27" LG 27MK400H gaming monitor performance benchmarks: response, input and full specs review

The minimum response rate of LG 27MK400H is 2 ms, which is eliminates ghosting effects. For the average response rate, the LG 27MK400H scores 3 ms, which ensures effective synchronization with the high refresh rate. For graphics color quality, the LG 27MK400H has an excellent color depth of 8 -bit, resulting in smoother gradients and more accurate colors. With the AMD FreeSync support, this monitor is compatible with both AMD and NVIDIA graphics cards. The monitor has a VESA mount. The LG 27MK400H is a relatively new monitor. LG 27MK400H has a total input lag of 18 ms, which is bad among the competition. Graphically demanding games may cause frame drops outside the adative refresh rate of 56 Hz. The brightness of LG 27MK400H is lower than other monitors. The LG 27MK400H 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. The monitor has an unimpressive contrast ratio of 1000 : 1. The LG 27MK400H has a maximum refresh rate of 75 Hz and this may be too low for the extremely fast frame rates in competitive games. In terms of pixel density, the LG 27MK400H has an low density of 81 pixels-per-inch, resulting in pixelated text and picture quality.
