What people are saying

Rated 5 out of 5 by from Great product Nice picture. Sharp, clear, no dead pixels. Adjustable stand is welcome. Like that the monitor is color calibrated so that I don't have to adjust it. Very easy to set up. First LG monitor I bought and I am not disappointed at all.

Rated 5 out of 5 by from Great Monitor Had the monitor for several weeks. Resolution and contrast excellent. Streams 4K perfectly. Best monitor I have ever purchased. thinking of buying a 2nd to complete my work space.

Rated 5 out of 5 by from Extremely Capable Versatile Gaming Monitor HDR is beautiful and while the monitor isn’t extremely bright it is suitable for most. Free sync extended mode provides smooth gameplay. Next to my first generation 4k monitor it is clear that the IPS Calibrated LG colors are more true to life. The old monitor now appears washed out. I am very pleased with my purchase and would recommend this panel.
