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
17.6 ms ... rise ↗ and fall ↘ combined↗ 3.6 ms rise
↘ 14 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. » 34 % 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
28.4 ms ... rise ↗ and fall ↘ combined↗ 11.2 ms rise
↘ 17.2 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 0.2 (minimum) to 636 (maximum) ms. » 32 % of all devices are better.
This means that the measured response time is better than the average of all tested devices (33.7 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 222.2 Hz ≤ 49 % brightness setting

The display backlight flickers at 222.2 Hz (worst case, e.g., utilizing PWM) Flickering detected at a brightness setting of 49 % and below. There should be no flickering or PWM above this brightness setting.

The frequency of 222.2 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 17900 (minimum: 5 - maximum: 3846000) Hz was measured.

För

+ smart stativdesign som förbättrar komforten
+ bra WLAN-prestanda
+ bekvämt tangentbord
+ rymlig och exakt pekplatta med bra integrerade knappar
+ skärm med bra färgrymd
+ bra generell systemprestanda
+ moduler som säljs separat är ett tilltalande koncept
+ underhåll är möjligt via den löstagbara bakpanelen

Emot

- chassit är styvt, men inte lika vridstyvt som Surface m.fl. konkurrenter
- svår att bära med en hand när den är öppen
- medelmåttig ljusstyrka och kontrast jämfört med konkurrenterna
- PWM vid alla ljusstyrkor upp till 49 procent
- kontinuerlig CPU/GPU-prestandan resulterar i strypning
- GPU-prestandan är t.o.m. sämre än med m3-modellen av Surface Pro
- mediokra högtalare
- batteritiden är en bra bit under genomsnittet
- dyr

In review: Lenovo ThinkPad X1 Tablet. Test model provided by Lenovo US.

Lenovo var en av pionjärerna på tabletmarknaden för länge sedan, men med X1 Tablet vill man utmana Microsoft Surface-konceptet. Målet är gissningsvis att plattan ska vara ett företagsvänligt alternativ till Surface Pro – och på många sätt lyckas man med det. 

X1 Tablet har de bekväma inmatningsenheter vi har kommit att förvänta oss av en ThinkPad. Den har också bra prestanda för att vara passivt kyld. Underhållsmöjligheter finns också och en rad separata moduler kan köpas till för att utöka funktionalitet och portutbud. Vi blev också imponerade av stativets design, som gör användning i knät betydligt bekvämare än Surface Pro.

Den är dessvärre inte utan nackdelar. Användningen av plast för några delar av höljet gör enheten mindre vridstyv än modeller helt i magnesium (som Microsoft Surface Pro ). Maskinen går också varm (åtminstone konfigurationen vi testade), vilket gör den obekväm att använda under längre perioder. Vi ifrågasätter värdet av den dyrare Core-m7-konfigurationen som testas här, eftersom den extra prestandan förmodligen äts upp av den extra värmen. Slutligen är batteritiden sämre jämfört med nästan alla direkta konkurrenter.

Kanske kan man lindra flera av de här problemen genom att välja en billigare modell med Core m3 eller m5 istället, utan några nämnvärda uppoffringar vad gäller prestandan.
