If competitive gaming, especially with fast-paced games, is your priority and you're looking to save money, the BenQ XL2566K with its high refresh rate and very good response time would serve you well. However, if you're willing to invest in a premium experience that excels in both productivity and media consumption due to its larger, higher resolution screen and outstanding color quality, the Dell Alienware AW3423DWF should be your choice. The Dell also offers an immersive ultra-wide display and is suitable for more graphically-intense HDR gaming and media, but it does come at a higher cost. Give Feedback

"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."

"It may seem like a minor tweak, but the addition of a glossy anti-glare coating makes all the difference. It really lets the OLED panel rip. That this revised "F" model is also cheaper than the OG Alienware OLED and the similarly glossy Philips competition seals the deal. This is our new favourite among the OLED monitor massive."
