Lenovo ThinkPad E470 (HD-Display, HD 620) Laptop rövid értékelés

Benjamin Herzig (fordította Tamás Somogyi), 10/17/2017
Business Kaby Lake Ultrabook Notebook

Kőkorszaki kijelző. A Lenovo ThinkPad E470 egy megfizethető ThinkPad elsősorban diákoknak, és home office rendszerben dolgozóknak. Idén, korábban teszteltük már ezt a típust. Most egy valamivel gyengébb hardverrel felszerelt változatán keresztül bemutatjuk, hogy miért ne vegye meg ezt a notebookot, ebben a konfigurációban senki. Soha.

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
14 ms ... rise ↗ and fall ↘ combined↗ 8 ms rise
↘ 6 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. » 8 % of all devices are better.
This means that the measured response time is better than the average of all tested devices (26.6 ms).
       Response Time 50% Grey to 80% Grey
44 ms ... rise ↗ and fall ↘ combined↗ 22 ms rise
↘ 22 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. » 62 % of all devices are better.
This means that the measured response time is similar to the average of all tested devices (42.4 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 200 Hz90 % brightness setting

The display backlight flickers at 200 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 200 Hz is relatively low, so sensitive users will likely notice flickering and experience eyestrain at the stated brightness setting and below.

In comparison: 54 % of all tested devices do not use PWM to dim the display. If PWM was detected, an average of 8499 (minimum: 43 - maximum: 142900) Hz was measured.

Pro

+ jó ház
+ kényelmes beviteli eszközök
+ megfelelő rendszer teljesítmény
+ gyors Wi-Fi
+ terhelés alatt sem melegszik, és halk marad
+ javult az üzemideje

Kontra

- nincs USB-C
- csak 12 hó jótállás
- pocsék TN HD kijelző, szégyenteljes betekintéssel
- telepről működve a CPU visszafogja magát
- alacsony frekvenciás PWM vibrálás 90 % fényerő alatt

A teszt végkövetkeztetése, hogy az E470 egy megfizethető üzleti notebook, amelyet ebben a konfigurációban senkinek nem ajánlunk.

A többi E470-nel egy sor előnyön osztozik: kényelmes és jó beviteli eszközök (a majdnem legendának minősülő ThinkPad billentyűzet és trackpoint); stabil és jól összerakott ház, amely ugyan nem a legszebb, de a célnak tökéletesen megfelel; egy gyors Wi-Fi modem; jó alkalmazásteljesítmény. Két dologban felül is múlja a Lenovo ThinkPad E470 (Core i5, GeForce 940MX)-et: hűtés és üzemidő terén. A dedikált videokártya mellőzése, valamint az alacsony kijelző felbontás segített ezt elérni.

A HD kijelzőnek viszont ennyi az összes pozitívuma. Egyébiránt a panel pocsék: nagyon magas fekete értékek, rémesen szűk betekintési szög, a színlefedettség pedig gyalázatos. Ráadásul a fényerő modulációjára PWM-et használ, mégpedig igen alacsony frekvenciával.

Ezt az E470 modellt senkinek nem ajánljuk, mivel a konfigurációja nem kiegyenlített, a kijelzője pedig pocsék. Amennyiben az E470 tetszik, mindenképpen az IPS kijelzőre csapjunk le.

Ez már magában is elegendő ahhoz, hogy ezt az E470-et ne ajánljuk. Majdnem $800 egyszerűen túl sok egy ilyen rossz kijelzővel felszerelt notebookért. Amennyiben az E470 tetszik, mindenképpen az FHD IPS kijelzőre csapjunk le. Mindenesetre, az E470 messze nem tökéletes. Az USB-C -t hiányoljuk, a csak 12 hónapos, korlátozott garancia pedig elég kevés. Ezekkel még együtt is tudnánk élni, figyelembe véve az árát, de a kijelzővel nem. Ráadásul telepről működve a gép nem volt képes maximális teljesítményre, emiatt szintén pontokat kellett levonnunk a végső értékelésből.

Ez az eredeti értékelés rövidített változata. A teljes, angol nyelvű cikk itt olvasható.
