我自己没有尝试过，但是如果你回顾这篇文章，它会谈到改变输出偏好：

在第1组中我看到了这个列出：

HDMI_CEA_VGA = 1，

和第2组：

HDMI_DMT_VGA_60 = 0x4，/ * *< 640x480（60Hz与上述CEA中的VGA相同）* /

您可以尝试这些，看看它们是否提供了VGA信号所需的功能。

Hi everyone,

is there a chance to get an analog signal over the HDMI output so i can convert over DVI to VGA?

Thanks!

I haven't tried it myself, but if you review this article it talks about ways to change the output preference:

In group 1 I see this listed:

HDMI_CEA_VGA = 1,

and in Group 2:

HDMI_DMT_VGA_60 = 0x4, /**<640x480 (60Hz is same as VGA in CEA above) */

You might try those to see if they provide what you need for a VGA signal.
