| The screen shows good response rates in our tests, but may be too slow for competitive gamers. In comparison, all tested devices range from 0.1 (minimum) to 240 (maximum) ms. » 37 % of all devices are better. This means that the measured response time is similar to the average of all tested devices (21.5 ms). | ||

| The screen shows very fast response rates in our tests and should be very well suited for fast-paced gaming. In comparison, all tested devices range from 0.2 (minimum) to 636 (maximum) ms. » 10 % of all devices are better. This means that the measured response time is better than the average of all tested devices (33.7 ms). | ||
Screen Flickering / PWM (Pulse-Width Modulation)
| Screen flickering / PWM detected | 250 Hz | ≤ 100 % brightness setting |  |
The display backlight flickers at 250 Hz (worst case, e.g., utilizing PWM) Flickering detected at a brightness setting of 100 % and below. There should be no flickering or PWM above this brightness setting. The frequency of 250 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 17900 (minimum: 5 - maximum: 3846000) Hz was measured. | |||

Os potenciais compradores com bastante dinheiro dificilmente errarão com o Samsung Galaxy Book 12 LTE, se eles gostam da ideia de um teclado que pode se conectar e da alta portabilidade. Além da escassa seleção de portas, a Samsung realmente conseguiu combinar o melhor dos dois mundos em um único aparelho.
O S-Pen e a capa de teclado ambos são incluídos no pacote de entrega e se desempenham tão bem quanto o tablet bem projetado e perfeitamente construído.
Embora a tela Super-AMOLED não seja perfeita, pode ser vista como o único ponto de venda no novo conversível da Samsung com o seu ótimo valor de preto e alto contraste. Nossa unidade de teste foi um dispositivo LTE e cumpriu todos os requisitos de portabilidade, incluindo GPS / GLONASS, TPM, BitLocker no Windows 10 Pro e ótima duração da bateria. Os usuários de escritório e de negócios estarão encantados com o posicionamento flexível e bons dispositivos de entrada, enquanto a qualidade das câmeras é mais do que um pouco de extra agradável.
O fato da Samsung ter escolhido um sistema de resfriamento silencioso e temperaturas aceitáveis da carcaça em relação ao desempenho total sob carga contínua não deve ser notável enquanto o dispositivo for usado para o propósito pretendido - como um aparelho de escritório. Portanto, definitivamente recomendamos este dispositivo para compra.
