18.5" 100Hz Dual Portable Monitor Built-in Speakers 115% sRGB 315°Adjustable Dual Stacked Folding Monitor (Wins/Mac) 1080P Laptop Screen Extender for Laptop(No Driver Needed)

Wow, what a nice dual-screen (dual-panel) monitor!! It has two 4K high-quality screens separated by about an inch of bezels. You can place the entire monitor "vertically" with the two screens in landscape orientation and stacked top and bottom for a total resolution of 3840w by 4320h, see my photo below and the product photos; or "horizontally" with them in portrait orientation side-by-side for a max resolution of 4320w by 3840h. In my photo this dual 4K monitor is on the left; the right unit is an older InnoView dual 18.5" 1080p monitor, same brand. At the native (dual) 4K resolution the text will likely be tiny, so I set my Mac to display at 2560 by 2880 in what InnoView calls "splice" mode, i.e., the two panels are detected as one single display by my Mac. The two other modes are mirror (the two panels display the exact same screen from your computer) and extended, whereby the two panels show independent screens. There's a legal paper sheet with instructions that try to explain all these, but I can't say they're well written or easily comprehensible by the average user! Luckily, at least if you work with Macs, the setup is pretty simple. Just remember the top button on the right side when in landscape orientation, is used to turn the "splice mode" (confusingly, called fill mode on the monitor itself) on or off. In my photo, splice mode is on, so the two panels are treated as a single display screen by my Mac. One deficiency with the 23.8" InnoView model is it only goes up to 60Hz in refresh rate, whereas my older dual 18.5" model can go up to 100Hz which is what I use. One more minor thing is this "portable" monitor does not have a battery inside so you'll need to power it from the included adapter or from a powered C port on your computer. Overall, this is an excellent display for those needing tons of real estate space on their computer display! I don't play games so the 60Hz refresh rate is fine by me, and I'm quite happy with the screen quality, brightness, and size. It can be driven through a C port, HDMI, or DP.

I’ve been using the InnoView INVPM407 (IPS) 16” 2.5K 120Hz (2560×1600, 16:10) with both a MacBook Pro 16” M1 Max and a Mac mini M4, and my experience has been excellent. The shipping experience was excellent as well. The monitor arrived well packaged, properly sealed, and in completely brand-new condition. Everything inside the box was neatly organized, and the monitor arrived in perfect shape with no dead or stuck pixels, which was one of my biggest concerns when purchasing a portable display. One thing that is worth mentioning—and this is a macOS issue rather than a monitor issue—is that macOS initially detected the display as a 16:9 monitor instead of its native 16:10 aspect ratio. Because of that, enabling HiDPI resolutions resulted in black bars at the top and bottom of the screen, preventing the entire display from being used. The solution was BetterDisplay (Free version, macOS only). It allows macOS to recognize the monitor using its native 2560×1600 (16:10) aspect ratio, after which HiDPI works correctly across the full screen with no black bars. Once configured, everything worked perfectly. I was also able to enable the full 120 Hz refresh rate, making the monitor perform exactly as expected. It only takes a few minutes to configure, and after that the experience is excellent. The 2560×1600 resolution provides much more vertical workspace than a standard 16:9 monitor, making it ideal for software development, reading documentation, multitasking, and productivity. I also spent a little time calibrating the display. The best results came from using a small amount of Night Shift and increasing the display’s color temperature to around 6700 K using macOS’s built-in Display Calibrator, which provides much finer control than adjusting the monitor’s on-screen menu. I keep the monitor’s hardware brightness at 100%, and the final image looks warm, natural, and very comfortable for long working sessions. The built-in kickstand on the back of the monitor is also surprisingly sturdy and stable. It holds the display securely, is easy to adjust, and works very well for portable use. For desktop work, I also mounted it on a VESA monitor arm, which works exceptionally well. It transforms the monitor into a very ergonomic second display, keeps the desk clean, and makes it easy to position at eye level for long coding sessions. Compared with the outstanding Retina display on my MacBook Pro 16” M1 Max, I’d estimate this monitor delivers around 75–80% of that visual experience, which is impressive considering its price. The colors are vibrant, contrast is very good, and the 400 nits of brightness are more than enough for indoor use. Another major advantage is the single USB-C cable connection with the MacBook Pro for both video and power, while it also works flawlessly with the Mac mini M4. Overall, this monitor exceeded my expectations. If you’re a Mac user, especially a developer or anyone looking for a portable second display with a 16:10 aspect ratio, 120 Hz, HiDPI support, and excellent text clarity, this is an outstanding value for the money. If you use macOS, I highly recommend spending a few minutes configuring BetterDisplay so the operating system recognizes the monitor’s native 2560×1600 (16:10) resolution correctly. The improvement in image quality and usability is absolutely worth it. I would definitely buy it again. I’ll continue updating this review over time if anything changes or if I discover anything worth mentioning during long-term use.

