我们有一些第四代英特尔 NUC我们在其中放置了 SSD 并连接了两个这些平面电视.每台机器都运行Windows 8.1。

我们遇到的问题是，当我们的软件触发受控重启（PowerShell Restart-Computercmdlet）时，偶尔其中一个显示器会变黑。这似乎总是辅助显示器。如果我们继续重启机器，电视就不会恢复。关闭电视电源似乎没有任何作用。

目前，我们有 8 台平面显示器与 4 台英特尔 NUC 进行对比。这种情况何时发生尚无定论。有时发生，有时不发生。它也与任何特定的 NUC 或平面电视无关。

我们尝试更换插入 HDMI / DisplayPort 输入的显示器，然后重启机器。一切恢复正常，但可以肯定的是，一段时间后重启后显示器会再次变黑。更换新的 HDMI 和/或 DisplayPort 电缆并不能解决问题。

如果我们尝试通过 VNC 连接显示黑屏的机器，我们可以在 VNC 中看到两个显示器，但物理显示器上什么都没有。如果我们注销当前登录的用户并重新登录，显示器将开始显示应该在那里的任何内容。

总结一下：

辅助显示器变黑，在经过不确定次数的重启后不显示任何输出。
有些机器已经坏了周不表现出这种行为，然后每隔几天表现出来，然后停止这样做几个星期。
黑屏后，无论重启多少次都无法修复
VNC 通过其虚拟化显示适配器显示两个显示器
注销当前登录的用户并重新登录似乎可以解决问题
故障率和所插的电视机型号之间没有相关性。
故障率与电视是否插入 HDMI 或 DisplayPort 之间没有相关性
在我们的软件中，我们检测显示器的数量，并可以实际看到二监视器已插入。

有什么想法吗？

事件日志分析

我对这台机器运行了事件日志查询，结果发现许多事件称司机发生了撞车事故。

脚本如下：

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

输出如下：
