Screen Flickering / PWM (Pulse-Width Modulation)
| Screen flickering / PWM detected | 962 Hz |  | |
| ≤ 99 cd/m² brightness | |||
The display backlight flickers at 962 Hz (worst case, e.g., utilizing PWM) Flickering detected at a brightness setting of 99 cd/m² and below. There should be no flickering or PWM above this brightness setting. The frequency of 962 Hz is quite high, so most users sensitive to PWM should not notice any flickering. Flickering occurs at relatively low brightness settings, so extended use at this brightness setting or lower can cause eyestrain. In comparison: 53 % of all tested devices do not use PWM to dim the display. If PWM was detected, an average of 8774 (minimum: 5 - maximum: 343500) Hz was measured. | |||

Lenovo Yoga Chromebook C630 är ett kraftfullt 4K-monster som det i slutändan visar sig att Chrome OS inte kan tämja. Även om C630 är en av de allra kraftigaste bärbara Chrome OS-baserade datorerna som tillverkats är en majoritet av den kraften överflödig och står i vägen för de aspekter som får Chromebook-modeller att stå ut på marknaden.
I synnerhet är batteritiden dålig jämfört med konkurrenterna och den är långt från vad vi har kommit att förvänta oss från en Chromebook. Dessutom är enheten den kanske minst portabla Chromebook vi testat. Det är priset man får betala för en omvandlingsbar laptop på 15.6 tum. För en familj enheter som marknadsförs åt människor på resande fot blir C630 tung och opraktisk när man släpar den från hemmet till klassrummet till arbetet till caféet.
C630 erbjuder inte tillräckligt för att kunna stå ut på ett meningsfullt sätt jämfört med sina konkurrenter. Pixelbook är inte särskilt mycket dyrare och har de flesta av dessa fördelar i ett kompaktare paket. Dells Inspiron Chromebook 14 har ett aningen mindre fotavtryck och kan för samma pris hålla jämna steg med Yoga Chromebook C630:s prestanda. Inspiron kommer dessutom med en aktiv stylus och har en av de bästa skärmarna som vi har sett på en Chromebook.
Det finns några guldkorn. För det första är 4K-skärmen skarp och vacker. Vidare "framtidssäkrar" de generösa alternativen för RAM och lagring enheten då Chrome OS otvivelaktigt kommer att bli mer krävande i framtiden. Med tanke på framstegen Google har gjort med att bygga in riktig Android och Linux i Chrome OS så dröjer det nog inte länge innan 8 GB RAM är normalt för Chromebook-modeller.
Sammantaget så är Lenovo Yoga Chromebook en kompetent enhet som känns för kraftfull för mjukvaran den kör. Även om en 4K-skärm, 8 GB RAM och en Core i5 CPU är trevliga rutor att bocka av för marknadsföringen så erbjuder de i slutändan inte särskilt mycket mer än andra lyxiga Chromebook-modeller. Som ett resultat av det känns C630 för uppblåst för Chrome OS. Det finns bättre alternativ i det här prisskiktet.
