If you are focused on competitive gaming, the Dell Alienware with its higher refresh rate and shorter response time would be an excellent choice. However, for a more immersive media consumption or a wider field of view in productivity tasks, the larger, wider screen of the LG might be preferable. Both have similar capabilities for tasks like digital photo editing, but neither is ideal for HDR gaming or professional HDR video editing. The Dell offers slightly better text clarity and image highlights, but if screen real estate is crucial for multitasking, LG's ultra-wide format could outweigh that advantage. Give Feedback

How the Dell Alienware AW2723DF (IPS) and the LG 34GN850B (IPS) compare to other monitors
"Put all the pieces together, the high quality IPS image quality, the punchy backlight, the good response and the buttery smooth 280Hz refresh and you have a pretty outstanding gaming panel that's also decent for general computing duties thanks to the 1440p resolution."
"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."
