Test: Chuwi LapBook Air 14.1 (N3450, FHD) Laptop (Sammanfattning)

Allen Ngo (översatt av Daniel Eriksson), 11/08/2017

Attraktiv och långsam. Chuwis MacBook Air-klon ser definitivt bra ut och kan lätt misstas för en dubbelt så dyr Ultrabook. Gå ner på djupet och du kommer dock hitta små brister som snabbt blir till sprickor.

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
29.2 ms ... rise ↗ and fall ↘ combined↗ 16 ms rise
↘ 13.2 ms fall
The screen shows relatively slow response rates in our tests and may be too slow for gamers.
In comparison, all tested devices range from 0.8 (minimum) to 240 (maximum) ms. » 69 % of all devices are better.
This means that the measured response time is similar to the average of all tested devices (26.6 ms).
       Response Time 50% Grey to 80% Grey
32.8 ms ... rise ↗ and fall ↘ combined↗ 12.8 ms rise
↘ 20 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. » 18 % of all devices are better.
This means that the measured response time is better than the average of all tested devices (42.5 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 detected 200 Hz20 % brightness setting

The display backlight flickers at 200 Hz (Likely utilizing PWM) Flickering detected at a brightness setting of 20 % and below. There should be no flickering or PWM above this brightness setting.

The frequency of 200 Hz is relatively low, so sensitive users will likely notice flickering and experience eyestrain at the stated brightness setting and below.

In comparison: 54 % of all tested devices do not use PWM to dim the display. If PWM was detected, an average of 8586 (minimum: 43 - maximum: 142900) Hz was measured.

In review: Chuwi LapBook Air 14.1. Test model provided by Chuwi

LapBook Air ser ut och känns fantastisk med tanke på dess låga utgångspris på ~3 400 SEK (400$). IPS-skärmen på 1080p är skarp, en sekundär intern enhetsplats är sällsynt och tangentbordet är till och med bakgrundsbelyst. Tyvärr behövde tillverkaren göra nedskärningar på nästan allt annat för att nå det otroligt låga rekommenderade priset.

Till att börja med så är kvalitetskontrollen inte på samma nivå som på många välkända alternativ. Vår testenhet led av måttlig bleeding på skärmens bakgrundsbelysning, ojämn bakgrundsbelysning för tangentbordet, en trasig Ctrl-tangent, en bristfällig USB-port, flera krascher och en böjd kant. Vi rekommenderar nya ägare att testa varje port och knapp för att försäkra sig om att inget är skadat. För det andra så är den passivt kylda Celeron-processorn, den primära SSD-disken och laddaren är alla väldigt långsamma. Användare som vill ha något lite kraftigare skulle klara sig bättre med en äldre ULV Haswell-laptop som troligen kommer ha fastare tangentbordsknappar och mer exakta styrplatta. Om den i huvudsak används för strömning och videouppspelning på resande fot så är LapBook Air ändå inte dålig.

LapBook kan visa sig användbar för dom som bara planerar att surfa, ordbehandla och strömma film.
