HP EliteBook 840 G4 (7200U, Full HD) Laptop rövid értékelés

Andreas Osthoff (fordította Tamás Somogyi), 03/24/2017
Business Kaby Lake Laptop / Notebook Windows

Alig változott. A HP már az üzleti noteszgépeit is Kaby Lake-es processzorokkal szereli fel, de amúgy nem sokat változtat rajtuk. Ez a kijelzőre is igaz, amely ugyan elég világos, de minden más területen kiábrándító.

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
23 ms ... rise ↗ and fall ↘ combined↗ 6 ms rise
↘ 17 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. » 29 % of all devices are better.
This means that the measured response time is similar to the average of all tested devices (25.3 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. » 41 % of all devices are better.
This means that the measured response time is similar to the average of all tested devices (40.4 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 not detected

In comparison: 51 % of all tested devices do not use PWM to dim the display. If PWM was detected, an average of 9554 (minimum: 43 - maximum: 142900) Hz was measured.

In review: HP EliteBook 840 G4. Test model courtesy of Notebook.de

Az új HP EliteBook 840 G4 lényegében az előd, a G3 modell Kaby Lake-es frissítése. A mérete és a ház minősége még mindig jól tartja magát a versenytársakkal szemben, csak pár apróság, mint a nyekergő zsanérok és a kattogós touchpad gombok rontják le a benyomást kissé. Az alkatrészek hozzáférhetősége is pozitívum: a RAM bővítése például pofonegyszerű. A beviteli eszközöket továbbra is szerettük, főleg a billentyűzetet.

A 14 inches üzleti laptop nem okoz csalódást teljesítmény és emissziók terén sem. A gép csendes, nem melegszik túl, és az Intel Core i5-7200U elég jól ki tudja használni a teljesítménypotenciálját. A HP a telep kapacitását is növelte, ennek eredményeképp majdnem 10 óra üzemidőt kapunk.

Jó ház, kis kibocsátások, elégséges teljesítmény – a HP EliteBook 840 negyedik generációja kiváló üzleti notebook lehetne. Ezt azonban megakadályozza a pocsék TN panel, amelynek semmi keresnivalója nem lenne egy 1500 euró (~$1614) feletti árú gépben.

Az, hogy a HP csak ráncfelvarrásokat végzett idén az EliteBook-on, nyilvánvalóvá válik a csatlakozókat megnézve. Ugyan minden, az irodában fontosat megkapunk, de az időtállóságot biztosító Thunderbolt 3 kimaradt.

A legnagyobb probléma ugyanakkor a Full HD TN display. A fényerő és a felbontás rendben vannak, de a panel minden más téren kiábrándítóan teljesít. A korlátozott betekintés gyakorlatban komoly gond. Egy ilyen panelnak nincs helye egy 1500 eurónál (~$1614) drágább laptopban. Akinek az EliteBook 840 felkeltette az érdeklődését, annak mindenképpen érdemes IPS kijelzős modellt választania. Az általunk tesztelt TN kijelzőset nem ajánljuk.
