Review on UPERFECT Portable 4K UHD Brightness FreeSync 15.6" Monitor, Frameless, Built-In Speakers, Glossy Screen, Model: MDS-156A23, HD by Devin Rogers

So far I've tried the uPerfect 4K Monitor with my Roku, Raspberry Pi and Apple MacBook Air M1. I bought this primarily as a monitor for my RPi. The picture quality is very good. Fonts are clean and easy to read. Much better than my previous HDMI monitor. The video streaming quality was good, but to be honest I didn't use it much for that. Stereo sound works well for the small speaker size. Using the monitor with my MacBook Air M1 works well, but if you have a yellow background on your desktop, you'll find that uPerfect doesn't quite capture the intense yellow that would appear on an MBA screen. I decided to test it with Neuvideo's ANI-4KANA-L HDMI analyzer, and UPerfect Yellows performed as well as both of my Samsung TVs. All other colors look bold, which is what I expected. The screen was a little less bright (75 lux) on the right side of the screen than the center or left, but that's not noticeable with what I'm doing. The packaging comes close to Apple in quality. uPerfect obviously took the time to make a really good box. All cables are in their own resealable bags. The cable doesn't look cheap and all came with connector covers. (All HDMI cables have passed analysis cable tests). The small instruction manual was concise and well written. The stand/cover is way better than some other portable monitors I've seen. The metal frame of the monitor is comfortable to the touch, heavy and rigid. I don't think it's made for playing around with, but it should be perfect for everyday use in the office or lab. I would give this portable monitor 4.5 stars and would definitely purchase another UPerfect portable monitor if the need arises.
