Our Verdict
Dell U3417W
LG 43UD79-B
The Dell U3417W is a bit better than the LG 43UD79. The U3417W is a bit brighter and has more vibrant colors due to the better color volume. The U3417W has better ergonomics and it's easier to adjust to a comfortable position, whereas the LG 43UD79 has very limited adjustments. It has lower input lag and the larger screen provides more screen real estate, which is good for productivity.
