Our Verdict
BenQ EL2870U
BenQ EX2780Q
The BenQ EX2780Q is much better than the BenQ EL2870U. The EX2780Q's IPS panel has much better viewing angles, contrast ratio, and black uniformity. It also has a much higher refresh rate, as well as a lower input lag. On the other hand, the EL2870U has a 4k resolution, which is better for productivity, and better color accuracy out of the box.
