InnoView Laptop Screen Extender 15.6" Dual Monitors Stacked Folding Triple Monitor (Wins/Mac) 1080P Triple Portable Monitor for Laptop 90°/180° Automatic Rotation Black

First off, the Innoview can work without connecting the external power-supply. IF your laptop USB-C port can provide enough current to power both screens -- but its less stress on your laptop USB-C pulling all that current if you use the external power-supply, and the dual-screens are brighter doing it too. Also, I had some initial issues getting laptop to to recognize Innoview & let Innoview autorun its driver-installer, so I recommend first thing, plugging Innoviews power supply in its top USB-C connector & letting the Innoview fully boot up with "Innoview" splash screen, before connecting Innoview to your laptops USB-C. Another thing you'll notice from the pic is I have all 3 connectors used, I was unable to get both screens running from the same USB-C port as the documentation showed, I needed a USB-C pory for bottom screen & HDMI port for the top. The other thing you will notice is that even though my multiport USB-HDMI hub has USB-A, usb-c & HDMI ports, I was unable to run both displays through it no matter what combination of ports I tried. Perhaps if I used a full external-powered docking-station I could run both monitors from the docking station, but this hub at least would not run both. What this means is if you are running out of USB ports, a hub like mine would be good to let you run 1 display + give you extra USB ports for things that aren't displays. But even though this hub had USB ports & an HDMI port I could not run both screens through the hub.

The Good: The hardware seems to be high quality. The screens are sharp and bright, and the unit feels solid and durable. The Bad: The drivers were a huge pain to install. Just when I thought it was working correctly, it stops. Here's what happens: - Both screens come on. You can even move apps or browser windows onto them. - As soon as you try to *do* anything on screen 2 (top) like play a video or scroll the browser window, the driver crashes and it enters an endless loop of crashing and restarting. Both monitors cycle off and on throughout this process. All you can do is unplug it or disable the monitor in Windows display settings. - If you disable just screen 2, screen 1 works normally. But why would I buy this product for only half of it to work? Also, it only works this much with the USB-C cable connection. It's also supposed to work with HDMI+USB, but Windows never even recognizes screen 2 with this cable configuration. There's a USB cable with wall power adapter in the box, but nothing in the instructions tells you when or why to use it. The documentation clearly claims "single-cable connection". If they update the drivers to fix this critical problem, I'll also update my review. I would give it 1 star, but the hardware really does seem to be quite good. I just wish it worked! Update (May 2025) - New ThinkPad laptop and now it doesn't work at all. I'm taking off another star. Don't waste your money.

I recently got my hands on this dual-screen portable monitor stand, and let me tell you, it's been a game-changer for my workflow. Right off the bat, the color accuracy and vibrancy of these screens caught my eye. I'm talking crisp, vivid displays that make everything from spreadsheets to videos pop. Now, you might be thinking, "Two extra screens must take up a ton of space, right?" Wrong. This design is sleek and surprisingly space-efficient. The screens sit one above the other, not side-by-side, so it barely takes up more desk space than my laptop alone. But the real magic? It's like having two additional monitors without the clutter. The boost in productivity can't be overstated. Having the extra screens lets me spread out my work, keep reference material handy, and multitask like a pro. It feels like I've got a command center at my fingertips. Setup was a breeze, too. It's literally plug-and-play. My laptop powers the screens directly, so no need for extra power cables cluttering up my workspace. A single Type-C cable is all it takes to get everything up and running. No fuss, no muss. Overall, this portable monitor stand has been a stellar addition to my setup. It's efficient, user-friendly, and has significantly improved my work efficiency. Highly recommended for anyone looking to up their productivity game without sacrificing space.

