Our Verdict

Acer G257HU Smidpx

HP 27Q

The HP 27Q is somewhat better than the Acer G257HU Smidpx. The HP 27Q has a better refresh rate that leaves a smaller blur trail in fast-moving content and has more screen area as it is a 27" monitor. The Acer G257HU, on the other hand, has a better input lag which makes it more responsive to your inputs and can be great for many usages.
