If you prioritize a larger screen and top-tier gaming performance, consider the Asus PG32UCDM, especially for HDR gaming where it excels. The Dell Alienware AW3423DWF is less expensive, has a wider aspect ratio which is great for immersive gaming and multitasking, and also provides an excellent gaming experience. For productivity, the Alienware's ultra-wide screen may be advantageous, but for precise photo editing, the Asus offers slightly better color accuracy. Both are OLEDs, so you'll enjoy deep blacks and vibrant colors on either, but remember that an OLED's glossy finish can reflect more light, which may be distracting in bright rooms. Choose the Asus if budget is less of a concern and you want a traditional aspect ratio with slight advantages in color accuracy; go for the Dell if you want to save money and prefer an ultra-wide display for gaming and productivity.

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."
