Our Verdict
Lenovo ThinkVision M14
Dell S2721HGF
The Dell S2721HGF is better overall than the Lenovo ThinkVision M14, mainly because they're for different uses. The Dell is a curved screen monitor designed with gamers in mind as it has a higher 144Hz refresh rate, VRR support, and much quicker response times. It's also a better choice for use in dark rooms because it has a much higher native contrast ratio. For well-lit rooms, the Dell gets brighter and has better reflection handling. On the other hand, the Lenovo is a portable monitor meant for on-the-go use. It has a smaller screen, resulting in a higher pixel density and better text clarity.
