UPERFECT Delta Max 18.5" 100Hz Dual Portable Monitor for Laptop Screen Extender 1080P HDR 360° Folding Stacked Triple Monitor with Stand & VESA for Laptop PC Phone Game Console (No Driver Needed)

The monitor was securely packaged and arrive in great shape. I was impressed at its build and quality. The hinges (3 for this size) are just the right tension for opening, closing and positioning the screens. I bought this because I work from home and when I travel I can't just use my laptop screen. I use it to extend my main screen so I haven't used it yet for anything other than that but since it does so well with that function, I'm sure it will do its job well. I use this with both Mac and Windows systems. The screen itself presents a clear and beautiful picture. I love the size! It would not be something that I would use for my photography editing but that's not the reason I bought it. It would be great for watching videos but, again, that is not why I bought it. I have it mounted via VESA on an arm when at home and I purchased the sleeve for travel. I think that I might use that sleeve for storage but buy one with a strap for traveling with it. It has some heft to it, not enough to discourage me using it but enough to make me comfortable that it is of great build quality. It is not cheap plastic by any means. I find the plug-n-play works as intended and once I configured it as instructed, it was quite easy to get up and going both at home and on the road. After having used it often and in a number of different situations; I would be comfortable saying that if you happen to have one that doesn't function as you expected, then it's a one-off and not the norm. This thing is fantastic and I would buy it again. Everyone who sees it makes a comment about how nice it looks.

Since I transitioned to a full-time remote job, I needed an extra monitor for work, a compact one with a large screen. I already owned a UPerfect 4K, the monitor quality and the build are fantastic, I chose to get the 18.5' dual screen. The dual-screen is phenomenal for work which allows me to have MS Word and Excel open at the same time on different screens. The monitor has a stand and a VESA mount (great for a portable or fixed option), with multiple USB-C and Mini HDMI ports. The setup was easy and the screen is very clear and bright. No drivers required for the monitor to work, single or multi screen. Accessing the menu is very easy using the wheel on the left side on the monitor. The monitor offers a variety of adjustments, beside your Brightness and Contrast the monitor offers a Sharp mode that I found very useful. The game mode is great for FPS and Arcade games. The Ultra HDR enhances your movies and photos while the Eye protection mode helps with long hrs looking at the monitors. The speakers sound loud and clear, and the volume can be controlled using the side wheel. Having one screen on top of the other is extremely functional. It simplifies looking up and down, left and right. The monitor is very portable with solid quality. The dual HDMI input is a nice feature, being able to connect 2 PCs to the same monitor is super useful. I would recommend this monitor to everyone. I use it not only for work but also for my photo editing and music learning.

I recently got the UPERFECT Delta 18.5" 100Hz Dual Monitor. I have been testing it for a little more than two weeks on both a Windows 10 HP Laptop and a MacBook Pro with Intel i7 processor. Here are my observations: 1. Image quality: the image is as expected from an 18.5” screen. I haven’t noticed any backlight bleed or any dead or discolored pixels. I have used it only for coding purposes and the text was clear with good contrast. The displays have good brightness, but note that it does require a separate external power source (other than the USB-C connected laptop) for brighter settings. The brightness can be set individually for each screen. 2. Connectivity: The monitor has three USB-C ports and two micro HDMI ports. I have only tested the USB-ports. 3. Windows: the setup with is very simple with Windows, and the displays are recognized as two screens with a single cable. If the external power source is plugged in, the USB-C connected PC is being charged, which I think is great. 4. MacOS: the macOS setup is similar to the Windows setup. However, in order to have the MacBook use both screens, you will have to connect the MacBook with two USB cables to the display. Including the power source, the means that all three USC-ports will be in use at higher brightness. This, however, is the fault of macOS and an issue that every dual screen with have. Be aware though that macOS does not support multi external displays with M1 or M2 processor. I haven’t tested it with this display, but I would not assume that it is possible to use both screens with those MacBooks versions. 5. Overall build quality: the display seems have a solid build. Since the dual display folds together, with the screens facing each other, they are protected. For traveling,I would still make sure to store it safely. I have a laptop backbag, and the large dual screen fits in.

Good double monitor, the only thing about this that I don't like is that the stand does not work for portrait position, good image, decent lighting, good colors

Vale mucho la pena el costo , la resolucion es excelemnte , me estoy adaptando a la configuracion y acomodo de pantallas , los materiales son de calidad y muy profecional.

1 year and started to breakdown. Below screen doesn’t work fully - only half of it.

The customer service was absolutely excellent. The representative was incredibly patient, professional, and genuinely helpful throughout our communication. The product itself looks great with a very nice finish, but what truly stood out to me was the outstanding service experience. This level of support definitely deserves a 5-star rating. Highly appreciated!
