Plugable Technologies USBC-768H4 USB graphics adapter 1920 x 1080 pixels Black

You’re just trying to add screens to your computer. It shouldn’t be complicated. Sure, adding one screen—no problem. Adding two screens? Still not that hard, but now you have to consider your graphics card and how many external monitors your computer will natively support. A MacBook with an M1 or M2 chip, for instance, only supports one. And adding four external monitors? Your options are a high-end docking station, or a handful of dongles and adapters coming out of every open port on your machine.

The USB-C or USB 3.0 to Quad HDMI Adapter (USBC-768H4) changes that. Now you can add four HDMI screens through a single USB-C or USB 3.0 port—all with a sharp 1920x1080@60Hz image, even on M1 and M2 Macs.

Big Results
Smaller than you might expect for a quad display adapter, this multiple monitor adapter still manages all of the heavy lifting involved with delivering your video signal across four monitors. But it’s how the adapter handles the task of parceling the pixels across your screens that’s interesting.

A lot of adapters rely on USB-C features not available on all systems. The USBC-768H4 uses a Silicon Motion chipset and a software driver to accomplish the task. From a user perspective, there isn’t much of a difference. Unless, of course, you happen to be on an M1 or M2 Mac. Those particular computers don’t support more than 1 Alt Mode display so the standard approach wouldn’t work.

It is worth noting, a driver download is required. On Windows machines, the update is automatic though we do recommend installing the driver manually. On a Mac, however, this is accomplished through the InstantView App. And remember, though they offer similar functionality, the DisplayLink driver won’t work with this adapter.

4 Here, 4 There
A USB to HDMI adapter for monitor expansion opens up new levels of productivity.

Dedicate an entire screen to spreadsheets, email, stocks, or anything else you’re working on.

The USBC-768H4 adapts to your style of multitasking. Use it to expand to one, two, or three screens. It works just as well if you aren’t tapping into all four ports.

Now, let’s talk about what this multi HDMI adapter doesn’t have. It doesn’t have an external power source. It also doesn’t have an unwieldy cord to manage. What it does have is a flat cable that tucks into the bottom of the unit when not in use.

When you’re ready to expand your screen count, flip out the connector and plug it into an open USB-C or USB 3.0 port. Now you just have to connect your four HDMI monitors. That’s it. The adapter will get any required power from the host. And when you’re ready to go, disconnect and toss the adapter in your bag.

Compatibility
The USBC-768H4 is designed to work well with a wide variety of computers.

With the option to connect to the host computer through USB-C or USB 3.0 (USB-C to USB adapter included), you’ll never be left looking for an adapter.

Speaking of adaptability, the Plugable USB-C or USB 3.0 to Quad HDMI Adapter works with Windows 10 and newer, and macOS 11+. And that includes Macs with M1 or M2 chips that would otherwise only support one external monitor.

Not compatible with ChromeOS.
