24.5" Acer KG251QH gaming monitor performance benchmarks: response, input and full specs review

In terms of pixel density, the Acer KG251QH has an excellent density of 89 pixels-per-inch, resulting in sharper text and picture quality. For the extremely fast frame rates, the Acer KG251QH has a maximum refresh rate of 144 Hz that allows smoother gameplay. The Acer KG251QH is a relatively new monitor. For the average response rate, the Acer KG251QH scores 3 ms, which ensures effective synchronization with the high refresh rate. The brightness of Acer KG251QH is significantly better than other monitors. The monitor has a VESA mount. With the AMD FreeSync support, this monitor is compatible with both AMD and NVIDIA graphics cards. The minimum response rate of Acer KG251QH is 1 ms, which is eliminates ghosting effects. The Acer KG251QH has the Display Port and this is essential for NVIDIA cards to work with AMD FreeSync. For graphics color quality, the Acer KG251QH has an average color depth of 6 -bit, resulting in dithered gradients and more slightly less accurate colors. Acer KG251QH has a total input lag of 18 ms, which is bad among the competition. The monitor uses a TN panel which suffers from color shifting when viewed from horizontal and vertical angles and has slightly washed colors compared to IPS and VA panels. Graphically demanding games may cause frame drops outside the adative refresh rate of 48 Hz. The monitor has an unimpressive contrast ratio of 1000 : 1.
