装有 LinuxMint 操作系统的笔记本电脑无法检测到外部显示器

我已将其发布在超级用户论坛中,但没有得到任何回复,因此我将其发布在这里。

笔记本电脑:华硕 ROG Strix,G531GT-AL041T,G Core i7 第 9 代,配备 NVIDIA Geforce GTX 1650 显卡。戴尔 22 英寸全高清显示器 (E2218HN) 通过 HDMI 电缆连接。外接显示器在笔记本电脑的默认 Windows 操作系统下运行良好,但在 Linux Mint 19.2 Tina 操作系统下运行不佳。通过 HDMI 电缆未检测到信号。即使在“首选项”->“显示”中,笔记本电脑也无法检测到外接显示器的显示。我还安装了推荐的 nvidia-430 驱动程序。如何让 HDMI 连接的外接显示器工作?请帮忙。以下是一些必需的信息:
