vs
27" Dell Alienware AW2721D

The Dell AW2721D is newer than AOpen 27ML1U . The brightness of Dell AW2721D is better than AOpen 27ML1U by 31 %. To compensate for graphically demanding games, the Dell AW2721D has better low end adaptive refresh rate of 20 Hz that can adapt to more lower frame rate drops. Unlike Dell AW2721D , the AOpen 27ML1U has FreeSync support which makes it compatible with both AMD and NVIDIA graphics cards. Dell AW2721D has lower total input lag than AOpen 27ML1U . For the extremely fast frame rates, the Dell AW2721D has better maximum refresh rate of 240 Hz that allows smoother gameplay. The minimum response rate of Dell AW2721D is 2.6 ms, which is 63 % faster than the AOpen 27ML1U . For the average response rate, the Dell AW2721D scores 7.1 ms, which is faster than the AOpen 27ML1U . For graphics color quality, the Dell AW2721D has a better color depth of 10 -bit, resulting in smoother gradients and more accurate colors.

27" AOpen 27ML1U

For graphics color quality, the AOpen 27ML1U has an excellent color depth of 8 -bit, resulting in smoother gradients and more accurate colors. The monitor panel has good viewing angles and offers better contrast and colors than TN panels. The monitor has a VESA mount. The AOpen 27ML1U has the Display Port and this is essential for NVIDIA cards to work with AMD FreeSync. With the AMD FreeSync support, this monitor is compatible with both AMD and NVIDIA graphics cards. In terms of pixel density, the AOpen 27ML1U has an excellent density of 109 pixels-per-inch, resulting in sharper text and picture quality. The AOpen 27ML1U is a relatively new monitor. The monitor has an unimpressive contrast ratio of 1000 : 1. AOpen 27ML1U has a total input lag of 21.5 ms, which is bad among the competition. The brightness of AOpen 27ML1U is lower than other monitors. Graphically demanding games may cause frame drops outside the adative refresh rate of 75 Hz. For the average response rate, the AOpen 27ML1U scores 11 ms, which can cause motion blurring due to ineffective synchronization with the high refresh rate. The minimum response rate of AOpen 27ML1U is 5 ms, which is can cause ghosting effects. The AOpen 27ML1U has a maximum refresh rate of 75 Hz and this may be too low for the extremely fast frame rates in competitive games.
