InnoView 23.8" FHD 100Hz 100% sRGB Dual Monitor 315°Adjustable Monitor Extendrer for Windows Mac w/HDMI Type-C Work Gaming Office Triple Monitors

This dual 18"m 2K (2.5K) monitor is superb. I initially paired it with an older Surface Pro 6 and was not able to get it into Extend mode like a wanted. This was due to limitations of the Surface Dock video controller. I ultimately paired it with a Surface Pro 10 and it works perfectly in all display modes. I am also using a single Anker 130W Charger to power the Monitor and Surface. The display draws 21W at 100Hz, full 2560x1600 resolution, and 100% brightness. I have not been able to power the monitor through a single USB-C cable from the surface so separate USB-C is needed for display power (not unexpected). I am also able to power the monitor and laptop using a Baseus 100W, 20AHr Power Bank which shows is using 34W which suggest that the video USB is providing about 14W of power. On this Power Bank it reports that it will las about 2 hours. The monitor refresh rate does not have a big impact on power draw, but the brightness has an almost proportional impact on power. The kickstand is very versatile, and the monitor is very secure in any configuration. Even standing stacked vertically they are stable. The folding hinge is smooth but firm, there is little change of it slipping; perhaps after a few years they may start loosening but that remains to be seen. The screens are large, bright, and crisp. While 4K might be better for photo/video editing, these are perfect for normal business use and CAD work as I intend to use them. I bought a separate single 4K monitor for photo work. Out of the box the color/contrast closely match my Surface (at default settings); I did bump the monitor brightness up from the default 80% to 100% for a perfect match. I found a 17.3" Monitor Sleeve from CaseDeer that fits like a bespoke case. The monitor in the sleeve and my Surface drops perfectly into the laptop compartment of my TUMI fold-top backpack.

I purchased the new 23.8 inch 2k dual displays. While it does run as advertised and is the first of its kind, it is has some issues. Device charging does not work with a 100W charger even though the instruction manual specifies 100W (my laptop reports charging but uses far more power than it draws). In the dual-screen extended mode where both screens appear to the computer as one, changing brightness info via DCI from your computer only changes the top display, and the bottom screen will bug out and require a power cycle if trying to connect the computer and you your computer can only handle one more external display (not two). There is also a constant buzz/noise which could be a defect - I'm not sure if it would decrease the lifespan. I've had the connection cut out out a few times over HDMI - USB-C is more stable generally. Pros are that the stand is strong (it needs to be as this thing is massive!). Both screens are bright and 2K and the connection is pretty stable aside from the bottom monitor issues in some cases above. Keep in mind that this this is so big that you need the bottom monitor angled at maybe 25 degrees or more to get the top monitor to be eye-level, which takes up more desk space. Another generation or two to nail out the bugs and this should be pretty awesome, but this seems like a bit of a beta product still.

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.

I’m extremely pleased with this dual portable monitor. It provides ample screen space to support my work needs while packing down small and using minimal desk space. I also take it with me when traveling, and it works perfectly in hotel rooms where desk space is typically limited. I already own several InnoView monitors and have been happy with their quality. I plan to purchase their 27" dual-mode 4K monitor next. Highly recommended for anyone needing additional screen space and flexibility.

I am very happy with these monitors.The displays have a really sharp image. The stacked design leads a lot more space on my desk. It was more complicated than I expected to connect the monitors to my computer. I daisychained a VGA to HDMI adapter and an HDMI to USB-C adapter to connect the top monitor to the VGA port on my computer.
