If you're a competitive gamer or serious about media consumption, particularly HDR content, the Dell Alienware AW3423DWF with its QD-OLED panel offers excellent image clarity, contrast, and color performance, ideal for deep blacks and vibrant gaming visuals. However, it comes at a premium price. The LG 34GN850B, while more affordable, may not match the Alienware's superior display qualities, particularly in HDR gaming. It could be a better fit for general productivity and casual gaming where the high cost of leading-edge display tech is less justified. Give Feedback

"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."

"Mid-range 3440 x 1440 144Hz VA monitors are ~$500 to $600 these days. You are getting a much better product for the higher price of the LG, with faster response times and better colors (outside of the contrast ratio), but this is definitely a monitor that is reserved for those that want the best of the best and are willing to pay for it."
