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.

Update 7/21/22: Still 5 stars. Working perfectly and durable. Carry it around in my pack with 2 PCs (work and personal). Packaging this comes in is so nice and durable that I hated to throw it out - but did, yesterday. The box almost seemed like I should use it for something but resisting my hoarding temptations, got rid of it. Someone mentioned it in a review as being fragile. I do not get that feeling but I suppose if you damaged it, then you might think that. But they still gave it 5-stars, anyway. The tech still seems like magic that video and power can both go in that usb-c cable (if you have a video capable USB-C port which you likely do not, if not having a newer and better computer but still great with the provided HDMI mini connector). ------ I took this out of the box and plugged it into my work PC with the USB-C to USB-C connector that came with the monitor. It came right to life perfectly. Thats it - connected with one cable and it was on. The settings to extend the monitor, duplicate the screen, etc. worked exactly like any second monitor and was super simple (these are settings on your computer - not the monitor). There is sound from a built in speaker which might work if you need sound in a pinch but ANY computer or phone speakers will be much better (my phone speakers blow this monitors speakers away). With my older but still pretty modern Acer notebook the USB-C is not apparently the newest and will only provide power and will not feed the video like my newer Dell work notebook. It still works well, however, by using the USB-C for power and the provided HDMI to mini-HDMI connector. So it just needed 2 cables instead of 1 and it worked perfectly (have it on right this second). It is amazing (to me, anyway) how well this works with just power from the USB-C cable. The quality of the display seems comparable to my desktop external monitor or any screen on a notebook computer. The cover/stand took me a minute to figure out but it is very simple. Just took a minute to see how they meant for it to work but then, super simple. I hope the screen is durable as I plan to carry it around in my backpack with my 2 PCs when I work outside the house.

I love it as an extended monitor! It’s very sleek and the picture is very vivid.

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 :(

Like everyone else who works remotely at times, I end up with countless windows open and find it difficult to do my work on one small 14 laptop screen (not to mention aging and my eyes). I got this because I was traveling and didnt want to take the whole week for vacation. I got EXACTLY what I wanted out of this product. Let me cover the good and the things you should know. All the cords you need to hook this monitor up come with it. I would love to connect it to my computer via USB4 port, but my I use my USB4 port to charge my computer when I travel because the charger is so light and small. So I fell back on the HDMI cord. Came in the package. Boom! Power supply was also included. I connected mine to my computers USB 3.0 port and ran the USB-C cable into the monitor. Power on! Lots bad has been said about the case. I found it very functional. It may not have your ideal viewing angle, but it worked fine for me using the case. It wouldnt fail to capsize in the event of a 7.0 earthquake, but it worked fine in my week-long use. So what do I not like? Well, the monitor is not a high-end one with mind-numbing resolution and clarity. Its good. Plenty good for work on websites, documents, spreadsheets and the like, but if I were a traveling videographer or photographer, Id want something more high end. For me? Worked fine. So for the price I paid, I cant be more satisfied. Sure, Id love one that was larger, but this one fits in my laptop bag no problem. Id love one with a built-in battery so I wouldnt have to plug in the bulky HDMI cord. Id love a better case/stand. But really, this is a solid device, and if you shop for bargains, youre going to have to accept some compromises. With that in mind, I can wholeheartedly recommend this monitor to anyone needing some visual real estate for work, especially while traveling. Its thin, light, functional and it wont break the bank. Thats a lot of winning for such a small screen.

This screen is amazing. I travel for work so it’s perfect because it’s not oversized and a burden and I am able to have a monitor to get my work done more efficiently! I have also used it for gaming on my PS5, and let me just tell you!!! The quality is top tier, especially for the price!

This screen doesn’t have the best picture quality, especially noticeable sitting next to my M1 Air, but it is very functional as a second screen. Being USBC powered is very convenient. With the cover folded over it’s thin and the computer and monitor together fit in the laptop pouch of my backpack.

This is a pretty good monitor for its price. I got it to use along with my sffpc while Im traveling, and I want to use my desktop instead of my laptop. The one gripe I have is the stand, but I just use a 10 dollar ipad stand instead and it works perfectly. This also works with the switch if you use the dock. I also thought the display might get warm, but thats not the case. Overall, I would recommend this monitor if you need something portable and is not too expensive.

Pleased with this monitor for the most part as far as the quality for the price, I paid, and the convenience of being able to travel back-and-forth with my laptop and have two monitors. The only complaint I have is the case that doubles as a stand, although it works great to protect the monitor when traveling it does not work that well to hold it up works better with just a regular cell phone stand

Ive only used it for a few hours, but Ive used it with several devices and it doesnt run hot at all. When I hook it up to power and an android device with the full function usb-C cable it even charges the android device. I was able to take it out and plug it in and just worked, clean and simple. Small, lightweight, good quality picture for its size, and good color.
