我有一台联想 ThinkPad T540p 笔记本电脑,配有 Nvidia GeForce 730M 显卡。目前,我无法在通过 VGA 端口连接的第二台 LG 显示器上设置正确的 1920x1080 分辨率。
我已经尝试了一些解决方案1,2但没有结果(导致xrandr --addmode
步骤错误)。
这是 xrandr 输出

我是 Ubuntu 新手,任何想法都将不胜感激,谢谢!
答案1
我尝试了所有可能的解决方案,但只有一种对我有帮助 - 通过 HDMI 电缆连接显示器(最初是 VGA)。我的笔记本没有板载 HDMI,但它有mini display port
,所以我买了miniDisplayPort to HDMI
适配器,现在一切都很好!
