Our Verdict
Dell U2715H
LG 43UD79-B
The Dell U2715H is better than the LG 43UD79, unless you want a large screen. The Dell U2715H has much better ergonomics and can easily be adjusted for an optimal viewing position, great if multiple people will be using the monitor. The LG 43UD79 has a much larger screen and higher native resolution, so you can see more details and it is easier to multitask.