Once I got it working, this thing was great. It's kind of amazing how much it adds to a laptop setup for such a reasonable price. My only issue was the initial connection. It wouldn't work until a brief discussion with InnoView's very helpful AI bot helped me realize you need to use the included USB-C cable, which carries both power and data. After that, it was completely plug-and-play with my MacBook Air M2 running Sequoia. It gives you a huge amount of screen space, is incredibly light, and the all aluminum construction feels sturdy. The display isn't quite Mac Retina quality, but it's excellent for web browsing, documents, spreadsheets, and general productivity. Designers may want something higher-end. It folds up easily, fits in a backpack, and is surprisingly power-efficient. My MacBook Air can run all three screens for 4–6 hours on battery alone, and when plugged in, the monitor pass-through charges the laptop. Overall, a great addition to a portable workspace-road warrior-FDE lifestyle.

Ok, just to start what is the use case for this product? For me this is a touchdown office monitor setup. When traveling I was taking a bunch of laptops, portable monitors, etc and this helps me streamline and be more productive. For me I will arrive at a location and spend about a week working in a fixed location and this monitors setup shines here. I can cut the number of devices down and have a much larger set of screens to work with and see my cad, code, and other dense applications so much better than the small 14", 17" portable screens that I had been using. The trade off is weight, this is a checked bag item full stop. It is very heavy and large so getting this into a carry on would be a nightmare. That said it is sturdy and in my hard case I have no reservations about checking it for flights. Using this in conjunction with a powerful mini-pc I was able to cutdown on my carry on weight drastically. As each laptop I was using had to go into the carry on as they had lithium batteries but now my heavy powerful items are all checked baggage and I just move with a thin and light for the trip and pull this out for the real work. So all that said what are the downsides? The first is weight, this much monitor is heavy no getting around that. The second is image quality, I was disappointed with the image and would not recommend this for anything needing color accuracy. The third is brightness, This monitor setup struggles with light output. Even at 100% it is less output than I regular laptop and drastically lower than a true monitor. I have included some images of a Lux meter that I have and from this you can see that in a non HDR setting the dual screens hit 150lux while in HDR they hit 330lux. This compares to a desktop monitor at 760lux in non HDR. Now note that lux does not equal lumens but is a different light measurement entirely but the important part here is the scale. This lack of output is part of the color issue as you will be cranking the settings trying to get light causing the colors to drift even farther from source. For usability this earns full marks. You can connect this with usb-c or displayport and be up in moments (I did not test HDMI). The OSD is a bit fiddly but after a bit I got it working well. The three buttons are used for navigating the OSD and other than the back button also switching the mode from dual screen to single if you press back to many times in a row it works well. The stand feels questionable but I was proven quite wrong on this as it was quite stable and had very little wobble when opened. The speakers are a joke, I would just assume that you don't have them. The speaker quality is terrible and the sound output is less than a laptop. Overall this is an amazing product that filled a need I had. As this is in a class of its own it is hard to level the critiques I have to harshly but I would say that if they made a V2 with better light output I would pick it up instantly. So if you need a "luggable" for extended work this is a hard product to beat.

