安装官方Debian13后经常没有hdmi输出，基本上下电个四五次之后就会没有hdmi输出，这是什么情况
Following our testing, we have been unable to reproduce the issue. Could you kindly provide the complete log captured when hdmi out is unavailable?
If it is convenient for you, we may continue our discussion on the Chinese forum going forward.
By the way, could you please provide the maximum resolution and frame rate of your HDMI monitor.
