24.5" Acer KG251QG gaming monitor performance benchmarks: response, input and full specs review

With the AMD FreeSync support, this monitor is compatible with both AMD and NVIDIA graphics cards. The minimum response rate of Acer KG251QG is 1 ms, which is eliminates ghosting effects. In terms of pixel density, the Acer KG251QG has an excellent density of 89 pixels-per-inch, resulting in sharper text and picture quality. For the average response rate, the Acer KG251QG scores 3 ms, which ensures effective synchronization with the high refresh rate. The monitor has a VESA mount. The Acer KG251QG is a relatively new monitor. The Acer KG251QG has no Display Port and which is essential for NVIDIA cards to work with AMD FreeSync. 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 55 Hz. For graphics color quality, the Acer KG251QG has an average color depth of 6 -bit, resulting in dithered gradients and more slightly less accurate colors. The monitor has an unimpressive contrast ratio of 1000 : 1. Acer KG251QG has a total input lag of 18 ms, which is bad among the competition. The brightness of Acer KG251QG is lower than other monitors. The Acer KG251QG has a maximum refresh rate of 75 Hz and this may be too low for the extremely fast frame rates in competitive games.
