Display Response Times

ℹ

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
27 ms ... rise ↗ and fall ↘ combined	↘ 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 0.1 (minimum) to 240 (maximum) ms. » 63 % of all devices are better. This means that the measured response time is worse than the average of all tested devices (21.5 ms).
↔ Response Time 50% Grey to 80% Grey
38 ms ... rise ↗ and fall ↘ combined	↗ 19 ms rise
38 ms ... rise ↗ and fall ↘ combined	↘ 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 0.2 (minimum) to 636 (maximum) ms. » 49 % of all devices are better. This means that the measured response time is worse than the average of all tested devices (33.7 ms).

Screen Flickering / PWM (Pulse-Width Modulation)

ℹ

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: 53 % of all tested devices do not use PWM to dim the display. If PWM was detected, an average of 17903 (minimum: 5 - maximum: 3846000) Hz was measured.

The Acer Chromebook 14, provided by notebooksbilliger.de

"O Chromebook para o trabalho." É assim que a Acer gosta de ver seu novo Chromebook: um dispositivo de escritório para o trabalho diário. Já a primeira vista mostra que o Chromebook cresceu. Em vez de cores lúdicas, é construído com um visual brilhante de acabamento de piano. É lamentável que a superfície seja tão suscetível às impressões digitais. No entanto, para um dispositivo de trabalho, a adequação dos dispositivos de entrada é mais importante. O teclado em particular é adequado inclusive para dias mais longos no escritório. Para ser um dispositivo empresarial real, faltam mais recursos de segurança.

A tela IPS mate é muito sólida em geral. As cores e a escala de cinzas são bem reproduzidas. Infelizmente, falta um pouco de brilho à tela. Fontes de luz direta no escritório ou no exterior podem restringir a operação ou preveni-la completamente.

O equipamento de hardware em particular recebeu nossa atenção. No entanto, não pode aproveitar todo o seu potencial e até mesmo fica atrás dos processadores mais fracos da Intel Core m5 nos benchmarks. Ainda assim, o sistema funciona muito fluentemente e mais rápido do que outros Chromebooks.

O candidato da Acer ganha pontos com seus bons valores de emissão e uma duração de bateria de 9 horas.

O Acer Chromebook 14 para Trabalho é exatamente se supõe que deve ser: um portátil de escritório para o trabalho diário no escritório com suficiente estamina.

Quem quiser mudar completamente para um Chromebook como seu dispositivo principal também deve dar uma olhada no HP Chromebook 13 G1. E o Chromebook Lenovo ThinkPad 13 oferece ainda mais desempenho.
