If you're a competitive gamer valuing fast response times and high refresh rates, the AOC AG276QZD is a strong option. For immersive gaming and media consumption with vibrant colors and wide viewing angles, the Dell Alienware AW3423DWF's larger, curved screen and glossy finish may appeal to you. While both have excellent color depth and are suitable for HDR gaming, the AOC excels in competitive gaming due to its very quick response. On the other hand, the Dell's ultra-wide aspect ratio and better color gamut coverage make it more suited for productivity and enjoying movies or video content. 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."
