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
32 ms ... rise ↗ and fall ↘ combined↗ 18 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. » 81 % of all devices are better.
This means that the measured response time is worse than the average of all tested devices (25.2 ms).
       Response Time 50% Grey to 80% Grey
42 ms ... rise ↗ and fall ↘ combined↗ 22 ms rise
↘ 20 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. » 54 % of all devices are better.
This means that the measured response time is similar to the average of all tested devices (40.2 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 208 Hz ≤ 90 % brightness setting

The display backlight flickers at 208 Hz (Likely 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 208 Hz is relatively low, so sensitive users will likely notice flickering and experience eyestrain at the stated brightness setting and below.

In comparison: 51 % of all tested devices do not use PWM to dim the display. If PWM was detected, an average of 9439 (minimum: 43 - maximum: 142900) Hz was measured.

O Dell Latitude 3390 é um conversível empresarial de 13,3 polegadas com preços razoáveis. Nossa unidade de teste vem com um processador Intel Core i5-8250U, 8 GB de RAM e um SSD de 256 GB, o que o torna bem equipado para seu preço de de 999 Euros (~$ 1.130). Em suma, o Latitude 3390 na configuração que testamos é comparativamente barato para um dispositivo de negócios e é uma alternativa decente para portáteis de consumo e para compradores privados também.

Infelizmente, o dispositivo não possui recursos empresariais importantes, como conectividade LTE opcional e recursos de segurança, como um sensor de digitais. Portanto, o Latitude 3390 provavelmente será uma opção pouco atraente para os profissionais.

O Core i5-8250U quad-core é poderoso o suficiente para as tarefas mais exigentes, assim como os 8 GB de RAM. No entanto, eles não são preparados para o futuro e dão a impressão de que a Dell trouxe o Latitude 3390 ao mercado com um ano de atraso. O design também é parte dessa visão. O design simples parecerá elegante para algumas pessoas, mas os marcos de tela ampla parecem desatualizados. A Dell poderia ter facilmente equipado o Latitude 3390 com um painel de 14 polegadas dentro do mesmo chassi.

Enquanto estamos no assunto, a tela é uma das grandes decepções do Latitude 3390. É simplesmente muito escura, tornando muito desconfortáveis as tarefas em exteriores Da mesma forma, em nossa opinião, a cobertura de espaço de cores é muito baixa para um dispositivo de negócios.

O Dell Latitude 3390 deixa uma impressão ambígua. Não tem um ponto de venda exclusivo e não atende às expectativas do que um conversível empresarial deveria ser.

No entanto, nem tudo são más notícias. A Dell construiu o Latitude 3390 com fibra de carbono reciclada, o que torna a nossa unidade de teste mais robusta. Ao mesmo tempo, mantém o peso total abaixo dos 1,6 kg. A tela táctil, o trackpad e o teclado também são decentes, embora o último não esteja no mesmo nível que os concorrentes do ThinkPad. O Latitude 3390 também é extremamente eficiente em termos de energia e tem alto-falantes amplos, mas é provável que eles sejam esquecidos quando as pessoas experimentem sua tela.

The Dell Latitude 3390 is a reasonably priced 13.3-inch business convertible. Our review unit comes with an Intel Core i5-8250U processor, 8 GB of RAM and a 256 GB SSD, which makes it well equipped for its 999-Euro (~$1,130) retail price. In short, the Latitude 3390 in the configuration that we tested is comparatively cheap for a business device and is a decent alternative to consumer-grade laptops for private buyers too.

Unfortunately, the device lacks important business features like optional LTE connectivity and security features like a fingerprint sensor. Hence, the Latitude 3390 will probably prove an unattractive option for professionals.

The quad-core Core i5-8250U is powerful enough for most demanding tasks though, as is the 8 GB of RAM. However, they are not future-proofed and give the impression that Dell has brought the Latitude 3390 to market a year late. The design compounds this view too. The simple design will look elegant to some people, but the wide display bezels look outdated. Dell could have easily equipped the Latitude 3390 with a 14-inch panel within the same chassis.

While we are on the subject, the display is one of the big let-downs of the Latitude 3390. It is simply too dark, making outdoor use a chore. Likewise, the colour-space coverage is too low for a business device in our opinion.

The Dell Latitude 3390 leaves an ambiguous impression. It has no unique selling point and does not meet expectations of what a business convertible should be.

It is not all bad news though. Dell has built the Latitude 3390 with recycled carbon fibre, which makes our review unit feel sturdy. At the same time, it keeps the overall weight below 1.6 kg. The touchscreen, trackpad and keyboard are decent too, although the latter is not in the same league as its ThinkPad competitors. The Latitude 3390 is impressively energy-efficient too and has full-bodied speakers, but these are likely to be forgotten when people experience its display.
