27" HP Omen 27

The monitor has a VESA mount. In terms of pixel density, the HP Omen 27 has an excellent density of 109 pixels-per-inch, resulting in sharper text and picture quality. To compensate for graphically demanding games, the HP Omen 27 has a very good low end adaptive refresh rate of 24 Hz that can adapt to more lower frame rate drops. For the average response rate, the HP Omen 27 scores 4 ms, which ensures effective synchronization with the high refresh rate. The HP Omen 27 has the Display Port and this is essential for NVIDIA cards to work with AMD FreeSync. HP Omen 27 has a total input lag of 11.5 ms, which is excellent among the competition. For the extremely fast frame rates, the HP Omen 27 has a maximum refresh rate of 165 Hz that allows smoother gameplay. The minimum response rate of HP Omen 27 is 1 ms, which is eliminates ghosting effects. The HP Omen 27 is a relatively new monitor. Without the AMD FreeSync support, this monitor is not compatible with AMD graphics cards. The brightness of HP Omen 27 is lower than other monitors. For graphics color quality, the HP Omen 27 has an average color depth of 6 -bit, resulting in dithered gradients and more slightly less accurate colors. 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.

27" Iiyama ProLite XUB2792QSU

In terms of pixel density, the Iiyama ProLite XUB2792QSU has an excellent density of 109 pixels-per-inch, resulting in sharper text and picture quality. 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 Iiyama ProLite XUB2792QSU has the Display Port and this is essential for NVIDIA cards to work with AMD FreeSync. For graphics color quality, the Iiyama ProLite XUB2792QSU has an excellent color depth of 8 -bit, resulting in smoother gradients and more accurate colors. Graphically demanding games may cause frame drops outside the adative refresh rate of 55 Hz. The brightness of Iiyama ProLite XUB2792QSU is lower than other monitors. The minimum response rate of Iiyama ProLite XUB2792QSU is 5 ms, which is can cause ghosting effects. The Iiyama ProLite XUB2792QSU has a maximum refresh rate of 75 Hz and this may be too low for the extremely fast frame rates in competitive games. Iiyama ProLite XUB2792QSU has a total input lag of 18.5 ms, which is bad among the competition. For the average response rate, the Iiyama ProLite XUB2792QSU scores 9 ms, which can cause motion blurring due to ineffective synchronization with the high refresh rate. It is worth noting that the Iiyama ProLite XUB2792QSU is a relatively old monitor. The monitor has an unimpressive contrast ratio of 1000 : 1.
