Screen Flickering / PWM (Pulse-Width Modulation)
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 17373 (minimum: 5 - maximum: 3846000) Hz was measured. |

Artılar
Eksiler
Dell'in Precision 7720 modeli çok güçlü bir çalışma istasyonu. Yüksek kaliteli kasa önceki jenerasyona göre değişmemiş ama artık Thunderbolt 3 bağlantısı da var. Önceki versiyonda yoğun kullanım esnasında hem işlemci hem grafik kartı takılmaları olabiliyordu ancak bu modelde sorun çözülmüş. Test cihazımız en güçlü bileşenlerle geliyor ve sunulan performans yoğun kullanımda bile çok iyi. Böylesi bir performansa ihtiyacınız var mı elbette tartışılır. Grafik kartı özellikle çoğu durum için fazla fazla iyi.
4K PremierColor ekran bizi biraz hayal kırıklığına uğrattı. Bu elbette biraz kulağa su kaçırmak gibi olabilir ama bu kadar yüksek fiyat etiketi olan bir cihazdan daha iyi performans beklemeyi biraz hak olarak görüyoruz. Ekranı mutlaka kalibre etmek gerekli.
Çok fazla performansa ihtiyaç duyuyorsanız Precision 7720 kesinlikle iyi bir seçim.
Yüksek performansa rağmen rahatsız edici fan sesi yok. Elbette çok yoğun çalışırken ses duyabilirsiniz ama basit işlerle uğraşırken genellikle kapalılar. Sıcaklık üretimini de çok eleştiremiyoruz.
Ekranın aksaklıklarının dışında hata bulmak için çok detaylı bakmak gerekli. SD okuyucu da bunlardan biri. Malesef test cihazımızda çalışmadı ama bunun ayrı bir test olduğunu düşünüyoruz. SIM slotu kasanın içinde yer alıyor ve ulaşılması biraz güç.
Tüm bu performans elbette ucuz değil. Ama rakip modeller de benzer fiyatlara satılıyor. Precision 7720 çok iyi bir skorla karşınızda.
