24.5" Acer KG251QD gaming monitor performance benchmarks: response, input and full specs review

The Acer KG251QD has the Display Port and this is essential for NVIDIA cards to work with AMD FreeSync. For the average response rate, the Acer KG251QD scores 3 ms, which ensures effective synchronization with the high refresh rate. In terms of pixel density, the Acer KG251QD has an excellent density of 89 pixels-per-inch, resulting in sharper text and picture quality. The brightness of Acer KG251QD is significantly better than other monitors. The Acer KG251QD is a relatively new monitor. With the AMD FreeSync support, this monitor is compatible with both AMD and NVIDIA graphics cards. The monitor has a VESA mount. For the extremely fast frame rates, the Acer KG251QD has a maximum refresh rate of 240 Hz that allows smoother gameplay. The minimum response rate of Acer KG251QD is 1 ms, which is eliminates ghosting effects. Acer KG251QD has a total input lag of 18 ms, which is bad among the competition. For graphics color quality, the Acer KG251QD has an average color depth of 6 -bit, resulting in dithered gradients and more slightly less accurate colors. 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. 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.
