Our Verdict
LG 27UK650-W
Dell S3221QS
The LG 27UK650-W is better than the Dell S3221QS. The 27UK650-W has much better ergonomics, wider viewing angles, and gets a lot brighter. It also has significantly faster response time, making it a better choice for gaming. However, the Dell S3221QS's VA panel is better for dark rooms, and its 32 inch screen provides much more screen real estate for multitasking.
