If you're looking for a high-quality monitor for competitive gaming and don't mind sacrificing a bit of productivity space, the Dell Alienware AW3423DWF strikes a balance between performance and price, offering a sharp and fast experience. On the other hand, if you're ready to invest more for a vast screen that excels in HDR gaming and media consumption, the Gigabyte CO49DQ's immersive size and superior brightness will be impressive. The Gigabyte, however, isn't as well-suited for tasks requiring image clarity or text quality, and it doesn't perform as well in fast-paced gaming due to potential ghosting issues. 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."
