Kısa inceleme: LG Gram 15 (i5-8250U, FHD) Laptop

Name: LG Gram 15Z975
Brand: LG

XPS 15 yarısı ağırlığında. 15 inçlik bir notebook ne kadar hafif olabilir? LG Gram 15, 1kgnin biraz üzerindeki ağırlığıyla en hafif cihaz olmayı hedefliyor, ancak bazı ödünler vererek.

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
25.6 ms ... rise ↗ and fall ↘ combined	↗ 14.8 ms rise
25.6 ms ... rise ↗ and fall ↘ combined	↘ 10.8 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. » 58 % 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
35.2 ms ... rise ↗ and fall ↘ combined	↗ 19.6 ms rise
35.2 ms ... rise ↗ and fall ↘ combined	↘ 15.6 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. » 45 % of all devices are better. This means that the measured response time is similar to 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 not detected

In comparison: 53 % of all tested devices do not use PWM to dim the display. If PWM was detected, an average of 8743 (minimum: 5 - maximum: 343500) Hz was measured.

Artılar

+ İyi port seçimi: HDMI, USB-A, USB-C, MicroSD

+ Arttırılabilir RAM ve depolama alanı

+ Dar çerçeve, magnezyum alaşımlı tasarım

+ Keskin IPS ekran, derin kontrast

+ Sessiz sayılabilecek fan

+ Çok hafif

Eksiler

- Yansıtmalı ekran, yüksek çözünürlük seçeneği yok

- Esnek ekran ve temel ünite, kırılgan izlenim

- Thunderbolt 3 yok

- Zayıf hoparlörler ve bass

- Dış mekan kullanımı kötü sayılır

- Turbo Boost performansı güvenilir değil

- Ekran koruması yok

- Klavye tuşları daha iyi olabilir

- Kamera yerleşimi

- SD okuyucu tam boyutlu değil

- Ekran menteşeleri daha sıkı olabilir

- Yavaş şarj

- Harici grafik kartı yok

Dünyanın en ince nootebooku olmak için nasıl ödünler veriliyorsa en hafif olmak için de farklı şeylerden vazgeçmek gerekebiliyor. LG Gram 15 oldukça hafif olabilir ancak çoğu standart Ultrabook cihazda bulunan özelliklerden vazgeçmek gerekebilir.

En büyük eksikliği zayıf kasada görüyoruz. Dar çerçeveli ekran köşeden köşeye parlak bir ekran ile geliyor ve çoğu ultrabooka göre oldukça esnek. Magnezyum alaşım kasa ince görünümü sağlıyor. Ancak sağlamlık konusunda şüpheleri de beraberinde getiriyor.

Performans tarafından bakınca harici grafik kartı olmayışı ve işlemcinin Turbı performansını uzun süre koruyamayışı gibi durumlar söz konusu. Bunun dışında yumuşak klavye, ortalama ekran menteşeleri, karanlık sayılabilicek ekran aydınlatması, kameranın konumu ve Thunderbolt 3 olmayışı gibi durumlar söz konusu. Bu yüzden LG Gram deneyimi daha ağır XPS 15 veya Lenovo Yoga 720 gibi alternatiflere kıyasla daha zayıf.

Elbette pozitif yönler de mevcut. Fan sesi genel olarak duyulmuyor, depolama alanı ve RAM arttırılabiliyor, fiyat olarak diğer iyi bilinen markalardan daha ucuz. Eğer 15 inçlik hafif bir cihaz arıyorsanız Samsung Notebook 9 daha iyi bir alternatif olabilir. Neredeyse aynı hafiflikte olmakla beraber daha parlak ekran ve dış mekan kullanımı öne çıkıyor.
