Wow. With this price, the color quality of this monitor is amazing. Most surprising part is the speaker! The sound is so nice! My son use it to link his Chromebook to goto YouTube and enjoy to classic music played by Berlin philharmonic, wow!!! This is really a wonderful monitor!! Really a great product.

Nice monitor great value

Size: 24

I liked this so much I got 2. Nice size for a monitor, looks good, works good. No sound, camera or mic, so I bought a speaker and camera on Amazon too.

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.

Great product and great price

Size: 22

I think the negative thing I can highlight is the pixel dentist isn’t that high so it doesn’t look as crisp but this is a great budget option when you are in a hurry (like me) or simply need a screen that does its job. I use it for home office and it’s more than enough.
