Our Verdict
LG 32UD99-W
Dell UltraSharp U2721DE
The LG 32UD99-W is much better than the Dell UltraSharp U2721DE for most people. The LG has a larger, higher-resolution screen, which is much better for multitasking, and it delivers sharper text. The LG also supports HDR and is a more versatile monitor thanks to a few dedicated gaming features. On the other hand, the Dell has much better reflection handling, making it a better choice for a bright office.
