    Very good, economical, and ideal for everyday use, movies, and gaming. The price is very good, with the main advantages being the good contrast of the VA panel and the curvature that improves the viewing experience in a small size. The kids were thrilled with joy when they saw it

    Excellent screen with crystal-clear image, vibrant colors, and clarity. I use it for daily office work as well as casual gaming. Very useful that I connect the laptop with a type-c cable for image transmission, while it charges at the same time, so I don't need to have a thousand cables on the desk!
