为什么您可能会在显示器上看到无信号消息(No Signal)
显示器上出现无信号(No Signal)问题的原因有多种。下面列出了其中一些：
- 您选择的分辨率超过了您的显示器支持的最大分辨率。
- 您的显示器已打开，但计算机已关闭(Off)。
- 连接显示器和计算机的电缆松动或断开连接。
- 您的显示器有多个输入，而您选择了错误的一个。
- 在显示器和计算机之间建立连接的电缆已损坏。

如果您的计算机已打开并且您检查了电缆和电缆连接，但仍然显示无信号(No Signal)，则您的计算机或显示器工作不正常。您可以通过以下方式检查：
- 将另一台显示器与您的计算机连接。
- 将同一显示器与另一台计算机连接。
4]将您的系统BIOS重置(Reset)为默认值
如果您已尝试上述所有故障排除方法但问题仍未解决，则将系统 BIOS 重置为默认值会有所帮助。
