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

1020 Hz

≤ 20 % brightness setting

The display backlight flickers at 1020 Hz (worst case, e.g., utilizing PWM) Flickering detected at a brightness setting of 20 % and below. There should be no flickering or PWM above this brightness setting.

The frequency of 1020 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.

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
46.4 ms ... rise ↗ and fall ↘ combined	↗ 28.4 ms rise
46.4 ms ... rise ↗ and fall ↘ combined	↘ 18 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. » 99 % of all devices are better. This means that the measured response time is worse than the average of all tested devices (21 ms).
↔ Response Time 50% Grey to 80% Grey
60 ms ... rise ↗ and fall ↘ combined	↗ 26.8 ms rise
60 ms ... rise ↗ and fall ↘ combined	↘ 33.2 ms fall
The screen shows slow response rates in our tests and will be unsatisfactory for gamers. In comparison, all tested devices range from 0.165 (minimum) to 636 (maximum) ms. » 95 % of all devices are better. This means that the measured response time is worse than the average of all tested devices (32.9 ms).

Emot

- bleeding från bakgrundsbelysningen vid den nedre kanten

- PWM på låga ljusstyrkenivåer

- skärmen behöver kalibreras för bästa prestanda

- SD-läsaren fungerade inte i vårt testexemplar

- dålig placering av SIM-platsen

- dyr

In review: Dell Precision 7720. Test model courtesy of Dell Germany.

Dells Precision 7720 är en väldigt kraftfull mobil arbetsstation. Det högkvalitativa höljet är i princip oförändrat från den tidigare generationen och du får nu en Thunderbolt 3-port som standard. Föregångaren hade fortfarande en del problem med att utnyttja sin fulla potential vid kombinerad belastning på CPU & GPU, men det verkar som att tillverkaren har förbättrat detta. Vårt testexemplar är utrustat med dom allra kraftfullaste komponenterna, men utnyttjandet av prestandan är ändå väldigt bra, även vid extrem belastning. Huruvida du behöver den mängden prestanda är förstås en annan fråga. Särskilt grafikkortet är för många användarfall inte nödvändigt.

Vi blev ganska besvikna på 4K PremierColor-skärmen. Detta är förstås gnäll på en väldigt hög nivå, men vi hade förväntat oss bättre resultat efter leverans för den extra kostnaden. En kalibrering är definitivt rekommenderad för den här enheten. Bakgrundbelysningens bleeding på den undre kanten är också en aning irriterande och skärmen använder PWM på låga ljusstyrkenivåer.

Precision 7720 är ett bra val när du behöver mycket prestanda, då denna mobila arbetsstation faktiskt kan utnyttja hela prestandan hos dom dyra komponenterna.

Det finns inga problem med irriterande fläktar, trots den höga prestandan. Sant, du kan höra dom tydligt vid hög belastning, men dom är ofta avstängda när du utför enklare uppgifter. Vi kan inte riktigt kritisera temperaturutvecklingen heller, och detsamma gäller batteritiden.

Utöver skärmens nackdelar så måste du titta noggrant för att hitta några problem. Listan inkluderar förstås SD-läsaren, som inte fungerade på vår testmodell, men det borde vara en isolerad händelse. SIM-platsen sitter på höljets undersida och är svår att nå, vilket förhindrar ett snabbt byte av datakort i andra länder, till exempel.
