In fact, what this element supports was not specified. I first bought two for a MacBook Air and although both worked, only one was recognized and the other used mirroring by default. Even the start of just one was far behind. I am using Mac OS 2011 High Sierra.

It looks and works like a second screen and the picture quality is pretty good too. One problem I had is that it's very difficult to get the screen out. I hope mine is just bad but I have to remove the screen from my laptop, pull it out of the case and then put it back on when I want to use it.

The product worked for the first month and then stopped working. There is no way to contact the manufacturer. Terrible experience.

I don't know how they did it; but they managed to allow the usbc port to receive video signals, which (as far as i know) is not possible with a simple adapter. For all other options, you either used a USB port or a mix of USB and HDMI ports. I would recommend this product to anyone who wants to reserve their USB ports for something else.

Definitely overpriced. But I love how you can attach it to your laptop with magnets and pull out anything in your laptop bag. Very comfortable but seems easy to break. overpriced.

Very happy with my second screen. Excellent quality HD picture. So easy to install. Good for on the go. Now I can't imagine how I could work on my laptop without a second screen. Simple instant connection, use. Delivered on time and in good condition. I actually bought two and have recommended this product to several of my colleagues.

When I first ordered it was delivered with no problems. It was packaged in the regular Revain packaging which resulted in damage in transit. In any case! I have reordered and am absolutely thrilled! The connection process was easy. I have a Macbook Pro 12 inch. Before setting up, I installed a link to the display on displaylink.com. The "Wait" message disappeared after 2 minutes and everything went fine.

I like the monitor very much. However, after 3 months the glue holding the magnets came loose. I lost a magnet and how the screen won't stay in place.

The Trio monitor is a great addition to my work computer. This allows me to open multiple applications and improve my productivity.

Works as it should. The other side of the secondary screen can be a bit heavy and difficult to install. I usually prop it up with something small underneath.

It only comes with 1 display, although it mentions "Trio Portable Monitor for Laptop, Mobile12.5 Dual & Triple Screen". Don't be an idiot :) .

I still think the concept is great but I would wait for version 5.0 as there is so much to do. The box arrived crooked, there were traces of glue on the screen and on the laptop there are the same stickers that keep falling off. And pulling this umbrella out of the house is not that easy, as you can see in the video. Did I mention how hard it is? In other words, if you need to quickly call Google Meet and want two screens to share things - just to get things going, it's not worth it.

I use it as a second monitor on my laptop at work. The extra space is good. You can install it so that it slides out to the left. Very happy with the performance I get from it.

I need an extra monitor for my laptop and the trio did the job. I like the idea and the delivered product. However, I just couldn't fix my screen with magnets. it seems to be slowly sliding down because it is too heavy.

Delivery was earlier than expected which was a big plus. The installation instructions were very simple and clear. So far this seems to be a very good product for the money. At the moment there are no complaints.

Customer service is terrible. AD says it works with Chromebook. It is not. It's only after you've bought drivers for Chrome OS and tried to download them that you'll find that there are no drivers for Chromebook. When I contacted customer service it took 3 days to answer the question which monitor I bought. I replied that I had never heard from them again. If you have a non-USB Chromebook, don't buy it

Update February 2022: Please note that sidebar brightness can be adjusted by touching the very edge of the sidebar bezel. Like most, I haven't read the instructions, but stumbled across it by accident. I tried another company's side monitor and it didn't work and felt flimsy, but this one is sturdy and stays firmly on my laptop screen. Feels much more durable. Very satisfied and highly recommended!

Very convenient, everyone in the office loves it! This device is too big for my laptop but I think I have a very small laptop. That's why I bought a stent. It works fine on my work laptop.
