Our Verdict
LG 27UD68-B
LG 27UD58-B
The LG 27UD68P-B is better than the LG 27UD58-B, but overall, performance is very similar between the two. The 27UD58-B has a fixed stand that has extremely limited flexibility, whereas the 27UD68P-B has a telescoping stand and can rotate between a portrait and landscape orientation. The 27UD58-B is brighter as well.
