The monitor has two USB-C ports, and a mini-HDMI port. The HDMI cable connects to the HDMI on my laptop. The monitor can be powered by the USB port on the laptop without using the USB power adaptor that came with the monitor. Monitor quality is good - clear with matte surface. The speakers on the monitor are a bit weak; I just have the audio come from the laptop. The case feels metallic and solid. The cover that came with the monitor is flexible and functional for both screen protection and as a monitor stand. Overall, a great portable monitor especially at the price point.

Before you read the issue I had below I would like to add that the seller saw this review and contacted me directly. They asked me a few troubleshooting questions and when they saw that I actually had a hardware problem they sent me a new monitor and it works perfectly. So thank you for the great customer service and this is a great product now that I have one that works correctly! It works fine on my Dell laptop if I use the USB-C port for power and the HDMI for video. But I really think it should work with just the USB-C alone. But it doesnt. It just powers up and says no signal. I even tried it on my sons Nintendo switch to see if maybe it was my computer was the problem. Doesnt work on USB-C on the switch either. Powers up but says no signal. Im sure I could use the switches docking station and use the HDMI out and it would work fine. But thats not the point. Was advertised to have a fully functional USBC port. That could be used for power and video. So either mine is malfunctioning or its false advertisement.

I am using this as a 3rd monitor and it works well. I had a small learning curve with setting it up, the directions are a bit confusing if you aren’t fluent in the technology but I got it and it works well. I haven’t tried traveling with it yet. I would recommend to a friend for sure.

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 :(

Bought two of these monitors to use while working remote on the road. They also work great for streaming with an Amazon Fire Stick. I purchased a mini HDMI to HDMI female cable and then plug the Fire Stick into it. Since the monitor has speakers, you can watch and listen to shows. Great for road trips.

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.

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

I have this for a year now. It’s works fine. I used this in my two recent trips outside the US and I did not encounter problems using it. I have this in my carry-on luggage, no issues going through TSA (it’s like tablet). The screen is also wider than my laptop so I typically used this at home as tertiary extended monitor.

I work remotely, but when I travel and just have laptop having this second screen is great! It’s so much better and bigger than I imagined. The picture is clear and easy to connect and set up.

**Update**I loved how it got power and display by just one type c cable. Picture was really good and had no noticable delay. The case it came with is not very sturdy and will not protect the screen...I literally used this screen once and the screen cracked while in my backpack. *The company reached out to me and offered to replace the monitor at no cost. I was very happy with the outcome. Id probably recommend a case to keep this in.
