Display Response Times
ℹ
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 | ||
|---|---|---|
| 42 ms ... rise ↗ and fall ↘ combined | ↗ 28 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 0.1 (minimum) to 240 (maximum) ms. » 98 % of all devices are better. This means that the measured response time is worse than the average of all tested devices (20.9 ms). | ||
| ↔ Response Time 50% Grey to 80% Grey | ||
| 44 ms ... rise ↗ and fall ↘ combined | ↗ 22 ms rise |  |
| ↘ 22 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. » 71 % of all devices are better. This means that the measured response time is worse than the average of all tested devices (32.8 ms). | ||
Screen Flickering / PWM (Pulse-Width Modulation)
ℹ
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 8710 (minimum: 5 - maximum: 343500) Hz was measured. | |||

Dell Latitude 3400 är en vardaglig kontorslaptop, särskilt när den kommer med en Intel Core i3-8145U processor. Men den är tillräckligt kraftfull för alla vanliga kontors- och internetrelaterade uppgifter. Den blir heller aldrig för varm eller för högljudd.
En snabb NVMe SSD-enhet säkrar dessutom att systemet känns smidigt och du kan byta ut den mot en enhet med större kapacitet om du skulle behöva. Men då får du montera isär enheten först.
Dell Latitude 3400 är en gedigen och billig kontorslaptop på 14 tum som inte kommer göra dig besviken när du arbetar.
Vi är också fans av tangentbordet och styrplattan, för att inte tala om batteritiden. På samma sätt har Latitude 3400 ett bra utbud av portar, inklusive USB Typ C med stöd för DisplayPort och USB PD. Men den mörka skärmen med låg kontrast gjorde oss besvikna och det är synd att den har en långsam kortläsare och bara 12 månaders standardgaranti. För att sammanfatta så är Dell Latitude 3400 en skaplig kontorslaptop som kommer att tilltala den som har en begränsad budget.
