If high-quality imagery for HDR gaming and media consumption is crucial for you and budget is less of a concern, the Acer Predator X45 with its OLED screen offers excellent contrast and color. However, keep in mind that it has lower text clarity, which could hinder productivity tasks. On the other hand, the Dell Alienware AW2723DF is more affordable, with good overall performance that makes it suitable for a balance of gaming, productivity, and media consumption. Its IPS panel provides better text clarity than the Acer but may not match the deep blacks and vibrant colors that the OLED panel offers. Both monitors have high refresh rates, but the Dell's faster response time and competitive gaming performance might appeal more if fast-paced gaming is a priority. Give Feedback

Jeremy Laird | March 2023
"Put all the pieces together, the high quality IPS image quality, the punchy backlight, the good response and the buttery smooth 280Hz refresh and you have a pretty outstanding gaming panel that's also decent for general computing duties thanks to the 1440p resolution."
