刚刚在工作中得到了一套新设备，包括一台联想 ThinkPad P1 Gen6，配备 Geforce RTX 4600 和一台ThinkPad Thunderbolt 4 扩展坞带有 2 个 1.4 显示端口。为了配合此设置，我有 2 个 LG27UL650 显示器。问题是，当两个显示器都以 60 Hz 的全分辨率运行时，ubuntu 似乎无法显示这两个显示器。Ubuntu 可以检测到两个显示器，但无法显示第二个显示器，除非我将分辨率降低到 2560*1440 或将刷新率降低到 30 Hz。
我正在运行 Ubuntu 22.04.3 LTS。
我的问题与这里的问题类似：双 4k 显示器 - 每次只能使用一个，但两个都可以被发现 但就我而言，扩展坞中的端口应该支持我想要的分辨率/刷新率，并且计算机也应该如此。
我目前正在使用 2 个显示端口进行连接。
