Our Verdict
ASUS ROG Strix XG27AQ
Acer Nitro XV272U KVbmiiprzx
The Acer Nitro XV272U KVbmiiprzx and the ASUS ROG Strix XG27AQ are nearly identical in gaming performance. They both have a 170Hz refresh rate, exceptional response times, and low input lag. The Acer has better ergonomics, and it's better for HDR, as it's brighter and can display a wider color gamut.
