If you're a competitive gamer or enjoy immersive gaming and media with vibrant colors, the Dell Alienware monitor provides a high refresh rate, deep contrasts, and responsiveness, all of which are excellent for gaming and HDR content. However, it's not the best for productivity due to its lower resolution and screen aspect. On the other hand, the LG UltraFine offers a much higher resolution which is great for productivity tasks and digital photo editing, offering crisp text and image clarity. Its higher price reflects its suitability for professional creative work, but it's not as suitable for gaming due to a lower refresh rate and lack of certain gaming features. Choose the Dell for a gaming and media-focused experience at a lower cost, or the LG for top-tier professional use and superior text clarity at a higher price point. 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."
