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
32.8 ms ... rise ↗ and fall ↘ combined↗ 16.4 ms rise
↘ 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 0.8 (minimum) to 240 (maximum) ms. » 84 % of all devices are better.
This means that the measured response time is worse than the average of all tested devices (24.4 ms).
   ↔    Response Time 50% Grey to 80% Grey
54.4 ms ... rise ↗ and fall ↘ combined↗ 26.8 ms rise
↘ 27.6 ms fall
The screen shows slow response rates in our tests and will be unsatisfactory for gamers.
In comparison, all tested devices range from 0.8 (minimum) to 636 (maximum) ms. » 88 % of all devices are better.
This means that the measured response time is worse than the average of all tested devices (38.7 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: 51 % of all tested devices do not use PWM to dim the display. If PWM was detected, an average of 9717 (minimum: 5 - maximum: 142900) Hz was measured.

Omdöme - Fujitsu Lifebook U939X kunde varit ännu bättre

Även om Fujitsu Lifebook U939X lämnade ett gott intryck finns det också anledning att klaga. På den positiva sidan har den en riktigt bra tryckkänslig skärm som inte bara har bra skärmvärden utan också en icke-reflekterande yta. Den har bra anslutningsutrustning, och med två Thunderbolt 3-portar får man ytterligare frihet att skapa egna anslutningar med hjälp av adaptrar. Bra batteritid rundar av alltihop.

Lifebook U939X hade varit en nästan perfekt omvandlingsbar om Fujitsu bara förbättrat styrplattan och tangentbordet.

Med start i Juli borde det finnas processorer från Comet Lake-generationen till Fujitsus Lifebook-modeller, så faktum att processorn inte riktigt är modern längre gör inte så mycket. Prestandan ligger på en bra nivå och den kan fortfarande vara ett intressant val om priset är rätt. Trots att den saknar stöd för WiFi 6 lämpar sig WLAN-prestandan ändå väl för vardagsarbete.

Men denna i övrigt utmärkta omvandlingsbara dator får ta emot kritik för sitt tangentbord och sin styrplatta. Mjuk återkoppling när man skriver och ett lätt klapprande läte från musersättningen lämnar inte ett gott intryck för en enhet i det här prisskiktet. Man får därför fundera över huruvida de positiva egenskaperna Fujitsu Lifebook U939X besitter är viktigare än de negativa.
