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
24 ms ... rise ↗ and fall ↘ combined↗ 6.8 ms rise
↘ 17.2 ms fall
The screen shows good response rates in our tests, but may be too slow for competitive gamers.
In comparison, all tested devices range from 0.1 (minimum) to 240 (maximum) ms. » 50 % of all devices are better.
This means that the measured response time is worse than the average of all tested devices (21 ms).
       Response Time 50% Grey to 80% Grey
45.2 ms ... rise ↗ and fall ↘ combined↗ 22.4 ms rise
↘ 22.8 ms fall
The screen shows slow response rates in our tests and will be unsatisfactory for gamers.
In comparison, all tested devices range from 0.165 (minimum) to 636 (maximum) ms. » 75 % of all devices are better.
This means that the measured response time is worse than the average of all tested devices (32.9 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 detected 1000 Hz ≤ 90 % brightness setting

The display backlight flickers at 1000 Hz (worst case, e.g., utilizing PWM) Flickering detected at a brightness setting of 90 % and below. There should be no flickering or PWM above this brightness setting.

The frequency of 1000 Hz is quite high, so most users sensitive to PWM should not notice any flickering.

In comparison: 53 % of all tested devices do not use PWM to dim the display. If PWM was detected, an average of 8774 (minimum: 5 - maximum: 343500) Hz was measured.

In review: Dell Latitude 12 E5270. Test model courtesy of Dell Germany.

O Dell Latitude 12 E5270 é um portátil empresarial com muitos recursos de segurança que frequentemente podem ser decisivos para a compra. Os novos processadores Skylake conseguiram aumentar um pouco o desempenho em comparação com o predecessor. A duração da bateria também melhorou graças a uma bateria um pouco mais potente. O preço de 1295 Euros (~$1449) para o nosso modelo de teste ultrapassa claramente o limite de 1000-Euros (~$1119). Por isso, o preço definitivamente não é uma barganha para um aparelho de 12,5-polegadas. No entanto, o portátil apresenta uma construção impecável e rígida. Além disso, tudo é feito para a longevidade  e a seleção de recursos de segurança é vasto. As interfaces se posicionam de forma sensata e é possível expandi-las com uma estação docking. Os compradores começaram a apreciar estes pequenos detalhes e que também estejam preparados para investir dinheiro por eles. Apenas o nome da linha Latitude significa qualidade e boa construção.

No entanto, a primeira impressão muito boa é claramente marcada pela pobre qualidade do painel.

Temos que mencionar alguns pontos de crítica aqui. A tela, que é totalmente obsoleta, não é apta para um portátil empresarial desta faixa de preços, embora a fabricante ofereça melhores alternativas por um cargo. O baixo brilho da tela torna difícil trabalhar em ambientes iluminados. Desejaríamos um SSD veloz como armazenamento do sistema para um portátil empresarial. Os preços dos SSDs caíram drasticamente recentemente, diminuindo cada vez mais a diferença de preços com os discos rígidos convencionais.

Também gostamos da carcaça básica, fina e rígida. O desempenho de cômputo do Intel Core i5-6300U é definitivamente suficiente para tarefas rotineiras. Também podemos confirmar os bons dispositivos de entrada, como o touchpad e teclado. Este último também possui uma luz de fundo com dois níveis de brilho.
