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
34.4 ms ... rise ↗ and fall ↘ combined	↗ 18 ms rise
34.4 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. » 91 % 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
62.4 ms ... rise ↗ and fall ↘ combined	↗ 25.6 ms rise
62.4 ms ... rise ↗ and fall ↘ combined	↘ 26.8 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. » 97 % 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

211.9 Hz

≤ 30 % brightness setting

The display backlight flickers at 211.9 Hz (worst case, e.g., utilizing PWM) Flickering detected at a brightness setting of 30 % and below. There should be no flickering or PWM above this brightness setting.

The frequency of 211.9 Hz is relatively low, so sensitive users will likely notice flickering and experience eyestrain at the stated brightness setting and below.

In comparison: 53 % of all tested devices do not use PWM to dim the display. If PWM was detected, an average of 8705 (minimum: 5 - maximum: 343500) Hz was measured.

Omdöme - Lifebook U9310X är fortfarande en extremt mobil omvandlingsbar med många portar

Recension av Fujitsu Lifebook U9310X. Recensionsex från Fujitsu Germany.

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

Fujitsu uppgraderar bara sin omvandlingsbara kontorslaptop Lifebook UX9310X lite grann, för bortsett från WiFi 6-modulen och Comet Lake-processorn är det inget som har ändrats. Dess största styrka är fortfarande det robusta och lätta magnesiumhöljet samt de många portarna och säkerhetsfunktionerna. Du behöver inte förlita dig på adaptrar här inte. Dessutom är den med sin matta tryckkänsliga skärm mångsidig i egenskap av omvandlingsbar och tack vare inbyggt stöd för LTE är du alltid ansluten till internet. Batteritiden är också bra.

Den är inte överväldigande kraftfull men är fullt tillräcklig för många vanliga kontorsprogram. Prestandan sänks dock betydligt vid batteridrift (i synnerhet för dess iGPU). Temperaturen och ljudnivån håller sig däremot inom gränserna.

Fujitsu Lifebook U9310X övertygar med sin mobilitet och har utförliga anslutningsmöjligheter samt inbyggt stöd för LTE. Men till nästa uppdatering ser vi gärna bättre inmatningsenheter och en 16:10-skärm.

Inmatningsenheterna är fortfarande en svag punkt. De är inte dåliga, men andra omvandlingsbara kontorsmodeller har en tydlig fördel. Fujitsu bör definitivt behålla den matta tryckkänsliga skärmen, men vi hade gärna sett ett byte till en 16:10-panel. Vi räknar också med att nästa modell byter till Intels Tiger Lake-processorer eller kanske till och med AMD:s Ryzen, även om AMD just nu knappt återfinns i kategorin för omvandlingsbara kontorsmodeller alls (vilket gäller nästan alla tillverkare).
