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
35.2 ms ... rise ↗ and fall ↘ combined↗ 21.2 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. » 90 % of all devices are better.
This means that the measured response time is worse than the average of all tested devices (26.2 ms).
       Response Time 50% Grey to 80% Grey
48.8 ms ... rise ↗ and fall ↘ combined↗ 24.8 ms rise
↘ 24 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. » 80 % of all devices are better.
This means that the measured response time is worse than the average of all tested devices (41.9 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: 54 % of all tested devices do not use PWM to dim the display. If PWM was detected, an average of 10287 (minimum: 43 - maximum: 588200) Hz was measured.

Dell har gjort nästan allt rätt med nya Latitude 7390. För inte mer än 14 000 kronor för modellen vi testat får man ett välavrundat paket som bara har ett fåtal brister.

Här borde vi nämna det aningen pyttiga men i övrigt i stort framgångsrika tangentbordet, den tveksamma ersättningen för musknappar, avsaknaden av Thunderbolt 3 och den högljudda mellanslags-tangenten. Det är ett mindre snedsteg att locket får basen att resa sig om det öppnas i en vinkel över 135°. Det enda vi verkligen inte gillade var det vidriga ljudet och den suboptimala fingeravtrycksläsaren.

Punkterna på "Fördels"-listan är inte bara många utan också i huvudsak viktigare. Även om Latitude med sin i5-8350U är lite av en överdrift för kontorsarbete så känner vi att mer kraft aldrig kan skada, med tanke på att batteritiden fortfarande är på en hög nivå. Det enkelt designade men högkvalitativa höljet, inmatningsenheterna som går från bra till riktigt bra, den kompletta säkerhetsutrustningen, dom vettiga anslutningarna, skärmen med hög kontrast, Windows 10 Pro och sist men inte minst 3 års garanti tillsammans med tyst drift förtjänar en klar köprekommendation.
