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 ms ... rise ↗ and fall ↘ combined↗ 9 ms rise
↘ 16 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. » 34 % of all devices are better.
This means that the measured response time is similar to the average of all tested devices (27.2 ms).
       Response Time 50% Grey to 80% Grey
43 ms ... rise ↗ and fall ↘ combined↗ 20 ms rise
↘ 23 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. » 54 % of all devices are better.
This means that the measured response time is similar to the average of all tested devices (44 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 204 Hz90 % brightness setting

The display backlight flickers at 204 Hz (Likely utilizing PWM) Flickering detected at a brightness setting of 90 % and below. There should be no flickering or PWM above this brightness setting.

The frequency of 204 Hz is relatively low, so sensitive users will likely notice flickering and experience eyestrain at the stated brightness setting and below.

In comparison: 59 % of all tested devices do not use PWM to dim the display. If PWM was detected, an average of 2255 (minimum: 43 - maximum: 142900) Hz was measured.

- skärm med låg kontrast och begränsade betraktningsvinklar

Läs en längre version av testet på engelska här.

Tyvärr kan inte HP presentera en balanserad konfiguration som motiverar den höga prislappen. Det är helt klart en ambitiöst enhet, men enligt vår mening är en TN-panel med begränsade betraktningsvinklar, dålig kontrast och färgreproduktion inte OK i prisklassen, vilket också återspeglas i betyget. Därför hamnar den på en klar andraplats efter Dell Latitude E7470.

EliteBook 840 är definitivt ingen dålig dator. Batteritid, dockningsalternativ, uppgraderingsmöjligheter, utmärkta inmatningsenheter och naturligtvis prestandan är några av många positiva aspekter med 14-timmaren. 3K-versionen av 840 G3 med 2560x1440 pixlar kan vara kandidat för en topplacering, eftersom man där använder en IPS-panel utan pekfunktion (WQHD-UWVA).

Uppdatering 2016/04/18: 

HP erbjuder mycket riktigt en utmärkt halvmatt WQHD-panel som tillval för EliteBook 840 G3. Den är överlägsen TN-modellen i alla avseenden utom utomhus, där antireflexbehandlingen är mer effektiv med TN-panelen. 

Tyvärr sjunker batteritiden med 1,5 timmar i Wi-Fi-testet med WQHD panelen. Det minskar fördelen med IPS-modellen lite, men bildkvaliteten kommer förmodligen att vara viktigare för de allra flesta. Med den bättre skärmen skulle HP 840 G3 WQHD få en totalpoäng på 88%.
