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 | ||
|---|---|---|
| 15.2 ms ... rise ↗ and fall ↘ combined | ↗ 6.8 ms rise |  |
| ↘ 8.4 ms fall | ||
| 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. » 33 % of all devices are better. This means that the measured response time is better than the average of all tested devices (21 ms). | ||
| ↔ Response Time 50% Grey to 80% Grey | ||
| 32.4 ms ... rise ↗ and fall ↘ combined | ↗ 16.4 ms rise |  |
| ↘ 16 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. » 39 % 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 detected | 26040 Hz | ≤ 50 % brightness setting |  |
The display backlight flickers at 26040 Hz (worst case, e.g., utilizing PWM) Flickering detected at a brightness setting of 50 % and below. There should be no flickering or PWM above this brightness setting. The frequency of 26040 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 8774 (minimum: 5 - maximum: 343500) Hz was measured. | |||

Pro
+ Carcaça robusta
+ Dispositivos de entrada muito confortáveis
+ Conectividade extensa
+ Tela FHD brilhante e colorida de baixa energia
+ Muito bom desempenho do sistema
+ Longa duração da bateria
+ Radeon FreeSync e HDMI 2.0
+ Ventoinha mais silenciosa
+ Mais barato que seu irmão com Intel
Contra
- Sem Thunderbolt 3
- Desempenho da CPU levemente limitado
- Leitor SD de tamanho reduzido
- A carcaça é difícil de abrir
O ThinkPad T495 é o primeiro portátil empresarial equipado com AMD da Lenovo. Ao contrário da série A, ela não vem com um conjunto enorme de compromissos quando comparada aos seus irmãos Intel. A carcaça e a tela são idênticas, exceto pela falta da opção WQHD HDR, e a duração da bateria também está finalmente no mesmo nível.
A única desvantagem real é a falta do Thunderbolt 3 e um desempenho geral da CPU ligeiramente reduzido. Infelizmente, este último parece ser uma restrição artificial imposta pelo fabricante, especialmente considerando que o T490 equipado com Intel pode consumir mais energia. No entanto, o quad-core do T495 permanece poderoso e rápido o suficiente, especialmente para um portátil de escritório.
Excelente tela, bateria de longa duração e bom desempenho. Dado o seu preço mais baixo, o ThinkPad T495 é uma ótima alternativa ao ThinkPad T490 equipado com Intel. A única desvantagem real é a porta Thunderbolt 3 ausente. Se isso é importante para você ou não, depende de como você pretende usá-lo, mas definitivamente não é obrigatório para um portátil de escritório.
Também gostamos muito da tela FHD LowPower. Com seu painel brilhante de alto contraste e sua alta precisão de cores, de fábrica, é muito adequado para edição de fotos no espaço de cores sRGB. Também consideramos o FHD uma resolução suficientemente alta para um painel de 14 polegadas e ajuda a minimizar os problemas de dimensionamento.
No geral, temos que admitir que o ThinkPad T495 é o melhor T490, especialmente considerando seu preço mais baixo.
Observe que recentemente atualizamos nosso sistema de pontuação, Veja mais detalhes aqui. Com o novo sistema de pontuação V7, o ThinkPad T495 obteve 89%. Com o antigo sistema de pontuação V6, ele teria marcado 90%.
