Test: Dell Latitude 7400 - Inte ens toppskiktet är fritt från svagheter (Sammanfattning)

Name: Dell Latitude 7400-8N6DH
Brand: Dell

Toppskiktsmodell för kontoret.

Dells kontorslaptop på 14 tum kan skryta med lång batteritid, ett utmärkt tangentbord och en snabb NVMe SSD-enhet. Den matta IPS-skärm kunde dock haft högre ljusstyrka. Dessutom avger fläkten ett högfrekvent visslande ljud.

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
37.6 ms ... rise ↗ and fall ↘ combined	↗ 21.2 ms rise
37.6 ms ... rise ↗ and fall ↘ combined	↘ 16.4 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. » 95 % 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
62 ms ... rise ↗ and fall ↘ combined	↗ 29.6 ms rise
62 ms ... rise ↗ and fall ↘ combined	↘ 32.4 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. » 96 % of all devices are better. This means that the measured response time is worse than the average of all tested devices (32.9 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 not detected

In comparison: 53 % of all tested devices do not use PWM to dim the display. If PWM was detected, an average of 8746 (minimum: 5 - maximum: 343500) Hz was measured.

Recension av Dell Latitude 7400 (8N6DH). Recensionsex från:

Läs den fullständiga versionen av den här recensionen på engelska här.

Dell Latitude 7400 är en aning kompaktare och lättare än sin föregångare. Enheten är ännu mer tilltalande tack vare den tunt infattade skärmen. Innanmätet stämmer överens med de senaste trenderna. En fyrkärnig Whiskey Lake-processor levererar tillräckligt med datorkraft för kontors- och internetapplikationer. Men den fulla potentialen kan bara nås i AC-läge. Vid batteridrift använder processorn knappt turbo överhuvudtaget och eventuellt gör den det inte alls. Det är priset du får betala för bra batteritid.

Med Latitude 7400 levererar Dell en toppskiktslaptop för kontoret som dock inte är utan svagheter.

En snabb NVMe SSD-enhet säkrar ett kvickt system. Det är möjligt att byta SSD-enheten, men då får man öppna höljet. En höjdpunkt med datorn är i vårt tycke tangentbordet. Det är ett av de bästa tangentborden vi sett. Två nivåer av tangentbelysning ingår förstås.

Den matta IPS-skärmen får poäng för stabila betraktningsvinklar, bra kontrast, skaplig färgåtergivning direkt vid leverans och bra färgrymdstäckning. Ljusstyrkan är okej men borde varit bättre på en enhet i den här priskategorin. På grund av det går det inte riktigt att använda datorn utomhus.

Thunderbolt 3-porten gör det möjligt att ansluta dockningslösningar och/eller en kraftfull extern GPU. Porten har förstås stöd för både Power Delivery 3.0 och DisplayPort genom USB-C (vilket kräver en separat adapter). Tyvärr avger fläkten ett visslande ljud.
