If you prioritize competitive gaming and have a higher budget, the Acer X27U with its OLED panel and superior total response time may greatly enhance your experience with deeper blacks and smoother motion. On the other hand, the Dell Alienware AW2723DF is more budget-friendly and still performs excellently for competitive gaming. However, it falls short for HDR gaming and media consumption compared to the Acer due to its less vibrant color reproduction and lower contrast. The Dell monitor is a good all-rounder for productivity and casual gaming but doesn't offer the same level of immersion for HDR content as the Acer does. 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."
