If you have a high budget and prioritize a top-notch gaming experience, including competitive gaming with minimal ghosting and superior contrast, the Corsair Xeneon W-OLED would be the better option. However, if you're looking to save money and need a wider screen for multitasking and productivity, with a decent gaming experience, the LG IPS monitor could be more suitable. The Corsair also excels in HDR content, making it great for HDR gaming and media. On the other hand, the LG's larger screen and aspect ratio might be more immersive for media consumption, despite its lesser suitability for HDR. Choose the Corsair for high-end gaming and HDR media; choose the LG for work productivity and cost savings. 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."