Excellent dual monitor for the money! It has two USB C ports, one of which is for power supply (included in package), the other for connecting to your computer. Doesn’t matter which port is for which, but you must supply power. So this means a single C port is used for video connection which further means the two panels are treated as a single monitor by default. This last point has ramifications for Mac users (I’m not sure about the other operating systems). My attached photo shows this InnoView dual monitor (each panel 18.5 inches) connected to my MacBook Pro M3 Max in docking mode, together with a LuckyFive 24-inch WQHD monitor. Out of box when connected to a compatible Mac, the InnoView is in “splicing mode,” which means the two panels are used as a single vertical monitor. You can also, of course, use InnoView in mirror mode, where both panels duplicate the main screen, great for one-on-one sales pitches. To use the two panels as separate monitors, on the Mac you’ll need to install a driver that’s supplied from the monitor itself. The instructions are clearly given, although the steps are a little involved if you’re not used to installing drivers on a Mac. Not too bad if you want this “extend mode” (meaning two separate monitors). I didn’t do this. Instead I simply stay in splicing mode but rely on Mac’s windows arranging functions to place windows on the InnoView as I like. Macs remember windows’ positions as long as you don’t update the system and restart, so it’s pretty straightforward. The InnoView panels are each 1080p in resolution, with refresh rates of 60, 75 and 100. The frame is well made and the stand can stop at different angles and support the monitor securely. Image quality is very good for a 1080p monitor. And in splicing mode, the total resolution is 1920x2160. If you trade or code for a living and your desktop space is limited, I highly recommend this InnoView dual monitor. Just make sure your computer supports external displays, especially if you want to use InnoView in extend mode where the two panels display contents independently.

I purchased this to have an additional monitor or two. I was skeptic at first not being a name brand, however zI would highle recommend this product. I almost went with the 24" vs 18.5, but with the protective case I bought with it, they just barely fit in standard size back pack. Clear crisp picture!

Perfect for what I need. Got the 15” 1080 folding option. I really love it. Lost a couple stars for the following: 1. Took me an incredible amount of time to figure the driver needed for Mac. Admittedly, it took me a while to find the QR code on the back. Even then it took some work to get it working. The software records your screen to extend it, So they may be seeing everything I’m doing haha 2. The screens are completely different color haha! If I cared about image I would return it but I only use this for work so it doesn’t affect me. However there is a clear difference between the colors on the top and bottom screen. I can see this when looking at my Tahoe background on iOS. @seller, if you send me a properly working one I will update to 5 stars. EDIT: I finally realized what was going on with the different screen color. I'm not sure if this was in the description when I bought it but MACs do have some limitations with this. For some reason Macs refuse to handle more than one display through a single USB-C. To get around this, you have to install the driver provided that will compress a recording of a virtual screen and send it through the USB to be displayed on the second monitor. This works, but it does create the issues I've pointed out above. The colors will be different from one screen to the other and the quality is drastically lower. It makes everything look a little fuzzy. For the most part I don't mind this because I'm using it for work. However, it's important to know when purchasing. From what I can tell this is not a problem at all for windows. Just Mac which is a bummer.

