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 | ||
|---|---|---|
| 28.8 ms ... rise ↗ and fall ↘ combined | ↗ 17.2 ms rise |  |
| ↘ 11.6 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 0.1 (minimum) to 240 (maximum) ms. » 74 % of all devices are better. This means that the measured response time is worse than the average of all tested devices (20.9 ms). | ||
| ↔ Response Time 50% Grey to 80% Grey | ||
| 40.4 ms ... rise ↗ and fall ↘ combined | ↗ 22.4 ms rise |  |
| ↘ 18 ms fall | ||
| The screen shows slow response rates in our tests and will be unsatisfactory for gamers. In comparison, all tested devices range from 0.165 (minimum) to 636 (maximum) ms. » 60 % of all devices are better. This means that the measured response time is worse than the average of all tested devices (32.8 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 not detected |  | ||
In comparison: 53 % of all tested devices do not use PWM to dim the display. If PWM was detected, an average of 8719 (minimum: 5 - maximum: 343500) Hz was measured. | |||

Emot
- aningen dyr
- medioker färgrymdstäckning
- tung för en 2-i-1
- skärmen är en aning för mörk
- problem med reflektioner
- klena och obehagliga högtalare
- aningen besvärlig att använda i surfplatteläge på grund av storleken

Vi framhöll Core i7 HDR-varianten av 2018 års modell av X1 Yoga som ett lysande exempel. Vi lovordade dess välbyggda chassi, bra prestanda och tysta drift men hade problem med dess höga pris. För ca 20 000 kronor kan den modellen av X1 Yoga vara över många användares prisnivå. För 5 000 kronor mindre är Core i5 FHD-modellen bättre för budgeten samtidigt som den behåller dom flesta trevligheterna som finns hos den dyrare modellen.
Prestandaskillnaden mellan Core i5-8250U och Core i7-8550U är försumbar. På så sätt kommer användaren inte märka någon nämnvärd skillnad genom att byta ner CPU:n. Snarare än att investera i en aningen snabbare processor så borde intresserade köpare lägga pengarna på HDR WQHD-skärmen, som kostar runt 1 500 kronor mer. Den dyrare panelen dubblerar ljusstyrkan och har en nästan omatchad kontrast och färgåtergivning. Den bästa konfigurationen som finns är en kombination av Core i5-8250U och WQHD HDR-skärmen.
Core i5-varianten av X1 Yoga behåller dom bästa delarna från sitt dyrare syskon samtidigt som den håller kostnaden nere. För 5 000 kronor mindre erbjuder Core i5 FHD X1 Yoga likvärdig prestanda insvept i samma utmärkta chassi. Om du letar efter en omvandlingsbar i företagsklass och kan tänka dig avstå en ökning på 5% i prestanda i utbyte mot HDR-skärmen så är det här maskinen att skaffa.
