我正在尝试使用 HDMI 电缆将三星 6 系列电视用作戴尔 XPS-15 笔记本电脑的辅助显示器。我正在运行 Ubuntu 18.04。
我遇到的情况是,在我的笔记本电脑上,检测到第二个显示器,我可以进入“设置”中“设备”下的“显示”选项卡,看到检测到了三星电气公司 85 英寸的显示器。
然而,在三星电视的显示屏上,我看到没有信号。
当我连接到 LG 电视或戴尔显示器时,没有遇到任何问题。
我曾尝试将三星电视用作同一台笔记本电脑的第二个显示器,但在我的 Windows 分区上(我是双启动),并且我在使用三星电视作为第二个显示器时没有遇到任何问题,这让我认为一定有我可以做的事情让这个设置也可以与 Ubuntu 一起工作。
任何帮助将不胜感激!

我在 askubuntu 页面上找到了这些命令:如何找到我的系统正在使用的视频驱动程序?
再次感谢!

我在三星端找到了解决方案。
设置 → 常规 → 外部设备管理器
可以打开HDMI UHD 色彩设置连接到的 HDMI 端口。打开后,我的笔记本电脑的显示立即出现。问题解决了!
