If you prioritize a better gaming experience with higher refresh rate for fast-paced action and support for newer HDMI standards, the Asus VG28UQL1A is a strong choice; however, it's more expensive. The Dell S2721QS, while more affordable and offering slightly better color accuracy for tasks like photo editing, has a lower refresh rate limiting its suitability for competitive gaming. Both monitors provide sharp image quality for productivity and media consumption due to their 4K resolution, but the Asus might be more future-proof for gaming advancements. Give Feedback

Matthew Smith | March 2022
"The Asus TUF Gaming VG28UQL1A is, in many ways, a great 4K gaming monitor. It has a sharp, accurate image with good contrast and excellent motion clarity. Luminance uniformity is its only weakness. The monitor’s $799 MSRP is relatively affordable for a 4K HDMI 2.1 monitor, as well."

"The Dell S2721QS 4K monitor brings IPS-level colors and some handy features, like a versatile stand with height adjustments and picture-in-picture for connecting dual systems. But don’t get it for HDR."
