Review on Usparkle Portable Monitor Type C Speakers: 15.6" HD IPS, 3840X2160P, Anti-Glare with Blue Light Filter, Built-In Speakers - GS156AM1 by Jay Kidd

I would say that this monitor is only useful for productivity. As another reviewer might have mentioned, the screen is responsive to gaming. The slow response time of this monitor is a problem for gamers. DO NOT take this for gaming. This causes blurring/ghosting and something annoying in games. That being said, this monitor is actually pretty good for things like video editing (which is what I mainly use it for), spreadsheets (productivity), and photo editing. The picture is very sharp and clear, it's 4K after all! That's no lie, and for the price, I was really surprised that this display actually has a 4K resolution. Overall, I recommend this to anyone who has a laptop and wants a second screen for their home setup. While it's portable, I don't know if I'd want to use it at Starbucks with coffee in front of me. It's definitely useful and there's a lot you can do with the monitor. I recommend it!
