I bought a U2415 monitors last June (June 11, 2015) from Amazon. I have used them good but today one of the monitor was flickering. I replaced the monitor with good monitor the good monitor was OK. I tried the inputs HDMI1, HDMI2, mDP, all were same result(flickering).
Amazon only accept returns in 30 days from the purchase date. What can I do?
The problem monitor is :
S/N: CN-OPVJVW-74261-581-05ML T
Date of Mfg: August 2015 90-130
You may get an exchange through Dell. Go here. Scroll down to, Monitors without a service tag number purchased from resellers (Amazon, Best Buy, Buy.com, Cost Co, Walmart, Sams, other online store, etc.).
