Our Verdict

Samsung CHG70

LG 27UK650-W

If you've got a bright office and work closely with others, the LG 27UK650-W is a better choice, but if you play games in a dark room sitting directly in front, then the Samsung CHG70 is a better choice. The LG 27UK650-W has better resolution and much better vertical and horizontal viewing angle, which makes it better for office use. On the other hand, the Samsung CHG70 has better refresh rate and input lag which makes it better for gaming. The Samsung CHG70 also has better blacks.
