If you prioritize high refresh rates and competitive gaming, the Corsair Xeneon 27QHD240 is an excellent choice with its fast response time and very high refresh options, but its smaller screen and aspect ratio might limit productivity and media immersion. On the other hand, the Dell Alienware AW3423DWF offers a wider, curved display which can enhance immersion for media and provide more screen real estate for productivity, but it has a lower refresh limit. Both monitors are suitable for color-critical work and HDR gaming, although the Corsair's peak brightness is higher, which could enhance HDR content slightly more. For a balance of media consumption and productivity with competitive gaming as a secondary consideration, the Dell might be the better choice. If gaming performance is paramount, especially in fast-paced scenarios, you might favor the Corsair. Give Feedback

PC Gamer

Jeremy Laird | May 2023
"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."
