If you prioritize a premium gaming experience with excellent color depth, contrast, and wide color gamut coverage, and don’t mind investing more, the Corsair 45WQHD240 with its OLED panel is a strong choice, especially for HDR gaming and media consumption. Its ultra-wide aspect ratio enhances immersive gaming and multitasking, but the text and image clarity are not as sharp as other monitors. In contrast, the Dell Alienware AW2723DF offers very good gaming performance and image clarity at a lower price, making it a better value for everyday productivity and gaming, though it falls short in HDR performance and the premium contrast experience found in OLED displays.

Jeremy Laird | March 2023
"Put all the pieces together, the high quality IPS image quality, the punchy backlight, the good response and the buttery smooth 280Hz refresh and you have a pretty outstanding gaming panel that's also decent for general computing duties thanks to the 1440p resolution."
