DP接口无法连接显示器的解决办法

AOC的显示器之前一直可以用miniDP转DP的线连接MacBookPro，突然有一天就连不上了。 尝试了重现插拔、重启电脑、关闭/打开显示器，都不行。所以怀疑是线的问题，买了一根新的线，结果还是不行。尝试了HDMI线连接是没问题的。

在准备联系显示器维修之前发现了这个网页 https://zhuanlan.zhihu.com/p/466826180，没想到的是在拔掉显示器电源线再插回去之后，竟然就好了。。。

My AOC monitor, which used to connect to my MacBook Pro with a miniDP-to-DP cable, suddenly stopped working one day.

I tried re-plugging the cable, restarting my computer, and turning the monitor off and on, but nothing worked. So I suspected it might be the cable’s fault and bought a new one, but it still didn’t work. I tried connecting with an HDMI cable and it worked fine.

Before I was about to contact the monitor repair service, I found this webpage: https://zhuanlan.zhihu.com/p/466826180. Surprisingly, after unplugging the monitor’s power cord and plugging it back in, it worked again…
