If you prioritize competitive gaming, the Dell Alienware monitor offers a superior gaming experience due to its higher refresh rate, which means smoother visuals and less motion blur. However, its lower SDR and HDR peak brightness could make it less suitable for brightly lit rooms compared to the Acer monitor. The Acer has a higher peak brightness, making it better for HDR gaming and media consumption in various lighting conditions. Both monitors are excellent for digital photo editing due to their high color accuracy. Choose Acer if you favor brightness and media, but prefer Dell for the edge in competitive gaming at a somewhat lower price. Give Feedback
