27" AOpen 27MX1
vs
27" HP 27f

For the average response rate, the AOpen 27MX1 scores 1.5 ms, which is faster than the HP 27f . The AOpen 27MX1 has a VESA mount while the HP 27f does not. The minimum response rate of AOpen 27MX1 is 1 ms, which is 133 % faster than the HP 27f . AOpen 27MX1 has lower total input lag than HP 27f .

27" AOpen 27MX1

With the AMD FreeSync support, this monitor is compatible with both AMD and NVIDIA graphics cards. For the average response rate, the AOpen 27MX1 scores 1.5 ms, which ensures effective synchronization with the high refresh rate. The minimum response rate of AOpen 27MX1 is 1 ms, which is eliminates ghosting effects. AOpen 27MX1 has a total input lag of 12 ms, which is excellent among the competition. The monitor has a VESA mount. The AOpen 27MX1 is a relatively new monitor. The brightness of AOpen 27MX1 is lower than other monitors. The AOpen 27MX1 has a maximum refresh rate of 75 Hz and this may be too low for the extremely fast frame rates in competitive games. For graphics color quality, the AOpen 27MX1 has an average color depth of 6 -bit, resulting in dithered gradients and more slightly less accurate colors. The AOpen 27MX1 has no Display Port and which is essential for NVIDIA cards to work with AMD FreeSync. 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. Graphically demanding games may cause frame drops outside the adative refresh rate of 48 Hz. In terms of pixel density, the AOpen 27MX1 has an low density of 81 pixels-per-inch, resulting in pixelated text and picture quality.

27" HP 27f

The monitor panel has good viewing angles and offers better contrast and colors than TN panels. The HP 27f is a relatively new monitor. With the AMD FreeSync support, this monitor is compatible with both AMD and NVIDIA graphics cards. The HP 27f has a maximum refresh rate of 75 Hz and this may be too low for the extremely fast frame rates in competitive games. The HP 27f has no Display Port and which is essential for NVIDIA cards to work with AMD FreeSync. The brightness of HP 27f is lower than other monitors. Graphically demanding games may cause frame drops outside the adative refresh rate of 48 Hz. The monitor does not have a VESA mount. For graphics color quality, the HP 27f has an average color depth of 6 -bit, resulting in dithered gradients and more slightly less accurate colors. In terms of pixel density, the HP 27f has an low density of 81 pixels-per-inch, resulting in pixelated text and picture quality. For the average response rate, the HP 27f scores 14 ms, which can cause motion blurring due to ineffective synchronization with the high refresh rate. The minimum response rate of HP 27f is 5 ms, which is can cause ghosting effects. The monitor has an unimpressive contrast ratio of 1000 : 1. HP 27f has a total input lag of 29 ms, which is bad among the competition.
