I use this monitor for work and I don’t need to turn my face to see the edge of the screen. Absolutely love it! Bright enough but not too much to bother my sight! Nice color, monitor not too heavy but still good quality. Lots of value in this purchase! Highly recommend to my colleagues and friends!

Screen perfection

This screen was perfect for my son’s gaming, the resolution, sound quality, and color accuracy is great. The gaming capability runs quick and refresh rate is fast.

Monitor stopped working after a few months

I work from home. I bought 2 of the 27’ monitors at the end of April and loved them. I used them for 2 months before going out of state. I came back a few days ago, everything was working until one of the monitors suddenly went dark and it won’t turn back on no matter what I do. The laptop does detect that it’s plugged in.

Exceptional

Size: 22, Size: 22

Great quality and price. Monitors are exceptional. Would buy again without question. Screens are quite resilient, great picture. I bought three and use them in a multi Monitor setup for my work laptop, I needed something to view wireing diagrams and scan tool information qt the same time. If your a Service Technician looking for a multi Monitor set up would strongly recommend this Monitor.
