What people are saying

Rated 1 out of 5 by from Defective Monitor and Horrid Support I bought this monitor 2 months ago. Now the monitor flickers continuously. Contacted support for assistance. They requested I pay for my own shipping box so the monitor may go for repair. I suggested LG Support ship me a new monitor so I may send the defective one back using the new monitor box. LG refused. I simply couldn't wait for the repair time and round-trip shipping time as I need a monitor for work. This would be the last time I purchase any LG product. Unbelievable. In my more than 20 years of using a computer monitor, I never had one that went bust in 2 months.
