Review on Lenovo Ultra Thin FreeSync DisplayPort 65FAGCC2US 28", 3840X2160P, 75, Tilt Adjustment, Anti-Glare Coating, Wall Mountable, ‎L28U-30, IPS by Richard Nordstrom

This is a decent 4K monitor. Good that an HDMI cable is included. There are two video inputs, one HDMI and one DisplayPort. The monitor stand is fixed. It cannot move up or down or rotate. Assembly is easy and requires no tools. There is no built-in speaker, but there is a 3.5mm audio output. I connect some external speakers. They work fine. The picture quality is excellent. The description mentions a low level of blue light. However, I can't tell the difference. This is the perfect monitor for working from home.
