显示器 eizo efshex785 ,有个 usb-c 接口,接 macbook air m1 的 usb-c 口子,可以很好显示,走的是 DisplayPort Alternate Mode 。

刚刚接 mac mini m4 的所有口子(前二个后三个),显示器都没有信号点亮。

请问,你们有 usb-c 口子显示器吗,试试看能不能点亮? 我不想用 hdmi 啊

搞复杂了,都支持的。你应该不会没插 mini 的电源/没开机吧

大概率是线的问题,MacBook Pro M3 Pro 发布的时候就看到网上说雷雳 4 的口不支持 USB 4 的线连接显示器,必须是雷雳 4 的线才支持 DisplayPort 协议… 而前面的两个是 USB 3 的口,从来就不支持连接显示器… MacBook Air M1 是雷雳/USB 4 口,实际上是雷雳 3/USB 4 ,反而是雷雳 3 和 USB 4 的线都能支持连接显示器…
