Display Response Times

Display response times show how fast the screen is able to change from one color to the next. Slow response times can lead to afterimages and can cause moving objects to appear blurry (ghosting). Gamers of fast-paced 3D titles should pay special attention to fast response times.
       Response Time Black to White
27 ms ... rise ↗ and fall ↘ combined↗ 16 ms rise
↘ 11 ms fall
The screen shows relatively slow response rates in our tests and may be too slow for gamers.
In comparison, all tested devices range from 0.8 (minimum) to 240 (maximum) ms. » 52 % of all devices are better.
This means that the measured response time is similar to the average of all tested devices (26.8 ms).
       Response Time 50% Grey to 80% Grey
38 ms ... rise ↗ and fall ↘ combined↗ 19 ms rise
↘ 19 ms fall
The screen shows slow response rates in our tests and will be unsatisfactory for gamers.
In comparison, all tested devices range from 0.9 (minimum) to 636 (maximum) ms. » 34 % of all devices are better.
This means that the measured response time is better than the average of all tested devices (43 ms).

Screen Flickering / PWM (Pulse-Width Modulation)

To dim the screen, some notebooks will simply cycle the backlight on and off in rapid succession - a method called Pulse Width Modulation (PWM) . This cycling frequency should ideally be undetectable to the human eye. If said frequency is too low, users with sensitive eyes may experience strain or headaches or even notice the flickering altogether.
Screen flickering / PWM not detected

In comparison: 58 % of all tested devices do not use PWM to dim the display. If PWM was detected, an average of 5885 (minimum: 43 - maximum: 142900) Hz was measured.

"Munkára tervezett Chromebook." Így reklámozza az Acer az új Chromebook-ját: irodai eszköz, mindennapi feladatokra. Az első pillantásra látszik, hogy a Chromebook felnőtt. Játékos színek helyett fényes "piano-finish" burkolatot kapott. Sajnos ez vonzza az ujjlenyomatokat. Egy munkaeszköz esetében azonban fontosabbak a beviteli eszközök. A billentyűzet hosszú munkanapok során is jól használható lesz. Ahhoz, hogy valódi üzleti gépnek tarthassuk, több biztonsági funkciónak kellene jelen lennie.

A matt IPS kijelző alapvetően jó. A színek és szürke árnyalatok jól néznek ki. Sajnos a fényereje nem a legjobb. Direkt megvilágítás, vagy kültéri világosság akadályozhatja (akár lehetetlenné is teheti) a használatát.

A hardver külön figyelmet érdemelt. Sajnos nem képes kiaknázni a benne rejlő potenciált, és benchmark eredményei elmaradnak még az Intel Core m5 processzorok mögött is. Így is gyorsabban és simábban fut azonban, mint több más Chromebook.

Az Acer versenyzője jó pontszámot ért el hő- és zajkibocsátásával, valamint 9 órás üzemidejével.

Az Acer Chromebook 14 for Work pont az, amire a neve alapján számíthatunk: irodai notebook, mindennapi irodai feladatokra.

Aki egy Chromebook-ot szeretne fő gépnek, az a HP Chromebook 13 G1-re vethet egy pillantást. A Lenovo ThinkPad 13 Chromebook pedig még nagyobb teljesítményt nyújt.
