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
18 ms ... rise ↗ and fall ↘ combined↗ 14 ms rise
↘ 4 ms fall
The screen shows good response rates in our tests, but may be too slow for competitive gamers.
In comparison, all tested devices range from 0.8 (minimum) to 240 (maximum) ms. » 10 % of all devices are better.
This means that the measured response time is better than the average of all tested devices (26.7 ms).
       Response Time 50% Grey to 80% Grey
45 ms ... rise ↗ and fall ↘ combined↗ 27 ms rise
↘ 18 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. » 68 % of all devices are better.
This means that the measured response time is similar to the average of all tested devices (42.8 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 1000 Hz90 % brightness setting

The display backlight flickers at 1000 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 1000 Hz is quite high, so most users sensitive to PWM should not notice any flickering.

In comparison: 57 % of all tested devices do not use PWM to dim the display. If PWM was detected, an average of 6272 (minimum: 43 - maximum: 142900) Hz was measured.

A HP EliteBook 755 G4 egy 15 inches üzleti laptop. Az AMD processzor elegendő a tervezett használathoz, de van pár hátránya. A processzoron kívül az általunk tesztelt  gépben 8 GB DDR4 RAM és egy gyors, 256 GB-os, M.2-2280 SSD  található, és jelenleg 1460 euróba (~$1650) kerül. A szerelési minőségre nem lehet panaszunk. Az elegáns és visszafogott designra szintén nem. A jó anyagválasztásnak köszönhetően stabil és elég jól használható a mindennapokban.

A HP EliteBook 755 G4 jó üzleti gép, amely belépő szintű volta ellenére sok biztonsági funkcióval fel van szerelve. Akinek az AMD processzor teljesítménye nem kevés, az HP EliteBook 755 G4 képében egy modern csatlakozókkal felszerelt, jó notebookot kap.

A legkomolyabb problémánk a kijelzővel volt, amelytől valamivel kevéssé jól csiszolt a gép összhatása. A panel minősége egyszerűen nem illik az EliteBook szériához. A gyártónak nem ártana felülvizsgálnia, hogy vajon ez a minőség illik-e a célközönség igényeihez. A másik komolyabb panaszunk a processzor energiaéhsége, amely lerövidíti a telep üzemidejét.

A szervizfedél hiánya kisebb probléma, mivel amúgy nem nehéz eltávolítani az alsó burkolatot, csak szerintünk felhasználóbarátabb lett volna egy szervizfedeles megoldás. A hangminőség, billentyűzet és a gyors SSD viszont kifejezetten tetszettek.
