我有一个 UGreen Micro HDMI 至 HDMI/VGA 转换器，我用它连接我的外部三星 SyncMaster933，它开箱即可工作。
最近我拔掉了所有插头，并使用适配器的另一端将我的笔记本电脑从 Micro HDMI -> HDMI 连接到另一个外部屏幕（也是三星），它也运行良好。
当我最后一次移除所有东西，将我的笔记本电脑重新连接到 SyncMaster 时，屏幕无法识别。
xrandr -q 已连接到三星 SyncMaster933

我曾尝试使用 xrandr 向 HDMI 添加各种分辨率的模式，但没有效果。
$ xrandr --addmode HDMI-1 1360x768
$ xrandr --output HDMI-1 --mode 1360x768 --right-of eDP-1
