Cooler Master Tempest GP27U 160 Hz Mini LED 4K Review: Bright, Colorful And Speedy

As an image-quality geek, I look for one thing above all when evaluating displays —contrast. Dynamic range, the difference between black and white, is king. Get that right, and everything else falls into place. When CRTs and plasma panels left this planet, so did deep contrast. Self-emissive technologies can turn off individual pixels to produce a true black. LCDs cannot do this, but there is hope.

Today, we have LCDs that can do a passable imitation of a plasma or OLED panel. We know them as Full-Array Local Dimming (FALD) panels, and they come in two varieties: LED and Mini LED. That second one has become more significant of late. Though a premium technology, Mini LED has expanded the number of dimming zones possible. More zones mean better control over more and smaller pieces of the image.
