Great monitors
Size: 27 inch 100Hz
For this price point, I wasn't expecting the quality of these monitors. they are large, do not emit a glare and the picture quality is very good. While it might not be for gaming, going to these larger monitors for work has made it far easier with less eye strain. My co-worker and I are very happy with the quality.

Good work monitor
Size: 27 inch 100Hz
Bought this to replace my Dell that crapped out unexpectedly. Glad to be paying 1/2 the price of my Dell now. Fast easy setup, solid build without the weight. Comes with solid stand, cables, allows up/down tilt. Good color and blackness. Good refresh rate. Cannot complain as the primary monitor in a 3 display setup. Perfectly adequate running games for a casual gamer.

EXCELLENT MONITOR FOR WORK!
Size: 27 inch 100Hz
I recently purchased the Phillips 27" monitor and it has exceeded my expectations in every way. For the price, this monitor delivers outstanding performance and quality. Picture Quality-The Full HD display is incredibly crisp and vibrant. Colors look natural without being over saturated, and test is sharp, making long work sessions easy on the eyes. The thin bezel design also gives it a modern, clean look and makes it great for multi-monitor setups. The design and build of this monitor is sleek and minimalistic. It's lightweight, slim, and fits beautifully on my desk without taking up much space. The stand is stable and the overall build quality feels solid and well made. The monitors low blue light mode makes it comfortable to use for hours at a time. Setup was extremely easy-just plug and go. If your looking for a monitor that delivers impressive clarity, smooth performance and looks stylish without breaking the bank, then this monitor is a fantastic choice. Highly recommend!
