    Rated 1 out of 5 by Queen Jewels from Double Trouble I purchased x2 monitors. The housing unit that hod the power cord in the monitor had a shortage in both units. The inspectors after the units were completed passed the units knowing or not a proper inspection was done. This was a manufactory problem. I was highly disappointed that both monitors had the exact same problem.