UPDATE - TO THOSE HAVING TROUBLE GETTING MAC TO SEE THIS AS TWO MONITORS As my original review stated, I had this working with my MacBook Pro as two monitors since I got it. Today, it started doing what others described - could use a USB-C cable to "fill" as a single 2nd monitor but could not get it to show up as 2 external monitors. Turns out that something about the monitor handshaking with the Mac can corrupt the plist (how the Mac "remembers" the monitor, arrangement, and resolution for the next time you use them). This is the procedure that fixed it and brought it back to 2 external monitors: 1. from a Mac terminal window, type, "sudo rm -f /Library/Preferences/com.apple.windowserver.displays.plist rm -f ~/Library/Preferences/ByHost/com.apple.windowserver.displays.*" and press return. You will need to type in your computer admin password. This wipes the cached file of monitor configurations, so it will forget any other monitor configurations you had - so you'll just need to reset resolutions and multi-monitor arrangements if you had any. 2. Make sure that "Fill" mode on the monitor is not on (top side button toggles "Fill On" and "Fill Off" but it takes about several seconds before the change occurs. It needs to be off for this to work. 3. Shut down the computer (not restart). 4. Unplug monitor from computer and from power for 15 seconds. 5. Plug in HDMI cable and plug in power to monitor. 6. Boot the MBP - when it is done booting, go into your display settings and you should see the monitor as a 2nd screen. 7. NOW plug in the USB-C video cable from the lower USB-C port on the monitor (the top one is for power) to the Mac. 8. It shows up as Innoview (2) and renames the other one as Innoview (1) -- two independent external monitors! You can independently set resolutions and arrange them however you like!! The way Mac's do EDID (External Display ID) is a bit different than PC's. That is why this seems to only be a problem on Mac computers. My guess (just a guess) is that the "Fill" mode capability on the dual monitors can confuse the EDID on the Mac and that info is then cached into the plist (memory of the monitor(s)). That is why simply deleting the plist treats it like its brand new monitor connection. BTW, HDMI cannot transmit power, but USB-C tries to negotiate power transfer whenever it is plugged in. That is why I suggested that you start with the HDMI and wait until all is working with that before plugging in the USB-C (and having the USB-C power cord plugged into the monitor before you connect it to the Mac). Original review The hinge is tight - but understandably so - any hinge loosens with age and you would not want this thing closing while using it. The screens are bright and long ago I switched to MacBookPros for color reproduction and these screens look fantastic - They are 18" screens, so they are big in by backpack, but that is not a complaint - it is simple math. If they ever came out with a 17" version that had less of a gap between the two screens, I'd likely buy it - just because my use case doesn't really require the two-sided A-frame capability. I saw some complaints about Apple compatibility - but without any drivers, my M4 MBP works perfectly with these. If I only use a Thunderbolt (USB-C form factor) on my computer, it treats the two screens as one tall screen. But if I use the HDMI and USB-C together, I get 2 external monitors - no problem. I ordered thin HDMI and USB-C Data cables to ensure easy use. Also (and this is physics, not a criticism of the monitors), 2 18" well-lit screens need more power than any laptop USB-C port will provide, so YES, an additional USB power source is required (comes included). I have a small 250W multi-port USB power block I travel with and use 2 of the USB-C ports (1 for the MBP and 1 for these screens). That leaves enough ports and power to charge my iPad, iPhone, and a small multi-device charger for 2nd iPhone, AppleWatch, and AirPodPros - all at the same time. I travel a lot - and now, I have everything I need all together. Setup? there is none - you plug it in.

Un gran monitor, el único pero serían los materiales, pero en general cumple con la descripción

Be careful what you buying as their listings are terrible and contradict themselves. It says 100hz in the listing, 200hz on the image. You have no clue what you are buying! The pros. The monitor appears to be well made and comes with lots of different cables. The screen quality is very good. Cons: Not sent what I was sold. It was advertised as 2560 x 1600 16:10 100hz but I have received 2160 x 1440 16:9 200hz. Went onto Amazon support, no way to contact Innoview there, just do a refund so I will have no monitor that I need for work and now have to mess about doing the return. No way to contact Innoview on their own website as their cloudflare turnstile captcha protection is unable to connect to their own website. From the listing: Featuring a 2560*1600 QHD ultra-clear display and 16:10 No it is 2560 x 1440 and 16:9. I specifically wanted 16:10 for work and had been checking every listing to try and ensure I got that. They all contradict themselves but I thought it saying in the about product section and the reviews all saying 1600 meant that I would get that version. Also my laptop has a thunderbolt 4 USB C port which should power it, it does not. Their own provided brick should power it. It does not. I have an Anker plug I got to charge my laptop so I had to use that. Very disappointed as had to wait for this to come from the US and thought I had done my research as the reviews were saying it was 16:10. The placement of the ports is a bit weird as well as they stick out. would be better being tucked away. Ultimately for a company selling monitors and using Amazon as their own channel to do this they should have their listings correct. I would still like what I had ordered but cannot risk ordering again as I have no idea what I will get as there is no one to speak to, to verify what they will send.

Since the pandemic there has been a major shift of office work to partly working from home. This also meant that sometimes I have to take my work somewhere other than my home office. Having this monitor drastically improved my work efficiency. The monitor is very bright and the resolution is very sharp. As advertised it has the ability to splice the screen if you are a programmer to view long pieces of code. The build quality is really solid where one might have concerns. It has a strong built-in kickstand to prop up both monitors. The hinges are not flimsy at all and there is no wobble for the second monitor on top! Since this is an 18.5” monitor it is actually large enough to practically mount it as part of your desktop suite. As you can see from my pictures that the design has included standard VESA holes that you can make this mountable. Overall a very solid product and would highly recommend

Appears to be as advertised, works well, but it remains to be seen if it is worth the price, the last 32 inch samsung 144hz HDR monitor that I purchased barely lasted 3 years, Not happy about that. I can only hope that I have better luck this time

Okay
