I purchased a KYY 4K monitor (3820x2160) for my personal use around the house or on the road (flexgate got my 2017 MacBook Pro [MBP]). But for my daughter in college, I got her this inexpensive, yet excellent monitor from the same manufacturer. Like my first KYY monitor, this one is well-built, lightweight, and simple to use for her dorm room or the library (it might be a little too much for a classroom or lecture hall). The monitor does not have an internal battery and the power cable is a little too short in my opinion; however, when I connect the included USB-C cable to her MBP, she was able to get about three hours of use before her MBP battery died (it’s an old battery). KYY’s awesome customer service reached out to me after my purchase and asked for any suggestions. I told them that I’d like to see a VESA mount for when not mobile; a longer power cord; and an internal battery. Even without these conveniences, my daughter is still able to do what she needs to do off the MBP battery. If KYY rolls out another monitor with the above features at their reasonable prices, I’ll purchase from them again.

I bought this a year ago since I work remote and travel a lot - this was the best quality I could find for the lowest weight. It has served me well, but within one month the USB-C port stopped working for anything but power - it would not transfer picture. For that first month it was great because I only needed the one chord, but since then I have needed a power chord and the mini-HDMI-to-HDMI chord (which you cant find in tech stores by the way, only on Amazon). About 6 months after purchase, I started to notice that the picture chord would only work if held a certain way, so I always had to prop something extra under the connected chord to get a picture. And finally today, 11 months after purchase, the picture stopped transferring altogether - Ive tried both chords I have now its just a nice big paperweight. I think Ill buy it again because it was very useful for that year, this time I will just use the support as soon as something stops working so hopefully I can keep it fixed within the warranty.

My company does live streaming sports and special events, multi-camera with graphics etc. I needed something portable to bring to preview these elements as well as audio, both for me as the director, and for on-air voice talent. This monitor fit the bill well, its portable, easy to power, and good enough picture quality to get the job done. BUT - it died after just a few months of use. Probably only had it on 4 or 5 jobs. It refuses to detect any HDMI mini inputs, and of course Ive tried multiple cables on multiple input devices. It powers down and you my friend are dead in the water... Reached out to the vendor, who suggested testing with - you guessed it - multiple cables and input devices, and when I reported just that back to them they basically stopped returning my messages. The unit is supposed to be covered for a year, but good luck getting them to honor that. I take good care of my gear, as its the source of my income. If youre just giving it to your kids to play videos on, you might have a better experience. Good luck! UPDATE: They did finally reach out again, and are sending a replacement unit - Ive upgraded to 3 stars.

I had a few issues on my first purchase. I have never experienced such amazing customer service in my life. Amazing! Thank you everyone at KYY

Great monitor for what i needed, i use it wirh my galaxy s20, switch and qindows laptop. Only down side is that no built-in power supply so majority of the time need 2 cables connected.

Like most of you reading the reviews, I know the price might make you concerned that it is not a quality screen, so I set my expectations to be average. But in person, it is a very nice screen. Not top of the line. No dead pixels. Minor bleed in a dark room around the edges, but not enough to bother me. Color is vibrant, , black is dark with no washout, Crisp text, runs a solid 1080P, and very bright. Includes cables. Cons; HDR is a mess and cant be used for me. Case is a little flimsy but is okay because it was free, no VESA mount on the back. Well worth the money and I am glad I bought it. Time will tell on the durability, but if it makes it a year with everyday use, I will be happy.

KYY screen had me excited the first few months and as I continued to use the screen continued to get worse and worse. My screen now has green flickering lines in the bottom with fuzzy pixeling throughout the screen all the while the screen continues to blackout because micro hdmi plug on the screen.

The device is easy to use and set up. HDR works really well as well and can run games like Minecraft and COD on my Xbox without an issue. Only reason not 5 stars is it has a slight discoloration on the bottom left corner. I’m guessing from being dropped when shipped.

This is a very well-made product. I like the cover it comes with. No technical issues since purchase.

the monitor itself is fine but the only way i could make it work with a nintendo switch was to have the nintendo power adapter plugged into a wall. it doesn’t work with a high power battery pack (more than the 2.5A the manual suggested). the speakers aren’t very good, very tinny, but i’d expect that from a monitor. especially at this price wish it worked for me :(
