The LG 34WK95U-W is a good 5k IPS LED monitor with good picture quality. It can get very bright in SDR, and it can display HDR content decently, but unfortunately, when viewed in a dark room, blacks will look grayish due to the mediocre contrast ratio and the bad local dimming. It has a large size screen and excellent resolution. It has a low input lag that makes it very responsive to your actions, but it's not flicker-free and doesn't support any variable refresh rate implementation to please serious gamers. Sadly, there are multiple reports of image retention on this monitor, which is a problem if you need it for office work or content creation.

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.
