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.

Works for what u pay
Size: 22
Only reason it’s not a 5star is bc I’m picky it doesn’t have any speakers first of all so don’t go thinking there’s sound refresh rate is what you would think for this price it runs games super well and has decent quality easy to use and pretty bright as well it’s not a curved monitor so the viewing is pretty normal

I live the Quality of this monitor for the price it was so easy to setup She’s up . The quality is everything the box included all cables that connect except of course HDMI but that’s not included. The picture quality and connectivity is amazing I have not complaints. I love that there are enough ports to add additional devices and screen adjustable
