If high performance in competitive gaming and a wide color gamut for HDR gaming and media consumption are top priorities, the Acer Predator X45 is an excellent choice, but it comes at a high cost. It will also excel in digital photo editing due to its superior color accuracy. However, for a more budget-friendly option that still offers good performance for casual and competitive gaming as well as productivity and media consumption, the Dell S2722DGM could be more suitable. Keep in mind, though, it won't match the Acer's performance for tasks requiring high color fidelity such as professional photo editing. Give Feedback

Christian Eberle | February 2022
"Though it leaves out HDR and extended color, the Dell S2722DGM delivers superb gaming performance for less than $300. With Adaptive-Sync, 165 Hz, a solid overdrive and usable blur reduction, it rocks full-motion gaming without breaking the bank."
