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
15 ms ... rise ↗ and fall ↘ combined↗ 11 ms rise
↘ 4 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 0.8 (minimum) to 240 (maximum) ms. » 12 % of all devices are better.
This means that the measured response time is better than the average of all tested devices (25.7 ms).
       Response Time 50% Grey to 80% Grey
41 ms ... rise ↗ and fall ↘ combined↗ 24 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 0.9 (minimum) to 636 (maximum) ms. » 49 % of all devices are better.
This means that the measured response time is similar to the average of all tested devices (41.1 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 26000 Hz ≤ 20 % brightness setting

The display backlight flickers at 26000 Hz (Likely 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 26000 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 8681 (minimum: 43 - maximum: 142900) Hz was measured.

O Vostro 15 5568 ainda é um portátil empresarial econômico. O desempenho oferecido é apropriado para o baixo preço. O baixo desempenho de WLAN e o teclado ruim, em particular, podem desencorajar os clientes interessados. Se os recursos de segurança minimalistas devem ser tomados em consideração para a decisão de compra é algo que os potenciais compradores devem decidir por si mesmos.

Com o Vostro 15 5568, a Dell oferece um portátil empresarial visualmente agradável. A WLAN e os recursos de segurança apresentam algumas falhas.

Para os clientes interessados que procuram um portátil empresarial barato, o Vostro 15 5568 certamente ainda é adequado. O dispositivo pode rodar aplicativos de escritório padrão (apresentações, análise de planilhas e e-mails) sem problemas. No entanto, a tela ruim deve ser levada em consideração, especialmente para aplicativos 3D que exigem uma placa gráfica dedicada. Se os ângulos de visão oferecidos e a cobertura do espaço de cores forem suficientes, este portátil é uma opção de compra válida.
