Our Verdict
BenQ EL2870U
LG UltraFine 4k
The LG UltraFine 4k is a bit better than the BenQ EL2870U for most uses. The LG has better viewing angles, better uniformity, and slightly better ergonomics. The BenQ, on the other hand, supports HDR, has better reflection handling, and has a flicker-free backlight.
