Test: Lenovo Ideapad 720S-15IKB (i7-7700HQ, GTX 1050 Ti Max-Q, SSD 512 GB) Laptop (Sammanfattning)

Sven Kloevekorn (översatt av Daniel Eriksson), 08/28/2018

Ett multimediaoriginal. Lenovo har utrustat sin första modell på 15 tum ur 700-serien med exotisk hårdvara, inklusive en i7-7700HQ med TDP reducerad till 35 Watt samt ett 1050 Ti Max-Q. Denna kandidat har mycket att erbjuda — en utmärkt skärm, lång batteritid — men flugan i soppan, så att säga, kan vara ett hinder för vissa.

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
25 ms ... rise ↗ and fall ↘ combined↗ 14 ms rise
↘ 11 ms fall
The screen shows relatively slow response rates in our tests and may be too slow for gamers.
In comparison, all tested devices range from 0.8 (minimum) to 240 (maximum) ms. » 39 % of all devices are better.
This means that the measured response time is similar to the average of all tested devices (25.8 ms).
       Response Time 50% Grey to 80% Grey
34 ms ... rise ↗ and fall ↘ combined↗ 15 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. » 22 % of all devices are better.
This means that the measured response time is better than the average of all tested devices (41.3 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 25000 Hz ≤ 40 % brightness setting

The display backlight flickers at 25000 Hz (Likely utilizing PWM) Flickering detected at a brightness setting of 40 % and below. There should be no flickering or PWM above this brightness setting.

The frequency of 25000 Hz is quite high, so most users sensitive to PWM should not notice any flickering.

In comparison: 53 % of all tested devices do not use PWM to dim the display. If PWM was detected, an average of 8813 (minimum: 43 - maximum: 142900) Hz was measured.

Efter några veckor tillsammans med Lenovo Ideapad 720S-15IKB tycker vi fortfarande att dess hårdvarukonfiguration är en aning underlig, även om den är fullt rimlig. En i7-7700HQ med ett TDP reducerat till 35 watt har ett kuriosavärde, och med tanke på systemets problem med värmeregulering undrar vi om Lenovo helt enkelt har strypt processorn för att de var tvungna. Trots denna underlighet är processorns prestanda mer än tillräcklig för tunga applikationer och intensiv multitasking. Det är sällan processorn som är flaskhalsen — den minimalt strypta Max-Q versionen av Nvidia GeForce 1050 Ti får spela den rollen, i huvudsak när den renderar spel med höga hårdvarukrav.

För en enhet i den här klassen — inklusive vid direkt jämförelse med de andra bärbara datorer vi behandlat i den här recensionen — kommer det sällsynt magra utbudet av portar definitivt vara ett hinder för många intresserade köpare. Att tvinga användare att bära runt på adaptrar som behöver köpas separat är en garanterad metod för att bli av med kunder. Vi kan inte överhuvudtaget förklara avsaknaden av en separat HDMI- och/eller DisplayPort-anslutning, särskilt med tanke på att det finns gott om plats tillgängligt. Mindre viktiga nackdelar inkluderar suboptimal WLAN-mottagning och skärmbleeding som bara syns när bildmaterialet är väldigt mörkt.

Även om Lenovo Ideapad 720S-15IKB på de flesta vis är en attraktiv enhet så gör dess problematiska värmeregulering och framför allt bristen på fysiska anslutningar att vi inte riktigt känner att vi kan rekommendera den.

På plus-sidan kan vi addera: Ett nedtonat men ändå gediget och ergonomiskt hölje, uppdaterade säkerhetsfunktioner, bra skärm och sist men inte minst att systemet har en ekonomisk energiförbrukning och uppför sig tyst — för att inte tala om den rikliga batteritiden som har rejält med reserver inför framtiden. Även om vi anser att Lenovos Ideapad totalt sett är en framgång — vilket märks på vårt omdöme på 87%, bara precis under omdömet "riktigt bra" — så är det till största del avsaknaden av anslutningar som hindrar enheten från att få vårt rekommendations-sigill. Å andra sidan, om du gör det mesta trådlöst och tänker dig att du klarar dig med de portar som finns, eller inte har något emot tanken på att bära runt på extra adaptrar, så kan Ideapad ändå vara ett bra val.
