| 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. » 36 % of all devices are better.

| 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)
| Screen flickering / PWM detected | 21740 Hz | ≤ 20 % brightness setting |  |
The display backlight flickers at 21740 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 21740 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
Contra
Os desktops empresariais, incluindo o todo-em-um, fazem parte de um mercado que é mais fácil de analisar do que o mercado lotado e diverso de portáteis de negócios. Aliás, não há nada particularmente interessante sobre o ThinkCentre M910z (nossa configuração: $1.285), que vai com segurança com um design funcional e discreto e verifica todas as caixas de uma máquina de escritório convencional.
Mas isso não é ruim: de acordo com sua herança, o ThinkCentre faz o trabalho com um design de função sobre formato que oferece recursos tão apreciados quanto a manutenção e atualizações (relativamente) fáceis e um design de suporte de articulação versátil e robusto. Mas também é silencioso (mesmo sob carga), rápido em operação geral, graças à sua CPU quad-core e ao SSD NVMe, e possui um conjunto de alto-falantes que acreditam a reputação tipicamente pobre de seus irmãos empresariais com um bom som na maior parte do espectro (depois de um pouco de ajustes). A tela é um saco misto, graças principalmente a um brilho geral fraco e a uma camada de tela sensível ao toque (que coloca em questão se o comprador deve incomodar com interface de toque quando provavelmente é culpado por essa deficiência), mas pelo menos ela permanece anti refletiva mesmo quando configurado para tocar! Finalmente, o consumo de energia é confortavelmente baixo, então qualquer pessoa que considere a implantação em massa de uma frota de máquinas M910z deve estar tranquilo, pois a conta elétrica não aumentará terrivelmente.
Não há nada particularmente interessante sobre o ThinkCentre M910z, mas isso não é ruim; ele joga com segurança com um design funcional e discreto e verifica todas as caixas de verificação de uma máquina de escritório convencional.
Em última análise, não há grandes pontos negativos associados ao ThinkCentre M910z; é um desktop de negócios capaz que, apesar de não ter um design excitante, abrange todas as suas bases no mercado de negócios e é fácil de manter e implantar que deveria aproveitar o suporte de muitos departamentos de TI.
