Ozone DSP27 has lower total input lag than Acer B277 . To compensate for graphically demanding games, the Acer B277 has better low end adaptive refresh rate of 55 Hz that can adapt to more lower frame rate drops.

27" Ozone DSP27

The Ozone DSP27 is a relatively new monitor. The monitor has a VESA mount. The Ozone DSP27 has the Display Port and this is essential for NVIDIA cards to work with AMD FreeSync. For the extremely fast frame rates, the Ozone DSP27 has a maximum refresh rate of 165 Hz that allows smoother gameplay. The minimum response rate of Ozone DSP27 is 1 ms, which is eliminates ghosting effects. For the average response rate, the Ozone DSP27 scores 1.5 ms, which ensures effective synchronization with the high refresh rate. With the AMD FreeSync support, this monitor is compatible with both AMD and NVIDIA graphics cards. Ozone DSP27 has a total input lag of 12 ms, which is excellent among the competition. Graphically demanding games may cause frame drops outside the adative refresh rate of 165 Hz. The brightness of Ozone DSP27 is lower than other monitors. 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. In terms of pixel density, the Ozone DSP27 has an low density of 81 pixels-per-inch, resulting in pixelated text and picture quality. The monitor has an unimpressive contrast ratio of 1000 : 1. For graphics color quality, the Ozone DSP27 has an average color depth of 6 -bit, resulting in dithered gradients and more slightly less accurate colors.

27" Acer B277

The Acer B277 is a relatively new monitor. The monitor panel has good viewing angles and offers better contrast and colors than TN panels. The monitor has a VESA mount. With the AMD FreeSync support, this monitor is compatible with both AMD and NVIDIA graphics cards. The Acer B277 has the Display Port and this is essential for NVIDIA cards to work with AMD FreeSync. In terms of pixel density, the Acer B277 has an low density of 81 pixels-per-inch, resulting in pixelated text and picture quality. Acer B277 has a total input lag of 19.5 ms, which is bad among the competition. The Acer B277 has a maximum refresh rate of 75 Hz and this may be too low for the extremely fast frame rates in competitive games. Graphically demanding games may cause frame drops outside the adative refresh rate of 55 Hz. The monitor has an unimpressive contrast ratio of 1000 : 1. For the average response rate, the Acer B277 scores 10 ms, which can cause motion blurring due to ineffective synchronization with the high refresh rate. For graphics color quality, the Acer B277 has an average color depth of 6 -bit, resulting in dithered gradients and more slightly less accurate colors. The brightness of Acer B277 is lower than other monitors. The minimum response rate of Acer B277 is 4 ms, which is can cause ghosting effects.
