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 9533 (minimum: 43 - maximum: 142900) Hz was measured.

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 ms ... rise ↗ and fall ↘ combined	↗ 17 ms rise
32 ms ... rise ↗ and fall ↘ combined	↘ 15 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. » 81 % of all devices are better. This means that the measured response time is worse than the average of all tested devices (25.2 ms).
↔ Response Time 50% Grey to 80% Grey
46 ms ... rise ↗ and fall ↘ combined	↗ 25 ms rise
46 ms ... rise ↗ and fall ↘ combined	↘ 21 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. » 72 % of all devices are better. This means that the measured response time is worse than the average of all tested devices (40.3 ms).

Lenovo Tab 4 8. Review unit courtesy of notebooksbilliger.de

Lenovos Tab 4 8 är en prisvärd surfplatta som misslyckas med att stå ut. Dess design är ganska återhållsam och konservativ, skalet är mottagligt för vridning och tryck och kameraupplösning, bildkvalitet, prestanda och anslutbarhet är typiska för dess klass.

Med andra ord: Lenovos surfplatta är inte speciell på något vis men är samtidigt pålitlig på många sätt. Den ljusstarka skärmens betraktningsvinkel är superb, dess GPS är exakt och enheten blir inte särskilt varm under belastning. Dom framåtriktade högtalarna, dess rena version av Android och dess stor batteri (som Lenovo dock inte lyckats krama någon extra batteritid ur) är särskilt noterbara. Den kan göras barnsäker med valfria tillbehör och vi vill återigen betona faktumet att tvärt emot många andra tillverkade så har Lenovo faktiskt spenderat tid, pengar och energi på att fundera över hur man kan förbättra en billig surfplatta med tillbehör.

Lenovo Tab 4 8 är en pålitlig 8-tums surfplatta utan några särskilda finesser men som har en solid prestanda i övrigt.

Allt som allt, surfplattor som Lenovos Yoga-serie är mycket mer innovativa än Tab 4 8. Men den senare erbjuder pålitlig prestanda utan några egentliga brister för ett hyfsat pris.
