Test: HP EliteBook 755 G5 (Ryzen 7 2700U, Vega 10) Laptop (Sammanfattning)

Mike Wobker (översatt av Daniel Eriksson), 07/24/2018

AMD för Företaget. HP:s EliteBook-modeller erbjuder en attraktiv design, AMD-teknologi och många säkerhetsfunktioner. Men dessa kontorsmodeller har ofta stått ut från mängden på grund av hög energiförbrukning, låg kvalitet på skärmen och medioker batteritid. I vår recension utvärderar vi HP EliteBook 755 G5 och undersöker huruvida något av detta har förändrats i den senaste generationen.

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
32 ms ... rise ↗ and fall ↘ combined↗ 18 ms rise
↘ 14 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. » 82 % of all devices are better.
This means that the measured response time is worse than the average of all tested devices (25.9 ms).
       Response Time 50% Grey to 80% Grey
39 ms ... rise ↗ and fall ↘ combined↗ 20 ms rise
↘ 19 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. » 40 % of all devices are better.
This means that the measured response time is similar to the average of all tested devices (41.4 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 21000 Hz ≤ 90 % brightness setting

The display backlight flickers at 21000 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 21000 Hz is quite high, so most users sensitive to PWM should not notice any flickering.

In comparison: 54 % of all tested devices do not use PWM to dim the display. If PWM was detected, an average of 8895 (minimum: 43 - maximum: 142900) Hz was measured.

HP erbjuder en kultiverad generationsuppdatering åt den som köper EliteBook 755 G5. Dess AMD Ryzen 7-2700U CPU presterar bra, men det kunde ha varit ännu bättre med mer optimerad kylning. Den löstagbara bottenplattan låter användaren komma åt insidan för att utföra underhåll. Den goda färgrymdstäckningen motarbetas något av hög svärta och låg kontrast.

HP EliteBook 755 G5 är en tilltalade företagslaptop som har tillräckligt med prestanda även för mer krävande uppgifter samt batteritid för en hel arbetsdag.

Köparen får en presentabel enhet med attraktiv design och tillräckligt med batteritid för en hel arbetsdag. Det faktum att energiförbrukningen är högre än hos många andra enheter har inga allvarliga konsekvenser och bortsett från det finns det knappt någon anledning att tala emot ett köp av HP EliteBook 755 G5.
