If precise color work for digital photo editing is a priority, the Dell U2723QE significantly outperforms the LG 34GN850B, with better color coverage suitable for tasks like print photo editing. However, if you're looking for a monitor that enhances the gaming experience with a wider view and smoother motion, the LG is a superior fit, thanks to its wider aspect ratio and better handling of fast-moving images. The Dell provides sharper text for productivity tasks, whereas the LG's ultra-wide display may offer an immersive experience for media consumption but sacrifices some image clarity. Choose the Dell for work that requires color accuracy and the LG for a more engaging gaming and movie-watching experience. Give Feedback

TechSpot
Tim Schiesser | August 2020
"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."
