Test: Lenovo ThinkPad E470 (HD-Skärm, HD 620) Laptop (Sammanfattning)

Name: Lenovo ThinkPad E470
Brand: Lenovo

Skärm från stenåldern. Lenovos Thinkpad E470 är en prisvärd ThinkPad med sin största användarbas bland studenter och hemmakontors-användare. Vi har redan recenserat den här laptopen tidigare i år. Men idag recenserar vi en modell med aningen sämre hårdvara för att förklara varför du inte borde skaffa den här datorn i den här specifika konfigurationen. Någonsin!

Display Response Times

ℹ

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
14 ms ... rise ↗ and fall ↘ combined	↘ 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 0.1 (minimum) to 240 (maximum) ms. » 29 % of all devices are better. This means that the measured response time is better than the average of all tested devices (21.5 ms).
↔ Response Time 50% Grey to 80% Grey
44 ms ... rise ↗ and fall ↘ combined	↗ 22 ms rise
44 ms ... rise ↗ and fall ↘ combined	↘ 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 0.2 (minimum) to 636 (maximum) ms. » 69 % of all devices are better. This means that the measured response time is worse than the average of all tested devices (33.7 ms).

Screen Flickering / PWM (Pulse-Width Modulation)

ℹ

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 Hz

≤ 90 % brightness setting

The display backlight flickers at 200 Hz (worst case, e.g., 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: 53 % of all tested devices do not use PWM to dim the display. If PWM was detected, an average of 17924 (minimum: 5 - maximum: 3846000) Hz was measured.

Slutsatsen är att E470 är en prisvärd företagsdator, men vi kan inte rekommendera den specifika konfiguration som vi recenserat idag.

Den delar många av sina fördelar med den andra E470: bekväma och dugliga inmatningsenheter med det närmast legendariska ThinkPad-tangentbordet och "track point"-pekutrustningen; ett stabilt och välgjort skal som, även om det inte är det tjusigaste får jobbet gjort väldigt väl; ett snabbt Wi-Fi modem och pålitlig applikationsprestanda - allt du kan förvänta dig från E470. Dom två aspekter som dagens recensionex slår den andra recenserade 940MX-utrustade ThinkPad E470 (Core i5, GeForce 940MX) är ett svalare system och längre batteritid. Avsaknaden av en Nvidia-GPU gör hela datorn mycket svalare och tystare och den låga skärmupplösningen resulterar i förbättrad batteritid.

Det är, dock, HD-skärmens enda fördel. I övrigt är skärmen katastrofal: alldeles för hög svärta, fruktansvärt smal betraktningsvinkel och en färgrymdstäckning som inte är värdig namnet. Vidare använder den PWM för ljusstyrke-modulering på väldigt låga frekvenser.

Vi kan inte rekommendera den specifika E470-modellen som recenseras tack vare dess obalanserade konfiguration och dess katastrofala skärm. Är du intresserad av E470, se till att du skaffar IPS-skärmen.

Bara detta är nog för att neka en rekommendation av E470. Nästan 6 700 SEK ($800) är helt enkelt för mycket för en laptop med en så dålig skärm som det här. Skulle du vara intresserad av E470 se till att du skaffar FHD IPS-skärmen. Oavsett så är E470 långt ifrån perfekt. Vi saknar exempelvis en USB-C port och Lenovos vanliga begränsade garanti på bara 12 månader är på den korta sidan. Vi kan leva med dessa nackdelar med tanke på datorns låga pris, men skärmen gör att det inte blir någon affär. Enheten var dessutom inkapabel att leverera sin maximala prestanda på batteri, och därför fick den slutgiltiga poängen minskas i enlighet med detta.
