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 | ||
|---|---|---|
| 28.8 ms ... rise ↗ and fall ↘ combined | ↗ 8.4 ms rise |  |
| ↘ 20.4 ms fall | ||
| The screen shows relatively slow response rates in our tests and may be too slow for gamers. In comparison, all tested devices range from 0.1 (minimum) to 240 (maximum) ms. » 73 % 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 | ||
| 55 ms ... rise ↗ and fall ↘ combined | ↗ 19 ms rise |  |
| ↘ 36 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. » 91 % of all devices are better. This means that the measured response time is worse 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 | 217 Hz | ≤ 40 % brightness setting |  |
The display backlight flickers at 217 Hz (worst case, e.g., utilizing PWM) Flickering detected at a brightness setting of 40 % and below. There should be no flickering or PWM above this brightness setting. The frequency of 217 Hz is relatively low, so sensitive users will likely notice flickering and experience eyestrain at the stated brightness setting and below. 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. | |||

Artılar
+ Sessiz
+ Çeşitli
+ Aktif digitizer dahil
+ İyi sistem performansı
+ İyi dokunmatik ekran
+ Çok hızlı WiFi
+ İyi klavye
Eksiler
- Ekranın stabilitesi
- Yüksek sıcaklıklar, yoğun kullanımda termal tıkanma
- Bir yıl garanti
- Dar renk aralığı
- Ekran yansıtmalı ve daha parlak olabilir
- Ortalama WiFi batarya süresi
- Kötü hoparlörler
- Menteşeler yeterince kuvvetli değil
- Modern arayüzler yok
- Test modeli WWAN için uygun değildi
- PWM
- Pahalı
ThnikPad P40 Yoga bizi tam manasıyla tatmin etmiyor. Daha büyük P50s modeline benzer şekilde birçok modern arayüz gözden çıkarılmış. Bunun sebebi de kasanın yeniden elden geçirilmesi. Kompakt tasarıma ulaşılmak adına büyük bileşenler sisteme dahil edilmemiş.
Test cihazımız bu fiyat aralığında beklemediğimiz bazı aksaklıklara da sahip. Stabilite daha iyi olabilir. Menteşeler yeterli değil. M.2 slotu olmasına rağmen WWAN kullanılamıyor ve garanti sadece 1 yıllık. Yansıtmalı ekran dış mekan kullanımı için çok karanlık ve diper alanlarda da tatmin edemiyor. Cihaz çok sessiz ama bunun karşılığında çok ısınabiliyor ve bu da performansı kısıtlıyor.
P40 Yoga alıcıları elbette olacaktır ama profesyonel bir grafik kartına ihtiyacınız yoksa daha iyi alternatifleriniz mevcut. Ayrıca modern arayüzlerin kullanılmadığını ve bu yüzden potansiyelin daha da düştüğünü söylemek gerekli.
P40 Yoga modelinin avantajı elbette farklı kullanım modları. Ancak ağırlığı ve menteşeler yüzünden bu noktalarda da kısıtlandığını söylememiz gerekli. ThinkPad cihazların en güçlü yanı olan klavye bile bazı problemlere sahip.
ThinkPad P40 Yoga çok özel bir müşteri grubunu hedefliyor. Eğer profesyonel bir grafik kartı ve dönüştürülebilir bir cihaz arıyorsanız P40 Yoga modelinin henüz alternatifi yok. Ama Quadro grafik kartına ihtiyacınız yoksa daha hafif ThinkPad X1 Yoga veya daha ucuz ThinkPad Yoga 460 modellerine bakabilirsiniz.
