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 | ||
|---|---|---|
| 34 ms ... rise ↗ and fall ↘ combined | ↗ 15 ms rise |   |
| ↘ 19 ms fall | ||
| The screen shows slow response rates in our tests and will be unsatisfactory for gamers. In comparison, all tested devices range from 0.1 (minimum) to 240 (maximum) ms. » 90 % of all devices are better. This means that the measured response time is worse than the average of all tested devices (21 ms). | ||

| The screen shows good response rates in our tests, but may be too slow for competitive gamers. In comparison, all tested devices range from 0.165 (minimum) to 636 (maximum) ms. » 29 % of all devices are better. This means that the measured response time is better than the average of all tested devices (32.9 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 detected | 1000 Hz | ≤ 100 % brightness setting |   |
The display backlight flickers at 1000 Hz (worst case, e.g., utilizing PWM) Flickering detected at a brightness setting of 100 % 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 8774 (minimum: 5 - maximum: 343500) Hz was measured. | |||

Läs originaltestet i sin helhet på engelska här.
Acers Switch Alpha 12 utmanar inte bara med ett lågt pris inklusive tangentbordsdocka, utan också med en genomtänkt helhet och innovativ kylteknik. 12-tummaren har ett välbyggt hölje som kan hävda sig mot konkurrenter som är dubbelt så dyra.
Surfplattan är något för tung för dagligt bruk, men inmatningsenheterna är nästan i nivå med de dyrare modellerna från Microsoft. Skärmen är också imponerande, men mest intressant är den fläktlösa prestandan, med en kraftfull Intel Core i5-processor. Den här lösningen kan möjligen vara framtiden för tunna bärbara datorer och surfplattor. Om Acer även lyckas öka batteritiden och ljudkvaliteten får konkurrenterna det svårt framöver.
Användare som inte kan leva med den korta batteritiden kan titta närmare på alternativ som Lenovos IdeaPad Miix 700 eller HP:s Spectre x2.
