Please describe your issue below:

Hdmi没有输出，显示器分辨率是2560x1440，能进系统（ssh连接正常），使用了外部供电，线材没问题，以前也有碰到过没显示输出，当时是返厂售后了（换了soc或者加焊），然后好了，但是闲置了一年多，又出现了这个问题，不知道这次是不是还是硬件的问题。

Hello @ping26

你这个log是 4.9内核的吧？可以用 5.15内核提供下完整的内核log吗？同时也提供下如下信息：

Hello @ping26

看log没有看出啥异常，你有试过其他 1080P@60或4K@60 的显示器么？

用一个1080p的便携屏试过，也是没显示
