Test: Dell Latitude 7480 (7600U, FHD) (sammanfattning)

Bernie Pechlaner, 04/27/2017

Business as usual. Med nytt chassi, lägre vikt och kraftigt förbättrad batteritid bockar Latitude återigen av listan över rätt egenskaper för en företagslaptop. 14-tummaren 7480 är utrustad med den senaste hårdvaran, ett bra tangentbord och levererar bra prestanda. Tyvärr har den problem med "spoltjut".

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
31.2 ms ... rise ↗ and fall ↘ combined↗ 18.8 ms rise
↘ 12.4 ms fall
The screen shows slow response rates in our tests and will be unsatisfactory for gamers.
In comparison, all tested devices range from 0.8 (minimum) to 240 (maximum) ms. » 78 % of all devices are better.
This means that the measured response time is worse than the average of all tested devices (26.9 ms).
       Response Time 50% Grey to 80% Grey
40.8 ms ... rise ↗ and fall ↘ combined↗ 19.2 ms rise
↘ 21.6 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. » 46 % of all devices are better.
This means that the measured response time is similar to the average of all tested devices (43 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: 58 % of all tested devices do not use PWM to dim the display. If PWM was detected, an average of 5519 (minimum: 43 - maximum: 142900) Hz was measured.

För

+ oklanderlig kvalitet
+ utmärkt batteritid
+ ljusstark, matt skärm
+ attraktiv design
+ tyst och diskret
+ bra prestanda överlag

Emot

- väldigt tydligt spoltjut
- saknar fysisk dockningsport (och stöd för äldre dockningsstationer)
- pekpinnens placering är inte optimal
- CPU-prestanda under par
- inte lika lätt som konkurrenterna

Även om den inte är lika elegant som Dells egna 13- och 15-tums XPS-modeller är Latitude 7480 på något sätt ändå en proffsvariant av de lovordade konsumentmaskinerna. Den snygga 14-tummaren är mindre och mycket lättare än tidigare, men byggkvaliteten är otvivelaktigt hög. 

Chassit är styvt med snäva toleranser och har en mjuk, beröringsvänlig finish. Skärmen är ljusstark, med noggranna färger och få reflexer. Prestandan är också utmärkt; även om vissa CPU-specifika tester inte når hela vägen utmärker sig datorn i syntetiska prestandatester. Och batteriet räcker hela dagen även om det inte är fulladdat. Inmatningsenheterna är mycket bra – särskilt tangentbordet, som vi tycker är ett av de bästa på marknaden för närvarande.

Om det finns något stort minus är det ”spoltjutet” som hörs från minst 3 meters avstånd och verkar vara finnas närvarande oavsett belastning (men är naturligtvis mest märkbart när datorn går på lågvarv). Vi hoppas verkligen att det bara är vår testmodell som för oväsen, men med tanke på att vi hörde samma typ av oljud även när vi testade Latitude 5480 och 7280 skulle vi inte bli överraskade om det är ett vanligt problem.
