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
30.4 ms ... rise ↗ and fall ↘ combined↗ 16.4 ms rise
↘ 14 ms fall
The screen shows slow response rates in our tests and will be unsatisfactory for gamers.
In comparison, all tested devices range from 0.8 (minimum) to 240 (maximum) ms. » 74 % of all devices are better.
This means that the measured response time is worse than the average of all tested devices (27.2 ms).
       Response Time 50% Grey to 80% Grey
40 ms ... rise ↗ and fall ↘ combined↗ 18.8 ms rise
↘ 21.2 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. » 40 % of all devices are better.
This means that the measured response time is similar to the average of all tested devices (44 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: 59 % of all tested devices do not use PWM to dim the display. If PWM was detected, an average of 2255 (minimum: 43 - maximum: 142900) Hz was measured.

A Dell destinou o Latitude 3189 principalmente para o setor educativo. A base para isto foi estabelecido com o seu design robusto. Recursos adicionais como a tela táctil, são bons e fornecem um valor adicional para o aparelho. Isto também faz com que o aparelho seja muito mais versátil. O Intel Pentium N4200, que pode contar com 4 GB de RAM DDR3, é o máximo que o fabricante tem a a oferecer com relação ao desempenho. Não recomendaríamos a configuração de CPU alternativa com o Intel Celeron N3350. Nossa unidade de teste, que não é a mais barata, com 799 Euros (~$857), funciona bastante bem, mas com um Intel Celeron N3350 (processador dual core), o desempenho seria significantemente pior.

O Dell Latitude 3189 é um aparelho muito robusto, que ajuda às crianças a aprender como lidar com a nova mídia. A unidade base estável pode lidar com muito e graças a sua ótima duração da bateria. Uma carga de bateria pode durar facilmente todo um dia na escola.

Temos algumas coisas a criticar sobre o Dell Latitude 3189: por exemplo, a porta USB Type-C ausente, que limitará o futuro do aparelho, e a tela muito refletiva, que pode ser irritante e dificulta o trabalho em ambientes claros. O aparelho de armazenamento tem vantagens e desvantagens. Uma vez que o sistema operacional e alguns programas são instalados, não resta muito da capacidade de armazenamento de 128 GB. No geral, podemos dizer que apesar de que não se saia tão bem em algumas áreas, em comparação com outras unidades de teste, o Dell Latitude 3189 faz um ótimo trabalho. O subjetivo desempenho do sistema foi definitivamente melhor que os resultados que mostraram os benchmarks.

Dell has aimed the Latitude 3189 mainly at the education sector. The basis for this has been established with its robust design. Additional features such as a touchscreen are good and add additional value to the device. This also makes the device a lot more versatile. The Intel Pentium N4200, which can rely on 4 GB of DDR3 RAM, is the maximum of what the manufacturer has to offer concerning performance. We would not recommend the alternative CPU configuration with the Intel Celeron N3350. Our test unit, which is not the cheapest at 799 Euros (~$857), runs quite well, but with an Intel Celeron N3350 (dual core processor), the performance would be significantly worse.

The Dell Latitude 3189 is a very robust device, which helps children learn how to handle the new media. The stable base unit can handle quite a lot and thanks to its great battery runtime, one battery charge easily lasts an entire day at school.

We have got a few things to criticize about the Dell Latitude 3189: for example the missing USB Type-C port, which would secure the device's future, and  the very reflective display, which can be irritating and make it difficult to work in light spaces. The storage device has advantages and disadvantages. Once the operating system and some programs are installed, not much is left of the 128 GB storage capacity. Overall, we can say that despite it not doing so well in some areas compared with the other test units, the Dell Latitude 3189 does a solid job. The subjective system performance was definitely better than the results the benchmarks showed.
