Kısa inceleme: Dell Latitude 7390 2-in-1 (i7-8650U, FHD)

Profesyonel dönüştürülebilir…7390 2si1 arada modeli için konuşulacak çok şey var. Core i7-8650 işlemci, NVMe SSD, sağlam kasa, çift depolama alanı imkanı bunlardan bazıları. Elbette eksileri de var, ancak oldukça pahalı.

Display Response Times

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
30.4 ms ... rise ↗ and fall ↘ combined↗ 16.4 ms rise
↘ 14 ms fall
The screen shows slow response rates in our tests and will be unsatisfactory for gamers.
In comparison, all tested devices range from 0.8 (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 (25.7 ms).
       Response Time 50% Grey to 80% Grey
48.8 ms ... rise ↗ and fall ↘ combined↗ 23.6 ms rise
↘ 25.2 ms fall
The screen shows slow response rates in our tests and will be unsatisfactory for gamers.
In comparison, all tested devices range from 0.9 (minimum) to 636 (maximum) ms. » 82 % of all devices are better.
This means that the measured response time is worse than the average of all tested devices (41.1 ms).

Screen Flickering / PWM (Pulse-Width Modulation)

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 8801 (minimum: 43 - maximum: 142900) Hz was measured.

Latitude 7390 2si1 arada modeli iyi bir yapım kalitesine sahip, hızlı bir sistem sunan ilgi çekici bir cihaz. Bağlantı olanakları, depolama alanı, kolay bakım imkanı gibi harika özellikleri var. Ancak işlemci performansı önceki jenerasyonlara göre sadece biraz daha iyi ve Core i7 seçeneği ne kadar doğru tartışılır. Core i5 versiyonu hem bütçe hem performans açısından daha iyi bir tercih olabilir.

Latitude 7390 2si1 arada modeli iyi düşünülmüş, sağlam ve ilgi çekici bir model. Ancak bazı dezavantajları var ve küçük bir yatırımdan fazlasını gerektiriyor. Dolayısıyla satın almadan önce yüzeyi iyice kazımak gerekli.

Bazı alanlarda soru işaretleri mevcut. Sadece yansıtmalı dokunmatik ekranlar seçilebiliyor, dolayısıyla renk kapsamı etkileyici değil. NVMe SSD, Samsung modelleri kadar iyi değil. Cihaz, boyutu için biraz ağır bunun sebebi de ekran kapağının kalın olması olarak açıklanabilir. Kapak ayrıca çok stabil değil ve durduğu yerde kolayca sallanabilir. Son olarak bir iş cihazının dönüştürülebilir bir model olması ne kadar gerekli tartışmaya açık bir soru. Dell, Latitude 7380 modeli ile aslında ortaya çok daha iyi bir çözüm koymuş ve üstelik yansıtmasız bir ekran seçeneği ile daha hafif ve daha stabil bir model sunuyor.
