The LG UltraFine 4k is a decent 23.7 inch, 4k monitor. It delivers decent overall picture quality, with very good low input lag and decent motion handling. Like most IPS monitors, it has great wide viewing angles. This monitor has outstanding peak brightness and excellent gray uniformity, but it has mediocre reflection handling and doesn't look as good in a really bright room. Unfortunately, the backlight has a strange flicker frequency, which results in noticeable duplications in motion. It also doesn't look as good in a dark room, which is typical of IPS monitors.

This monitor is marketed towards Mac computers and only has USB-C inputs, which might be an issue for some PC users. This monitor doesn't have any controls, either, and no on-screen display, which is a bit strange.
