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

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.
