我需要使用电脑上的 Miracast 功能,将电脑屏幕用作笔记本电脑屏幕的扩展
电脑信息:
OS : Windows 10 Pro 22H2 build 19045.2486
Motherboard : P8H61-M LX3 R2.0
Chipset : H61
Video card : ATI Radeon HD 4600 series WDDM 1.1
Processor : Intel i5 3330
Intel Hd Graphics: 2500 WDDM 1.3
Monitor : Dell U2312HM
DirectX Version : DirectX 12
根据英特尔网站,H61 芯片组、HD Graphics 2500 和 ATI Radeon HD 4600 显卡与 Miracast 兼容。我无法获得有关戴尔 U2312HM 显示器是否与 Miracast 兼容的信息!
当我在电脑上运行“dxdiag”命令时,Miracast 选项显示为“不可用”。
提示符下执行的命令:
netsh wlan show wirelesscapabilities
:
Interface name: Wi-Fi

Wi-Fi Direct GO : supported

请注意Coletor Miracast
选项说的是Supported
。

注意:
我的电脑有来自wifi路由器的有线连接,并且安装了wifi网卡,也就是说,我既可以通过有线连接,也可以通过wifi网卡访问互联网。
为什么在 dxdiag 命令中 Miracast 显示为Not Avaliable
Dell U2312HM 显示器可能是导致 Miracast 停留的问题Not Avaliable
