Review on NIUTO Portable Touchscreen Extender Computer Compatible 14", 60Hz, 便携, 140-4K, HDMI, IPS, 4K, HD by Michael Dominguez

Very good 4k monitor for various purposes. The DPI is very high, so the picture quality is excellent, but 14 inches isn't very big, and even when the display is scaled to 1920x1080, everything on the screen is small. The recommended scaling is 300%, which is only 1280x720, not very useful in my opinion. The touchscreen is actually rendered as a trackpad in Windows, so it only works on the primary display. This is not a problem if you use this screen to clone your main screen. , but if you're using it to extend your desktop like I did, it's not usable. Well, it will still work, but it won't align and you won't like it. I use it as a dedicated screen. for my Apache Labs SDR ham radio and it works great for that. I paid about $220 and I think it's good value for money.
