我尝试使用 HDMI 转 Cat6 延长器将我的第二台显示器连接到我的 PC。该解决方案由一个发射器和接收器单元组成，它们通过 Cat6 电缆连接在一起。然后，每端都使用 HDMI 电缆连接到 PC 和电视。计划将此屏幕放在与我的 PC 不同的房间。
连接好所有设备后，我的操作系统会将屏幕作为 3D 显示器。但是，即使屏幕在显示管理器中可见，它仍处于待机模式。这几乎就像操作系统看到了设备，但无法与其通信一样。
两根 HDMI 电缆都经过测试，发现可以正常工作。已将 cat6 电缆换成已知可以正常工作的电缆。更改分辨率/刷新率没有改善。
我在 ArchLinux 上使用 Gnome 显示管理器，但也在 Windows 7 笔记本电脑上尝试过，结果同样失败。以下是来自 xrandr 的一些信息：

关于我可以尝试什么来实现这一点，您有什么想法吗？如果我可以提供更多信息，请告诉我。
答案1
在与支持人员一起调试情况后，结果发现接收器单元可能已损坏。如果事实并非如此，将更新问题。
