Our Verdict
Dell S2721HGF
HP X24ih
The HP X24ih and the Dell S2721DGF are two great gaming monitors with different panel types. The HP has an IPS panel with wider viewing angles, and it also has a much quicker response time that results in smoother motion. However, the VA panel on the Dell provides a better contrast ratio, making it a better choice for dark room gaming. Other than that, they each have FreeSync support and low input lag for gaming.
