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
35 ms ... rise ↗ and fall ↘ combined↗ 8 ms rise
↘ 27 ms fall
The screen shows slow response rates in our tests and will be unsatisfactory for gamers.
In comparison, all tested devices range from 0.1 (minimum) to 240 (maximum) ms. » 92 % 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
36 ms ... rise ↗ and fall ↘ combined↗ 19 ms rise
↘ 17 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. » 46 % of all devices are better.
This means that the measured response time is similar to 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 ≤ 20 % brightness setting

The display backlight flickers at 1000 Hz (worst case, e.g., utilizing PWM) Flickering detected at a brightness setting of 20 % 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 8743 (minimum: 5 - maximum: 343500) Hz was measured.

O Dell XPS 12 9250 é um fino conversível de 12,5-polegadas. O processador Intel Core m7 6Y75 instalado, tem suficiente poder para tarefas rotineiras, e o seu TDP permite o resfriamento passivo. O SSD impressiona com taxas de leitura altas e garante um sistema rápido. A tela de alta resolução de 12,5-polegadas com 3840x2160 pixels convence com alto contraste, boa cobertura do espaço de cores e boa estabilidade dos ângulos de visão. Também é muito responsivo como dispositivo de entrada e implementa comandos instantaneamente. O dock de teclado combina bem com o visual do tablet e agrada o usuário com um teclado silencioso e um touchpad muito preciso.

A primeira vista, um elegante conversível que se torna ainda mais interessante quando da uma olhada mais de perto nas especificações. No entanto, a questão de se a Dell talvez colocou o preço muito alto, permanece.

Apesar de tudo isso, ainda há motivos de crítica. O ângulo de inclinação não pode ser ajustado para a posição de assentamento, o qual não permite uma posição de trabalho ergonômica no escritório. Embora o modelo de teste esteja equipado com o processador mais poderosos da linha Core m da Intel, o desempenho não pode ser completamente usado plenamente. Por isso, o Microsoft Surface Pro 4 com um Core m3, por exemplo, algumas vezes é muito mais veloz. Também esperávamos uma duração ais longa da bateria. O desempenho da bateria deveria ser um pouco melhor em um tablet que também é anunciado para o setor empresarial.

Com ou sem recomendação de compra - quem estiver pensando em comprar este tipo de aparelho agora saberá que desvantagens devem se esperar e/ou que aspectos convincentes o aparelho possui. A Dell demanda exorbitantes 1.799 Euros (~$ 2051) pela configuração de teste. Isso definitivamente não e uma barganha, mas é um dos poucos aparelhos com um painel 4K de 12,5-polegadas - se esse for um fator decisivo. Talvez uma configuração com uma CPU mais fraca entraria em questão, dado que o desempenho pleno do processador Core m7 instalado, não pode ser utilizado de qualquer forma.
