Fantastic portable monitor

I bought it mainly to use as a larger display for my Steam deck. It sits under my large ultra-wide monitor so I can play or watch Netflix in between work. It's great for that and for taking a multiplayer game with the kids on vacation or watching videos in a hotel room. I've also used it as a second monitor for my Chromebook for work. There just isn't a good Chromebook RDP app out there, so that's an issue, but the monitor itself worked fantastically. It actually worked better on Steam Deck…

*Edited* Out of specification, faulty HDMI cables

Update2* review revision. The manufacturer contacted me again and asked if I would like to check the panel again. They made another batch of goods and offered to ship them to me. The new monitor and packaging were different. HDMI cables were different. I connected the monitor and found that the HDMI cable is working properly. The monitor itself has become much better. Colors no longer have a bluish cast. Text is crisp and colors are represented very well. The monitor automatically detected the…

KYY great customer support

I previously had a problem with a missing cable, the KYY support team reached out and offered to fix it. I want more sellers to have better customer service and take care of the buyer after the sale is completed. My years on this planet have taught me one thing: the way you treat a customer is your own way. Thank you KYY The monitor itself is amazing, well made from metal rather than plastic. It has a matte display that doesn't suffer from annoying glare like glossy screens, but colors are…

It was great...then it stopped working

It took a while for this monitor to properly set up my new 4K Apple TV. This menu is a bit awkward to navigate, and it looked very desaturated, like I was looking at it through a foggy protective film (and yes, I removed the protective film from the screen they send it from). It looked a lot better after going to HDR, but now it has two major problems. The first can be seen in the video. It just turns on and off every 5 seconds and there is nothing I can do to stop it or try to fix it. I'm not…

Inexpensive portable monitor

I love this portable monitor! My 2017 13" MBP fell victim to flexgate and I was unable to use the internal monitor. Hoping that Apple will one day add 2017 models to their overhaul program, I decided to check out this one KYY 4K K3-3 model to buy I use it as an external monitor to have some portability otherwise the MBP would be tied to my office monitor Color is sharp and resolution is as advertised My only complaint is the short power cord , but I managed to solve this by daisy chaining the…

Good portable display, pay attention to the power of your power supply

I have several portable monitors that I use and I wanted to try switching from the 1080p that I have. I use them to play Fortnite and other Switch games. VERY IMPORTANT: If you don't have an outlet, get a 3-5W power adapter AND a cord (yes, cords are important too). Normal charging does not work for this. Not even your fancy phone charger. I had a lot of problems initially because the cable that came with it is so short. That being said, I had an issue with the first monitor out of the box…

Monitor died after 6 weeks

*UPDATE November 9, 2022 *Customer Service (CS) contacted me almost immediately after posting my issue and resolved it very quickly. I had to send them a video of a flickering monitor. They immediately offered to send another new monitor. However due to my location (outside the US) they couldn't send me a new part so they had to give me a full refund and I have to place the order again which is the problem - I haven't checked to see if the refund went through yet. I think CS is great - but it…

Promising, but not enough

When I first unboxed it I was really impressed - it looks like cutting edge technology, well built, looks like a really good portable monitor. It has all the features you need and it looked like a great product. When I first connected it to my 2018 MacBook Pro I was disappointed - I thought it was broken because the display was unstable - the image appeared and disappeared constantly, about a couple of times a second. I was wondering if this is because my laptop can't drive multiple external…

Impressive in my opinion

I'm really impressed with the picture quality of this portable monitor. Everything you need is included, e.g. B. HDMI to mini HDMI cable, USB-C cable and USB-C power cable. It even comes with a lid/magnetic stand! My laptop is a bit older so I connected a USB-C cable to my laptop for power only and an HDMI to mini-HDMI cable for video/audio. This allows me to have a truly portable dual monitor experience even when I have nowhere to power my laptop and portable display.

Nice and clear - my new review

Use it when traveling, the screen is nice and big - it ends up showing 125%, just like my laptop and can be used with just a little squinting ;) The monitor itself is very light, it almost feels like as if it were lighter than the lid! The lid takes a little getting used to, it has a magnetic mount, but I find it comes off too easily - it would be better if there was a built-in kickstand like the Surface Pro. Super beautiful and practical when there is a USB-C connector, a cable for signal and

Fantastic monitor! Customer service is outstanding!

The first monitor I received had a stuck pixel in the middle of the screen. I wrote a negative review about it and sent the Revain monitor back. The company contacted me and immediately sent a replacement. The replacement monitor is perfect, no problem at all! I was very impressed with the quick response from the company. Anyone who buys this monitor can rest assured that if there is a problem it will be taken care of immediately and the company will do everything possible to ensure that you…

Good screen in my review

I bought this monitor to watch movies from my phone on a big screen because I have Netflix on my phone but no internet at home because I live where there are no network services yet. Judging by my photos, it has an excellent screen quality. You can definitely see the fine details. It has decent sound, but if you want it louder you can just plug in a speaker. The protective case doubles as a stand that can be adjusted to suit your viewing needs, and when you're done with that, simply fold back…

Very clear and bright display. Extremely wearable.

I have 2 KYY 1920 x 1080 15.6 monitors and after using them for a full month while traveling I can say with confidence that text is much clearer on this 4k display. While the FHD version had no issues when I compare them side by side, this display has less of a screen door effect than my 2650 x 1440 Thinkpad display or my 1920 x 1080 KYY monitor where text looks very sharp - I have one Photo comparison attached. Portability On the other hand, 4k and FHD monitors are the same size and any…

Great easy to use monitor for busy people

This is an amazing product with great customer support! We bought two of these monitors a few months ago and we love them. Its compact profile and easy-to-integrate USB-C connector make this monitor a great choice for people who travel or want the convenience of multiple displays without the inconvenience of a power adapter. Customer support is really great too! Two months later, one of our monitors had a cracked pixel crack. Since Revain couldn't help, I contacted the seller. They sent me a…

Great quality, feel a bit cheated

I actually have 2 KYY monitors. The previous one I bought was about $100 cheaper and about the same quality but had more items inside. The reason I gave it 4 stars instead of 5 is that while it does come with a power cord, it is very bulky and short. I can say that you can use USB Type-C if you don't want to use the included power cord and it comes out of your laptop's power supply. The previous model I ordered came with a USB Type-C cable and screen protector, but this model didn't. Turn it…

Just amazing in my rating

This little monitor is just amazing. It worked the moment I plugged the USB-C cable into my laptop's USB-C multiport port. The picture was great and required minimal setup, easily achieved between the Windows operating system and a toggle switch on the side of the monitor. I've included a video showing samples of some of the colors this little workhorse is capable of. Note that there is some camera glare that isn't there when viewing the monitor in real time. They pack easily into the backpack…

Pretty decent monitor, everything else is bad

Firstly, this product has almost everything I need and the only downside for me is that it is not compatible with 144Hz, OLED, touchscreen or VESA as a monitor. The image quality is decent, the brightness is definitely sufficient and the durability is not a problem. At the same time, the stand/case is hot crap. The magnets are not working and appear to be misaligned. I'm not sure if my block is a design flaw or a genuine defect. In any case, nothing really sticks and the stand/case is very…

An almost perfect match for the Creator laptop out of the box

I tried another brand of portable monitor that didn't have Adobe sRGB and was very dim. It was awful and unusable next to an Acer ConceptD laptop no matter how much I fiddled with the settings. This KYY monitor is almost perfect from the start, even at 50% brightness. Highly recommend if you want to be portable but need color accuracy.
