The LG 43UD79 is a decent 4k monitor with an IPS panel. The high resolution and large 43" size is good for multitaskers, as it allows viewing multiple documents side-by-side. The IPS panel has a low native contrast ratio so blacks appear gray in a dark room, but the image also remains accurate when viewed from up close. The motion handling is decent, although it doesn't feel as fluid or responsive as other monitors with higher refresh rates.

We buy and test more than 30 monitors each year, all of which we purchase ourselves, without cherry-picked units or samples. We put a lot into each unbiased, straight-to-the-point review, and there's a whole process from purchasing to publishing, involving multiple teams and people. We do more than just use the monitor for a week; we use specialized, custom tools to measure various aspects and deliver objective, data-driven results. We also consider multiple factors before making any recommendations, including the monitor's cost, its performance compared to the competition, and whether it's easy to find.
