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 ResultsSmaller 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 ThereA 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.CompatibilityThe 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.

Leveraging 40Gbps of bandwidth made possible by Intel's Thunderbolt 3 technology, Plugable's Thunderbolt 3 Dual DisplayPort Display Adapter (TBT3-DP2X) enables content creators and power users to connect two additional displays to their Thunderbolt 3 enabled laptop with uncompromising graphics performance. The adapter housing is made from sleek, lightweight aluminum allowing for easy expansion of your Thunderbolt 3 laptop or tablet on-the-go. Not all Thunderbolt 3 systems are compatible with dual display graphics adapters. See important details regarding system compatibility in the section below.Dual Video Outputs From a Single Thunderbolt 3 Display AdapterThunderbolt 3-attached displays tap directly into the power of your system's graphics processor to enable high-performance, low-latency output without utilizing additional system resources.Supports two DisplayPort displays up to 4096x2160 @ 60Hz (4K/UHD). Backward compatible with 1920x1080 (1080p) displays as well. Thunderbolt 3 is a powerful technology, and system manufacturers have substantial discretion in how they implement various Thunderbolt 3 technical elements and features. As a result, compatibility information is complex and some currently available Thunderbolt 3 systems aren't compatible with our dual graphics adapters. To work as expected with our Dual DisplayPort Adapter, the host Thunderbolt 3-enabled system must meet the following requirements:- The system manufacturer must have physically routed two DisplayPort video output lanes to a single Thunderbolt 3 port. Thunderbolt 3 systems from Dell meet this requirement, the specifications for Thunderbolt 3 systems from other manufacturers may vary- Current Thunderbolt 3 host firmware ("NVM") from the system manufacturer must be applied to the system- Requires updated system UEFI BIOS, Thunderbolt 3 drivers, and graphics processing unit (GPU) drivers from system manufacturer- Please note this adapter connects to monitors using the DisplayPort standard, which is different from HDMI. A separate HDMI version of the adapter is available if connectivity to HDMI displays is neededPlease refer to the attached Specification Sheet for additional compatibility information.Host System RequirementsWindows 10, 8.1, and 7 systems with Thunderbolt 3 support built-in. Adapter will not function if attached to a non-Thunderbolt 3 capable USB-C port. Thunderbolt 3 port required for operation.Usage With Non-DisplayPort Displays (HDMI/DVI/VGA)Adapter video outputs are pure DisplayPort, not Dual-mode (DP++)and are incompatible with ‘passive’ DisplayPort to HDMI/DVI/VGA adapters. You must use ‘active’ adapters if protocol conversion is required. If HDMI connectivity is required, please use our TBT3-HDMI2X-83 adapter.
