If budget is a primary concern and you're looking for a curved monitor with better contrast for more immersive gaming and media, the Dell S3422DWG could be a solid pick. However, if color accuracy is crucial, for example for photo editing, and you prefer a wider color gamut and better overall image clarity with less ghosting, the LG 34GN850B is preferable, though it comes at a higher cost. The LG also has a slightly higher refresh rate, which can enhance smoothness in games. Keep in mind that the Dell's contrast will offer deeper blacks, which the LG may fall short on due to its lower contrast ratio. Give Feedback

Whitson Gordon | August 2021
"The Dell S3422DWG is, overall, a great monitor that delivers on most of its promises, providing a sharp ultrawide experience with smooth motion. It is, however, not as great of a value proposition, costing a bit too much compared to similar competitors."

"Mid-range 3440 x 1440 144Hz VA monitors are ~$500 to $600 these days. You are getting a much better product for the higher price of the LG, with faster response times and better colors (outside of the contrast ratio), but this is definitely a monitor that is reserved for those that want the best of the best and are willing to pay for it."
