现在市面上你能买到的主板基本上都是没有显示输出的。显示输出的功能要不集成到cpu里了，要不就是dedicated GPU，需要单独买的。
你看到的主板上的显示输出接口只是接口而已。因为CPU的集成显卡没有地方焊输出接口
查了一下，好像真是的，你是对的：
Yes, you absolutely need a separate graphics card (GPU) with a Ryzen 5 4500 because it does not have integrated graphics and cannot produce a video output on its own. Without a dedicated GPU, you will not be able to display an image on your monitor.
Processor type: The Ryzen 5 4500 is a CPU that requires a separate GPU to function.
Integrated graphics: Unlike some other Ryzen processors (such as the Ryzen 5 4600G or the Ryzen 7000 and 8000 series), the 4500 model lacks a built-in graphics processor.
Functionality: The processor can be part of a working computer, but a graphics card is essential for a video signal to be sent to a monitor.
