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 | ||
|---|---|---|
| 30 ms ... rise ↗ and fall ↘ combined | ↗ 17 ms rise |  |
| ↘ 13 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. » 78 % of all devices are better. This means that the measured response time is worse than the average of all tested devices (20.9 ms). | ||

| 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. » 83 % 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 8710 (minimum: 5 - maximum: 343500) Hz was measured. | |||

För
+ tjusig design
+ aluminiumchassi
+ relativt liten och lätt
+ Thunderbolt 3
+ visuellt tilltalande bakgrundsbelysning
+ ljusstark skärm med ett högt kontrastförhållande
+ bra färgrymdstäckning
+ bra SSD
+ relativt tyst, sval och ekonomisk
+ stort batteri, bra batteritid
Emot
- saknar kortläsare
- portarna sitter tätt
- styrplattans knappar låter högt
- skärmen har långsamma responstider
- betydande processorstrypning
- stort tapp i prestanda vid batteridrift
- systemets prestanda är en besvikelse
Omdöme - Bra skärm, dålig prestanda
Läs den fullständiga versionen av den här recensionen på engelska här.
Acers ConceptD marknadsförs som ett högpresterande multimediasystem för kreatörer. Resultatet av vår recension stödjer bara till viss del detta, för Acer har tagit en del genvägar. För över 20.000 kronor får den som inte behöver tänka på priset en tjusig multimedialaptop med en lyx som i ljuset av all funktionalitet ändå är ganska sval och tyst. Dessutom är energiförbrukningen mer än rimlig.
Men det sistnämnda kommer av dåligt presterande komponenter. I synnerhet stryps processorn kraftigt och värmeutvecklingen i det lilla chassit reducerar prestandan ytterligare. Dessutom faller datorkraften ordentligt vid batteridrift.
Den som helt och hållet väljer sitt multimediasystem utifrån hårdvarans egenskaper klarar sig nog bättre med en billigare konkurrent. Men ConceptD har ett äss i rockärmen i form av sin ljusstarka 4K-skärm, som har ett bra kontrastförhållande och riktigt bra färgrymdstäckning. Få andra multimediamaskiner kan tävla på den punkten. Här får man helt enkelt offra det ena eller det andra.
ConceptD 7 är tjusig, tyst, sval och ekonomisk och den känns väldigt lyxig. 4K-skärmen, som har hög färgrymdstäckning, kan vara den avgörande faktorn. Men Acers prestanda är en besvikelse med kraftig CPU-strypning som leder till ett betydligt långsammare system än vad konkurrenterna erbjuder.
