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
38 ms ... rise ↗ and fall ↘ combined	↗ 22.8 ms rise
38 ms ... rise ↗ and fall ↘ combined	↘ 15.2 ms fall
The screen shows slow response rates in our tests and will be unsatisfactory for gamers. In comparison, all tested devices range from 0.1 (minimum) to 240 (maximum) ms. » 95 % of all devices are better. This means that the measured response time is worse than the average of all tested devices (21.5 ms).
↔ Response Time 50% Grey to 80% Grey
56 ms ... rise ↗ and fall ↘ combined	↗ 31.6 ms rise
56 ms ... rise ↗ and fall ↘ combined	↘ 24.4 ms fall
The screen shows slow response rates in our tests and will be unsatisfactory for gamers. In comparison, all tested devices range from 0.2 (minimum) to 636 (maximum) ms. » 91 % of all devices are better. This means that the measured response time is worse than the average of all tested devices (33.7 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

1667 Hz

≤ 24 % brightness setting

The display backlight flickers at 1667 Hz (worst case, e.g., utilizing PWM) Flickering detected at a brightness setting of 24 % and below. There should be no flickering or PWM above this brightness setting.

The frequency of 1667 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 17900 (minimum: 5 - maximum: 3846000) Hz was measured.

Recension av: Dell Latitude 7400 2-in-1. Recensionsex från Dell US.

Läs den fullständiga versionen av den här recensionen på engelska här.

Dell Latitude 7400 2-in-1 (28.000 kronor för testmodellen) är ett omfattande steg mot en ny designfilosofi för Dells omvandlingsbara företagsdatorer. Låt oss börja med fördelarna: det går att argumentera för att det här är den snyggaste Latitude-modellen hittills, med ett tjusigt hölje av borstat aluminium, expermässigt CNC-avfasade kanter och hörnen samt supertunn infattning. Den skulle lätt kunna misstas för något ur XPS-serien.

Men genom sin förvandling försöker Latitude att hålla kvar vid många av de praktiska företagsmässiga egenskaperna som så länge har varit seriens nyckel till framgång: enkelt underhåll, hållbar konstruktion, lång batteritid, tyst drift och högkvalitativa inmatningsenheter. Portutbudet har tagit viss skada där USB Typ C/Thunderbolt 3-laddningsportar har lagts till och Ethernet-porten har försvunnit, men för det mesta bör en genomsnittlig kontorsarbetare ha mer än det som behövs. Ljudet har förbättrats kraftigt jämfört med tidigare Latitude-maskiner. Och slutligen har vår enhet på 78 Wh fantastisk batteritid som lätt håller en hel arbetsdag utan att någon laddare behövs.

Latitude 7400 2-in-1 är en ambitiös revidering på en marknad där konservativ och stegvis förändring är den vanliga filosofin. På en del sätt är den en frisk fläkt av (varm!) luft, men den är inte utan brister.

Även om den ser bra ut och känns bra att ta i är resultaten i det här fallet inte bara positiva. Skärmen, även om den är tilltalande i inomhusmiljö, lider av svag ljusstyrka och är kraftigt reflekterande, vilket gör den opraktisk och ibland till och med omöjlig att använda utomhus. Även om övergången till en styrplatta i glas är trevlig så kommer en del företagskunder sörja bytet från separata fysiska knappar till en inbyggd "klickpad"-design. Systemets RAM är nu helt fastlött på moderkortet, vilket innebär att uppgraderingar och byten inte är möjligt (även om M.2 NVMe SSD-enheten fortfarande går att byta ut).

Men det tillkortakommande som står ut mest på vår recensionsenhet är dess förkärlek för höga interna chipptemperaturer, som lätt överväldigar det undermåliga kylsystemet och resulterar i brännheta punkter på höljet och en risk för reducerad CPU-prestanda. Det får en att undra över huruvida det egentligen är praktiskt att trycka in en hungrig och varm Core i7 Whiskey Lake SoC i ett såpass litet hölje med ett konservativt inställt kylsystem.

Vi hade gärna bytt lite högre fläktljud mot bättre ihållande prestanda och lägre temperaturer på höljet, vilket som tur är till viss del går att uppnå genom att byta till Ultra Performance-profilen i Dell Power Manager — detta resulterar åtminstone i en aning förbättrade resultat för ihållande prestanda i vårt Cinebench R15 loop-test (förhoppningsvis kommer en mjukvaruuppdatering göra det steget, som den genomsnittlige oinformerade användaren troligen inte kommer att ta, onödigt). Oavsett så anser vi att det är rimligare att spara pengarna och investera i en konfiguration med en billigare Core i5 CPU, där temperaturerna säkerligen kommer att vara lägre och du slipper betala för en prestandaökning som i bästa fall är marginell.

Topprankade konkurrenter inkluderar HP EliteBook x360 1040 G5 och Lenovo ThinkPad X1 Yoga. Asus Zenbook Flip 14 finns också att tillgå, men den klarade sig inte lika bra som de tidigare nämnda maskinerna i våra tester. Alternativt kan du vänta och se ifall Dell reviderar mjukvaran på 7400 2-in-1 för att åtgärda problemen. Det är på många sätt en utmärkt maskin — bara en aning för ambitiös för sitt kylsystem.
