If you are focused on competitive gaming and want an immersive experience with a wide field of view, the Dell Alienware monitor's curved screen and ultra-wide aspect ratio are ideal; yet, its lower brightness may not pop as much in a well-lit room. If high-resolution media consumption and precise photo editing are your priorities, the MSI offers a higher pixel density and better HDR performance, which can be important for vibrant, detailed images, but it comes at a higher price. Both have OLED technology providing deep blacks and fast response times, but consider how much the resolution, screen size, and price align with your main usage. Give Feedback

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."
