Screen Flickering / PWM (Pulse-Width Modulation)
| Screen flickering / PWM detected | 21000 Hz |  | |
The display backlight flickers at 21000 Hz (worst case, e.g., utilizing PWM) . The frequency of 21000 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 8705 (minimum: 5 - maximum: 343500) Hz was measured. | |||

Pro
Contra
A diferença mais notável entre o antigo Surface Pro 4 e o novo Surface Pro 2017 é a duração melhorada da bateria deste último: mais de 12 em vez de 7 horas em nosso teste Wi-Fi. Nenhum outro concorrente conseguiu chegar perto.
O Core i5-7300U sem ventoinha é capaz de funcionar no máximo desempenho durante rajadas curtas graças ao resfriamento da câmara de vapor. Depois de um curto período de tempo, a CPU começa a se afogar. Os usuários avançados podem estar melhor com o Dell Latitude 12 5285 (i7-7600U, 10% de perda de desempenho em nosso Cinebench loop) ou o IdeaPad Miix 720 (i7-7500U, 9% de perda de desempenho). Embora eles também sofram de afogamentos, não é tão ruim quanto no Surface Pro 2017 (33%)
Isso significa que um dos principais benefícios do Surface Pro 2017 - portátil de desempenho sem ventoinha - desapareceu no ar. O desempenho não é ruim, mas não é permanente. Além disso, não conseguimos verificar o ganho de desempenho de 50% em relação ao seu antecessor imediato, que a Microsoft prometeu. Também não possui USB Type-C e Thunderbolt 3, o que teria feito que o Surface Pro esteja muito mais preparado para o futuro.
No lado positivo, ele tem câmeras decentes que suportam Windows Hello, um microfone muito bom e uma tela brilhante com cobertura sRGB decente. Pode obter tudo isso por $1299. Consideramos que o tablet é muito caro, especialmente porque o preço não inclui nada além do tablet e um carregador.
Alternativas
Os seguintes três tablets vêm à mente ao procurar alternativas ao Surface Pro. Todos os três são impulsionados por SoCs de 15 W SoCs, foram avaliados de forma similar por nós (Dell), e não se afogam tão massivamente quanto o Surface Pro faz, graças a suas ventoinhas. Eles também são mais baratos.
·Dell Latitude 12 5285 2-in-1 (1275 Euros/~$1458, 88%)
·Lenovo IdeaPad Miix 720-12IKB 1 (1145 Euros/~$1309, 85%)
·Asus Transformer 3 Pro T303UA (1100 Euros/~$1258, 86%)
O Latitude 12 possui apenas uma tela FHD, mas é mais brilhante. Todos os três possuem portas USB Type-C, os tablets da Lenovo e da Asus ainda suportam Thunderbolt 3. Infelizmente, o último apenas durou 3:43 horas em nosso teste Wi-Fi e a CPU é incapaz de utilizar todo o seu potencial.
Isso deixa o IdeaPad Miix 720 como a única alternativa real. Apesar das escassas 5:45 horas que durou no nosso teste Wi-Fi, ele também tem os seus pontos fortes: limitou-se a uma perda de apenas 10%, tem um bom teclado com resposta decente e uma ótima tela de 2880x1920.
Caso você realmente não precise da duração da bateria Surface Pro, o Miix 720 e o Transformer 3 Pro oferecem uma melhor razão de preço-desempenho. Afinal, teríamos que adicionar a base do teclado, uma caneta e uma base externa de USB para obter um dispositivo totalmente equipado com mais do que o mínimo de portas.
