Temos algumas máquinas Intel NUC de quarta geração que colocamos um SSD dentro de e anexou dois de estas TVs planas . Cada máquina está executando o Windows 8.1.
O problema que estamos enfrentando é que, quando nosso software aciona uma reinicialização controlada (o cmdlet Restart-Computer
do PowerShell), ocasionalmente um dos visores fica preto. Isso sempre parece ser o monitor secundário. Se continuarmos reiniciando a máquina, a TV não volta a funcionar. O ciclo de energia da TV parece não fazer nada.
Neste momento, temos 8 dos monitores planares em execução contra 4 dos Intel NUCs. Não há um padrão sobre quando isso acontecerá. Em alguns dias acontece, outros não. Também não está correlacionado com nenhum NUC ou Planar TV específico.
Nós tentamos trocar a tela que está conectada para as entradas HDMI / DisplayPort e reinicializar a máquina. Ele volta bem, mas com certeza, algum tempo depois, a tela ficará preta novamente após a reinicialização. Trocar o cabo HDMI e / ou DisplayPort por um novo não faz nada para resolver o problema.
Se tentarmos o VNCing na máquina que está mostrando uma tela preta, poderemos ver as duas telas dentro do VNC, mas nada na tela física. Se sairmos do usuário logado e fizermos login novamente, a tela começará a mostrar o conteúdo que deveria estar lá.
Para resumir:
Alguma opinião?
Eu executei uma consulta de log de eventos contra a máquina e vi literalmente dúzias de eventos dizendo que o driver falhou.
Aqui está o script:
Get-WinEvent '
-ComputerName "Frobnitz" '
-Credential "localhost\Administrator" '
-LogName "System" '
-FilterXPath "*[System[Provider[@Name='Display']]]" '
| ? {
($_.TimeCreated.TimeOfDay.Hours -ge 3) -and '
($_.TimeCreated.TimeOfDay.Hours -le 9)
} | Select TimeCreated,Message | ft -AutoSize
E aqui está a saída:
