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: 51 % of all tested devices do not use PWM to dim the display. If PWM was detected, an average of 17520 (minimum: 5 - maximum: 2500000) Hz was measured.

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
25.6 ms ... rise ↗ and fall ↘ combined↗ 12.4 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. » 46 % of all devices are better.
This means that the measured response time is similar to the average of all tested devices (24.4 ms).
       Response Time 50% Grey to 80% Grey
38.8 ms ... rise ↗ and fall ↘ combined↗ 19.6 ms rise
↘ 19.2 ms fall
The screen shows slow response rates in our tests and will be unsatisfactory for gamers.
In comparison, all tested devices range from 0.8 (minimum) to 636 (maximum) ms. » 42 % of all devices are better.
This means that the measured response time is similar to the average of all tested devices (38.7 ms).

Omdöme: Redmi Note 9 - En utmärkt väg in i smartphone-världen

Recension av Redmi Note 9. Recensionsex från notebooksbilliger.de.
Recension av Redmi Note 9. Recensionsex från notebooksbilliger.de.

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

Xiaomi gör reklam för sin billiga mittenskiktstelefon med orden "Allt du behöver". Mobiltillverkaren från Shenzhen har inte helt fel i detta, för Redmi Note 9 ger en riktigt bra smartphone-upplevelse för ett butikspris på runt 1.500 kronor. Men vi rekommenderar definitivt att du lägger 200 kronor extra på att skaffa modellen med 4 GB.

Letar du efter en billig smartphone för under 2.000 kronor bör du definitivt överväga Redmi Note 9.

Jämfört med Redmi 9 har Note-modellen en bättre högtalare och en trevligare huvudkamera. En mer ljusstark IPS-skärm som definitivt har bättre kontrast och stabilare betraktningsvinklar ger också en märkbar fördel i vardagen. Dessutom kommer Note 9 med en snabb laddare som standard.

Men Redmi Note 9 är och förblir en instegstelefon. Du får därför stå ut med en del kompromisser när det kommer till processorn, kamerans kvalitet (i synnerhet ultra-vidvinkelkameran) samt lagrings- och WLAN-hastigheterna.
