UPERFECT18.4 Inch Portable Monitor 4K Ultra HD 3840x2160 with HDR/100% sRGB, Aluminum Case, Matte Monitor IPS Screen with Mini HDMI/Type-C Port/VESA Mountable, Extend Monitor for PC/Laptop/PS/PhoneEnergy Label

I purchased two of the Umax 22 displays and they have worked perfectly as a dual monitor setup with my Mac Mini M4. The scaling works perfectly and images / text are very clear and nicely sized. The build is good and in their packaged state they come with three cables (usb c x2 and a mini hdmi x1), power supply which accepts the usb c as well as a few 4mm vesa mount screws. The tilt stand on this works well and is tight meaning you can really get some step angled viewing positions before the leg gives way. I purchased some Hagidis u angled adapters off of Amazon so that I could get the displays tight up to each other. I use these for office work / some recreational music production / browsing (I have not tried gaming on them so can’t comment) but what I will say is they are plenty bright enough even being sat underneath a window I have not had issues. The before and after sales customer service was outstanding via Amazon and directly via Uperfect email. Please think about it when sending queries to them that they are not necessarily in the same time zone as you so to get a response not immediately is completely reasonable as most companies do not have 24/7 communication. Really really happy, thank you

The media could not be loaded. Great monitor. Huge, clear and bright portable screen that’s already something I am relying on for work. For spreadsheets the screen is so helpful. It was easy to setup - hdmi connection with simple configuration and is far better than my Lenovo laptop screen. The little kickstand means it’s the complete package and sits on my desk as an essential workbook. Very pleased customer.

It's a reasonable size to work on, especially with the laptop as a second screen. The resolution is good enough for text based work. It's nice and thin and feels good quality.The one downside is that it must be plugged in to get any sort of brightness. When is just plugged in to my dell laptop it's so dim it's unusable. Even when it's plugged in to a socket there is no way it could be used in the sun.

The media could not be loaded. I’ve been impressed with this UPERFECT 21.5” 1080P Full HD monitor. It worked straight out of the box once I had connected my MacBook Pro to this monitor via a HDMI cable and a USB-C cable for the power.The monitor has a nice finish and looks good when it’s both on and off. It came with a HDMI cable and two USB-C cables. There was also a charger supplied for a USB-C cable and an instruction booklet. It also has VESA capability (75mm x 75mm, M4*5mm), which is extremely useful as well as a kickstand for portable settings etc. There is also an audio jack interface (3.5mm).The 21.5” screen size seems to just be the right size to complement my 14” MacBook pro laptop. I also have the UPERFECT 15.5” 1080P Full HD VERSION monitor and these two complement each other very well. The colours in this 21.5” monitor are nice and sharp and I’m very happy with this monitor and would highly recommend it. The customer service so far has been very good.

It works very well with my macbook pro m3. Solid build and elegant design. It looks like a 15 inch laptop when folded. The customer service is very professional and helpful resolving triple monitor setup. Overall I'm very happy with this dual screen monitor

The media could not be loaded. When I was unboxing this, the first thing that struck me was how incredibly thin this thing is! On par with laptop displays kind of thin! Down the lower back of the monitor it bulges out a little to give you access to the ports and controls, and also a very nifty kickstand that makes positioning a breeze. There are also little rubber pads on the bottom of the monitor so it doesn't scrape up your desk.The display itself packs a very impressive punch, I've never seen a touchscreen so smooth at 120Hz. I have had no issues with brightness or colour reproduction and I absolutely love that it's so easy and portable to use with just one USB-C cable from my laptop.The control scheme is quite cool and gives you access to a comprehensive menu that lets you enable FreeSync and HDR.Overall, I've never seen a touchscreen monitor so capable and sleek, and it is absolutely worth the (relatively cheap) price.

good concept, but the screens overheat in 15 mins and turn off.... so not so great, will be returning

Great monitor, and quick and helpful customer service! Thanks for your help
