我最近收到了一台 30 英寸的 Apple Cinema Display，除了 1200x800 之外，我无法使用任何其他分辨率。我的电脑是台式机，配有 ASUS Strix AMD RX480 和 AMD Ryzen 1800x。
我尝试使用显卡上的 DVI 连接直接连接到显示器，并在两者之间使用 HDMI 适配器。我还进行了更新并尝试通过 Wayland 或 Classic 登录。
这是我的lspci -nn

答案1
xorg 可能不喜欢显示器 EDID 中的其他分辨率，您是否检查过您的 xorg.0.log？当我检查我的 xorg.0.log 时，我发现完整分辨率的模式行被拒绝了。
您可以使用 xrandr 手动将其添加回来，并且可以使用每个帐户的 .xprofile 使更改持久化。
您可以通过读取 xorg.0.log 文件中的 EDID 部分来做到这一点，我的如下所示：

你可以通过打开终端并输入以下命令来尝试模式行：
xrandr --newmode "2560x1600" 268.00 2560 2608 2640 2720 1600 1603 1609 1646 -hsync +vsync
然后使用以下命令将输出更改为新模式：
xrandr --addmode DISPLAY_ID 2560x1600
xrandr --output DISPLAY_ID --mode 2560x1600
其中“DISPLAY_ID”是 xrandr 输出的显示连接名称，例如“HDMI-1”
通过在每个用户的主目录中创建一个名为“.xprofile”的文本文件并添加以下行来设置您的.xprofile：
#! /bin/sh
xrandr --newmode "2560x1600" 268.00 2560 2608 2640 2720 1600 1603 1609 1646 -hsync +vsync
xrandr --addmode DISPLAY_ID 2560x1600
xrandr --output DISPLAY_ID --mode 2560x1600
像测试一样用显示连接名称替换“DISPLAY_ID”。
注意：我在写这篇文章的时候注意到这个问题已经有几年了，但我想我会继续发布答案，因为当我遇到这个问题时我肯定希望找到它。
