Test: Lenovo IdeaPad S540-15IML - Utmärkt batteritid (Sammanfattning)

Name: Lenovo Ideapad S540-15IML
Brand: Lenovo

Spegel spegel på väggen där. I vårt test imponerade 15-tummaren IdeaPad S540-15IML inte bara med sitt högkvalitativa metallhölje utan även med utmärkt batteritid. Men vi förstår inte riktigt varför Lenovo valt en blank skärm.

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
34.8 ms ... rise ↗ and fall ↘ combined	↗ 18.8 ms rise
34.8 ms ... rise ↗ and fall ↘ combined	↘ 16 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 (21.5 ms).
↔ Response Time 50% Grey to 80% Grey
49.6 ms ... rise ↗ and fall ↘ combined	↗ 22.4 ms rise
49.6 ms ... rise ↗ and fall ↘ combined	↘ 27.2 ms fall
The screen shows slow response rates in our tests and will be unsatisfactory for gamers. In comparison, all tested devices range from 0.2 (minimum) to 636 (maximum) ms. » 83 % of all devices are better. This means that the measured response time is worse than the average of all tested devices (33.7 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 detected

202 Hz

≤ 99 % brightness setting

The display backlight flickers at 202 Hz (worst case, e.g., utilizing PWM) Flickering detected at a brightness setting of 99 % and below. There should be no flickering or PWM above this brightness setting.

The frequency of 202 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 17900 (minimum: 5 - maximum: 3846000) Hz was measured.

- Kraftigt reflekterande skärm

Lenovo IdeaPad S540-15IML, recensionsenhet från:

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

En mästare på uthållighet med ett tjusigt metallhölje för 8.000 kronor? Det låter otroligt men så är fallet med Lenovo IdeaPad S540-15IML.

Det finns knappt någon annan allt-i-allo laptop som klarar sig så bra utan nätadapter. Tillsammans med låg vikt (1.9 kg) och platt konstruktion (1.7 cm) är denna 15-tummare som gjord för mobilt bruk.

Om det bara inte vore för den blanka skärmen som gör utomhusaktiviteter och till och med en del inomhusaktiviteter frustrerande. En matt skärm hade passat enheten mycket bättre och hade framför allt passat hela konceptet bättre.

Om du kan acceptera den bristen får du däremot en i stort riktigt framgångsrik multimedialaptop som vi kan rekommendera.
