U2720Q, Recurring Temporary Red and Green Vertical Lines

Question

Bought this amazing display today and carefully assembled it as instructed. While using it i spotted a green line, and then after some time it disappeared. Then re-appeared and so on. After a while a red line showed up and was able to see it through the OSD. What should i do now ? Thanks in advance

stunner349,

Disconnect the U2720Q from the PC video card cable. Run the stand-alone BID (Built-in Diagnostics) page 53. Do you see the lines?

Did you purchase the monitor from a reseller? The monitor is not registered to your name. You can fill out the online warranty and transfer form here.

Yes, I do see the lines in the Built-In Diagnostics. I bought it from Amazon so replacing it. Thank You Jesse!
