强制永久改变显示器分辨率的正确方法是什么？

我在 Geforce 970 上运行 3 个显示器，设置如下：

  1. Mon1 (1024x768) 连接到 DVI 端口（原始分辨率 1920x1080）
  2. Mon2 (1920x1080) 连接到显示端口
  3. Mon3 (1920x1080) 连接到显示端口

将 Mon1 的分辨率强制为 1920x1080 的正确方法是什么？我需要在 xorg.conf 中覆盖某些内容吗？或者在 nvidia-settings-rc 文件中？

答案1

metamodes在我的特定情况下，我必须在选项中更改分辨率，1920x1080并根据以下内容将行添加Option "IgnoreEDIDChecksum" "DFP-0"到屏幕部分这个答案。
