LG 27UD58-B vs LG 27UD68-W

You'll not need to spend time calibrating this monitor because its out-of-the-box color accuracy and gamma tracking are high enough. The monitor's average color inaccuracy dE measures at only around 2.12 - too insignifficant to be spotted by a human eye.

You'll be hard pressed trying to find a cheaper 27-inch 4K monitor that offers the functionality and the high picture quality of the 27UD58-B. In this price bracket, the most common 4K options are usually armed with the old-fashioned TN panels that don't look as good as an IPS panel of the LG 27UD58-B.

The 27UD68-W offers decent performance in bright environments, where it can get vivid enough to fight glare. The monitor can sustain the brightness of around 310 nits which means that the light coming from doors and windows will not be able to overpower the light that the panel emits.

Unlike some other IPS monitors, the LG 27UD68-W doesn't suffer from the dirty screen effect that is usually caused by a panel's poor overall uniformity. Large objects and panning shots look uniform on the screen. The panel's overall uniformity measures at 3.11% dE - a solid result for a monitor in this price bracket.
