If you prioritize competitive gaming and are looking to save money, the BenQ XL2566K with its high refresh rate and quick response time could be a solid choice; however, its lower resolution and color performance may not be ideal for media consumption or editing tasks. In contrast, the LG 27EQ850 offers excellent color depth and clarity, making it a superb option for HDR gaming, media consumption, and photo editing, with the tradeoff of a higher price and lower refresh rate which isn't as optimal for competitive gaming.

Tech Radar
Nick Ross | August 2023
"It’s not for everyone in the same way that a top fuel dragster isn’t everyone’s perfect daily driver. The BenQ Zowie XL2566K succeeds in delivering the fastest, sharpest and smoothest display for pro FPS players and that’s all it wanted to do. Its other limitations and premium price tag mean it’s a bespoke tool for a niche market, rather than another general gaming monitor for those who like playing games."
