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. » 75 % 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)
Screen flickering / PWM detected | 1000 Hz | ≤ 90 % brightness setting | |
The display backlight flickers at 1000 Hz (worst case, e.g., utilizing PWM) Flickering detected at a brightness setting of 90 % and below. There should be no flickering or PWM above this brightness setting. The frequency of 1000 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 8705 (minimum: 5 - maximum: 343500) Hz was measured. |

Dell Latitude 12 E5270 är en bärbar dator för företag med många säkerhetsfunktioner, vilket ofta är avgörande för inköp. De nya Skylake-processorerna ökar prestandan något jämfört med tidigare generationer. Batteriets livslängd har också förbättrats tack vare ett något större batteri. Priset är dessvärre högt, även om datorn är oklanderligt byggd och är styv.
Gränssnitten är förnuftigt placerade och kan utökas med en dockningsstation. Många köpare har kommit att uppskatta sådana små detaljer och är beredda att betala för dem.
Ett bra första intryck försämras tyvärr av panelens ganska dåliga kvalitet. Skärmen är inaktuell och hör definitivt inte hemma i en företagsmaskin i den här prisklassen, även om det går att uppgradera mot en merkostnad. Panelens låga ljusstyrka försvårar arbete ljusa miljöer kraftigt. Vi hade också uppskattat en snabb SSD som lagringssystem. SSD-priserna har sjunkit drastiskt den senaste tiden jämfört med konventionella hårddiskar.
Vi gillar också det enkla, tunna men ändå styva chassit. Prestandan med Intels Core i5-6300U är definitivt tillräcklig för rutinuppgifter. Pekplatta och tangentbord håller hög klass. Det senare är också begåvat med användbar bakgrundsbelysning i två ljusstyrkenivåer.
