我正在考虑买一台新显示器。没有插上电源看看会发生什么,我怎么知道我的笔记本电脑是否可以输出 4k 分辨率?有没有我可以运行的命令来告诉我这个?

我想也许我可以 xrandr,但我认为这只会告诉我每台显示器的功能(即使控制器功能更多。)

我还想也许我可以从 中查找设备lspci并在 google 上找到它,但我找不到太多。

我的lspci -v说:

00:02.0 VGA compatible controller: Intel Corporation 3rd Gen Core processor Graphics Controller (rev 09) (prog-if 00 [VGA controller])
    Subsystem: Lenovo Device 500d
    Flags: bus master, fast devsel, latency 0, IRQ 45
    Memory at f3000000 (64-bit, non-prefetchable) [size=4M]
    Memory at d0000000 (64-bit, prefetchable) [size=256M]
    I/O ports at 6000 [size=64]
    Expansion ROM at <unassigned> [disabled]
    Capabilities: <access denied>
    Kernel driver in use: i915

更新:Llama 先生的建议xrandr让我觉得这个输出可能对比我了解更多的人有用。这是我的xrandr:

看起来该xrandr命令可能对您有用。它列出了可用和当前的显示器分辨率。
