 11 machines run both displays through a USB4 port, and iPads and iPhones stop at one external display.
Seven ports mapped across a five-inch bar
The port count splits into two HDMI outputs, two USB-C data ports and two USB-A data ports at 10Gbps each, plus a USB-C PD port that takes power in and passes it to the host. All four data ports run USB 3.2 Gen 2. Each port has one job.
The USB-C data ports carry no video, so monitors belong on HDMI and drives belong on the four data ports, with the labels printed on the housing keeping the split straight. The host cable feeds everything from the laptop’s USB4 port at a full 40Gbps upstream.
Power passes through and the cable tucks away
The PD port accepts up to 140W from a charger, the adapter keeps about 15W for its own operation, and up to 125W reaches the laptop while both screens and the data ports stay live.
The anodized aluminum body runs 5.55 inches long and 5.94 ounces, the host cable stretches 7.93 inches, and a built-in slot parks the USB-C connector when the adapter rides in a bag. It travels like a dongle. The dotted top panel matches the MacBook Pro it sits beside.

Buy it at $119.99 if your M3-or-newer Mac or USB4 Windows laptop needs two extended screens and no dock lives on your desk or in your bag. Skip it if the machine’s a base M1 or M2 Mac and the second screen is the reason you’re shopping instead of a bigger dock for a desk that never moves.
