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↗ 17.2 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. » 79 % 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
22.4 ms ... rise ↗ and fall ↘ combined↗ 10.8 ms rise
↘ 11.6 ms fall
The screen shows good response rates in our tests, but may be too slow for competitive gamers.
In comparison, all tested devices range from 0.9 (minimum) to 636 (maximum) ms. » 7 % of all devices are better.
This means that the measured response time is better 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.

Allt som allt var vi mycket nöjda med ZenBook 13 UX331UN. Den kommer med en högkvalitativ skärm och förvånansvärt dugliga högtalare, vilket är dom viktigaste ingredienserna för en multimedia-laptop som kan användas utomhus tack vare sin imponerande maximala skärmljusstyrka. Utöver det så är kombinationen av CPU och GPU kraftfull nog för at köra spel smidigt vid reducerad upplösning och detalj. På så sätt är ZenBook ett skolboksexempel på en sann mångsysslare. Den är tunn och lätt, har ett hölje av hög kvalitet, en väldigt bra styrplatta och håller sig för det mesta sval. Dessutom är batteritiden utmärkt trots ett genomsnittligt 50 Wh-batteri.

Tillsammans är dessa imponerande fördelar. Tyvärr är ZenBook ännu inte riktigt perfekt och har ett antal brister. Tangentbordet är bara halvdant, kylsystemet är inte tillräckligt kraftfullt, CPU-prestandan är inkonsekvent och processorn tenderar att strypas för tidigt eller för ofta (vilket vi kunde bekräfta i Cinebench R15 och vårt stresstest-scenario). Inte bara det, dess CPU är dessutom betydligt långsammare när datorn körs på batteri. Och låt oss inte glömma det oljud som ZenBook ger ifrån sig under belastning och vid spelande. Faktum är att det är på gränsen att kunna vara irriterande för den känsligare användaren. Sist men inte minst, den inbyggda SATA III SSD-enheten, avsaknaden av Thunderbolt 3 och den rejält begränsade USB-C porten (inget stöd för DisplayPort) är nackdelar som är värda att notera.

Lockande: I mångt och mycket har Asus lyckats träffa mitt i prick med ZenBook 13 UX331UN, på nästan alla områden.

Fördelarna väger tydligt upp nackdelarna, vilket är varför ZenBook 13 UX331UN förtjänar en rekommendation. På jakt efter en portabel laptop med en diskret GPU så är den definitivt ett strålande alternativ till Dell XPS 13.
