25" Dell Alienware AW2521H gaming monitor performance benchmarks: response, input and full specs review

In terms of pixel density, the Dell AW2521H has an excellent density of 91 pixels-per-inch, resulting in sharper text and picture quality. For graphics color quality, the Dell AW2521H has an excellent color depth of 10 -bit, resulting in smoother gradients and more accurate colors. The monitor panel has good viewing angles and offers better contrast and colors than TN panels. The Dell AW2521H has the Display Port and this is essential for NVIDIA cards to work with AMD FreeSync. For the extremely fast frame rates, the Dell AW2521H has a maximum refresh rate of 360 Hz that allows smoother gameplay. The brightness of Dell AW2521H is significantly better than other monitors. To compensate for graphically demanding games, the Dell AW2521H has a very good low end adaptive refresh rate of 20 Hz that can adapt to more lower frame rate drops. For the average response rate, the Dell AW2521H scores 6.9 ms, which ensures effective synchronization with the high refresh rate. The Dell AW2521H is a relatively new monitor. The monitor has a VESA mount. The monitor has an unimpressive contrast ratio of 1336 : 1. Dell AW2521H has a total input lag of 15.4 ms, which is bad among the competition. Without the AMD FreeSync support, this monitor is not compatible with AMD graphics cards. The minimum response rate of Dell AW2521H is 3.1 ms, which is can cause ghosting effects.
