| 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. » 68 % of all devices are better.

| 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. » 46 % of all devices are better. This means that the measured response time is similar to the average of all tested devices (32.8 ms). | ||
Screen Flickering / PWM (Pulse-Width Modulation)
| Screen flickering / PWM detected | 198.4 Hz | ≤ 99 % brightness setting |  |
The display backlight flickers at 198.4 Hz (worst case, e.g., utilizing PWM) Flickering detected at a brightness setting of 99 % and below. There should be no flickering or PWM above this brightness setting. The frequency of 198.4 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 8719 (minimum: 5 - maximum: 343500) Hz was measured. | |||

Dom bästa aspekterna av Miix 520 är dess processorprestanda, SSD-prestanda, mångsidighet när det gäller portar och priset. Dess prestanda-per-krona är bland dom bästa på marknaden för tillfället då dom flesta andra Windows-surfplattor fortfarande är fast med Core Y eller alternativ från 7:e generationen. Användare som kan utnyttja den extra processorkraften kommer upptäcka att Miix 520 är en lämplig fejk-Ultrabook för resor.
I övrigt är det mesta hos Lenovos löstagbara inte nödvändigtvis dåligt eller ens medelmåttigt, men det finns definitivt rum för förbättring vid jämförelse med några närbelägna alternativ. Surface Pro och Elite x2 har mer robust design, skärmar som är ljusstarkare och har högre upplösning, mer exakta färger och längre batteritid. HP-surfplattan i synnerhet bär också Thunderbolt 3 för ett ännu bredare utbud av anslutningsmöjligheter. En stadigare tangentbordsbas för Lenovo hade också förbättrat den svampiga skrivupplevelsen vid jämförelse med tangentborden hos dom flesta Ultrabook-modeller.
Den tydligaste nackdelen med den snabbare processorprestandan är fläktljudet. Fläkten är aningen mer högljudd än hos Surface Pro och kommer variera mycket oftare under dagligt arbete. Den är inte i närheten så högljudd som hos HP:s omvandlingsbara Spectre-serie, men det är ändå tydligt, särskilt för att vara en surfplatte-modell.
Miix 520 är ett bra köp så länge användaren är medveten om dess nackdelar. Den snabbare CPU-prestandan kommer på bekostnad av högre och mer frekvent oljud från fläkten. Vi hoppas att framtida revisioner uppdaterar skärmen och lägger till Thunderbolt 3 för att göra Miix-serien ännu mer konkurrenskraftig gentemot Microsoft.
