If you're a competitive gamer looking for fast response times and a high refresh rate, the Acer XB323U-GX is an excellent option, but if you prioritize stunning visuals, the deeper blacks, and higher contrast of the Dell Alienware AW3423DWF's OLED panel will be more appealing for both gaming and watching movies. The Dell monitor also offers a wider field of view with its ultrawide screen, which can be immersive for games and productive for multitasking. However, the Acer might be more suited for print photo editing, given its higher sRGB coverage and color accuracy. Choose the Dell for an immersive experience at a lower price, or the Acer if you need a monitor that excels in fast-paced gaming and precise color work. 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."
