ACCELL USB-C to 3 HDMI Multi-Monitor Hub Review

If you’ve got a new Surface Book 2, HP Elitebook x360 G2, or ZBook and would like to expand your desktop working space to three screens without sacrificing the quality and vibrance the device would perform at on a single display, then this accessory is what you’ve been searching for. Although there are many ways to use this accessory, that is one of its crowning achievements.

With the world’s newest laptops, hybrid notebooks, and workbooks on the market capable of high-end visual output supported through USB-C, ACCELL is one of the companies producing excellent quality products that help users take full advantage of their hardware. This hub can even be used as a 4K HDMI-splitter as well, among other creative alternative features offered.

Join us for a discussion on the usefulness of the U228B model ACCELL USB-C to 3 HDMI Multi-monitor Hub as well as a semi-breakdown of its impressive specs and what some of it means.

Today we will be talking about the ability to output 4K resolution graphics to multiple HDMI or DisplayPort monitors through the USB-C port of these high-end computers without losing the quality and functionality provided by the original source device itself. ACCELL is offering a variety of accessories on their official website as well as Amazon, but we’ll focus on a brand new family of models geared to the latest standards, functionality, and best quality.

There are three variants of this model series; the U227B which supports two HDMI outputs from a USB-C source, the U226B which supports three DisplayPort outputs from a USB-C source, and the U228B which supports three HDMI outputs from a USB-C source. All three models are equipped with ThunderBolt 3 compatibility and MST.


There’s a lot you can do with this unit. Although official support only exists for Windows 10 on the unit we received, there’s still an incredibly crisp display coming out when we plug in high-end smartphones through USB-C to an HDMI monitor or television. For example, the Sony Xperia XZ2, Samsung Galaxy S8+, and Galaxy S9 all benefited from the high-end visual capacity of the ACCELL U228B without any hint of latency or drop in fidelity. This could be incredibly useful for gaming even if its main usage is productivity.

The crux of the matter here is that whether you’re seeking productivity across multiple screens with one of the latest high-end workbooks (like Microsoft’s Surface Book 2) or just need a 4K / 1080P display adapter with multiple outputs and no latency for gaming on Windows 10, this unit does the job without compromise. Some of the lesser known features of this unit include Advanced WideEye tech for long range data transmission and even support for Stereoscopic 3D.

One screen can be used for each application or video wall configurations can even be put together if two units are used together (allowing pairing of up to 6 displays from one USB-C video source device output). DVI and VGA monitors can even be hoked up to the adapter if active HDMI adapters are used as well, further increasing the diversity of the device.


When people spend the money to invest in top tier productivity technology or PC Gaming tech they often seek a cheap solution for things like extra wires or adapters they didn’t realize they needed. The result is a frustrating experience with low quality images and often latency issues. Instead of going for the cheap solution, I suggest taking a strong look at ACCELL accessories which are far superior to the cheap alternative.

Capable of the highest standards in data transmission and with a quality hardware finish and firmware chip, the ACCELL USB-C to 3 HDMI Multi-Monitor Adapter (MST Hub) (U228B Model) has been created to be the visual adapter of our dreams. Staying far away from any shortcuts in production, this device should be a lesson to tech users. This is the kind of high quality experience that can happen when you select the adapter appropriate for your already powerful electronics. With a polished product such as this, and so much diversity of functionality, money can buy you happiness.