Great portable monitor for travel. Works well and doesn't take up a lot of room. It's weighs about the same as my laptop so not a huge uplift in additional weight. Recently I have had issues that looks like others have had with the top screen not activating once I plug my work laptop in ( I didn't have this issue with my personal laptop). I rebooted it and it came back up but I don't want to have to reboot my laptop every day to get it to work. If I had of written this before that happened, I would have given it 5 stars. But otherwise this is a good solution for someone who travels and needs more than their laptop screen or doesn't sit at a traditional desk

I bought this monitor primarily to use as a digital "map" for when I'm playing dungeons and dragons and other TTRPGs. It lays flat and keeps a low profile to the table, the colors are excellent, and with a pair of screen protectors installed on the screens, I and my players can place minis directly on the maps. I've also used this as a temporary monitor for a laptop that broke and it worked great for that as well. I'd love the color to be a little bit brighter, but it's a cost-effective solution (especially if there's a coupon, which seems to happen frequently with this device) and it works exactly as described! Installation of the on-board drivers was easy and quick, and I was ready to go within just a few minutes. Overall, I would definitely buy this again! it's light and thin enough to fit into a standard 15.6" laptop sleeve, folds out to 24 inches, and works great. I'm very happy with this purchase.

LOVE having two additional monitors to work with! LOVE that this is easily transportable! LOVE that it's easy to connect to my laptop. HATE, HATE, HATE that every time that I use it - I will be working on multiple items at a time and "POOOFFF!!!" black screens - everything GONE! Yup, computer is wiped out and reboots. It's happened during Zoom meetings, happened with important spreadsheets open - one that was unrecoverable - their add on Amazon clearly states 24/7 support (lie), they don't. I just called on a Friday night - and they said that their hours are Monday thru Friday (China hours). Went to the website, chat it closed and the contact us message reads "Hello, dear If you have any user questions, please feel free to contact us. We will get back to you within 24 hours." So, alas, they do NOT offer 24/7 support. I will be returning my dual monitor and finding a reputable manufacturer that doesn't lie about their service and their product doesn't wipe out my workspace multiple times a day. This would be an amazing product - if it worked! UPDATE: Their support team HAS been in contact with me and is in the process of resolving the situation. So far, I am satisfied with their response and solution to the problem. I may have just been unlucky and received a bad monitor - other reviews are very positive and I have not seen other reviews that have experienced this problem. The many favorable reviews are why I purchased this brand/model. And I will say that I am STILL very impressed by the quality of this monitor, seems very well built. I'll update this review when the new replacement monitor is received and I have had ample time to use it and ensure that I don't experience the same issue.

Positives: pretty good screen quality, and excellent build for traveling. The case is strong that I do not need a monitor bag. Issues: I had to return another dual screen portable monitor because it did not work with Mac, but worked with Win without drivers. While this monitor works with both Win and Mac, it does not work well. A USB drive shows up asking to install drivers, and even after installation, you constantly had to close the popup window, both in Win and Mac, that USB drive is connected and disconnected. While the dual screen works, the software/driver is poorly written. I had to re-arrange monitor position after either reboot or sleep, both in Win and Mac.

I bought this portable dual monitor setup so I could use coworking spaces more efficiently. As a computer programmer, it is extremely useful to have your code on one screen, while the program you are building/debugging is on another. Unfortunately, this product does not do what it advertises. The page here says you should be able to connect a single USB-C cable and make it work. This is just false. I tried all 3 USB-C ports on my machine (including a USB-C/DP alt) and at no time did the upper screen turn on -- though it did "blink" from being "actually off" to "it's technically on but just showing a black screen" (like when you're booting up a computer.) Using both USB-C ports on the monitor didn't help either. The instructions are also unhelpful. It suggests going to Nvidia Control Panel, opening 3D Settings, going to the "Program Settings" tab, finding the "Win USB Display" (or "Macrosilicon USB Display," they use both titles in their instructions), and setting it to use integrated graphics. (Apparently, it doesn't play nice with Nvidia.) Except, there is *no* such program to add. This is after installing the driver and restarting my computer -- twice. There is a possibility that, since my machine is a Dell, it's just Dell's low quality manufacturing causing an issue, but either way, I'm not going to spend all day trying to get it to work with my machine. Either it does, or it doesn't. I will be sending this back for a full refund.
