惠普笔记本 amd hd 7450m显卡升级问题

一、惠普笔记本 amd hd 7450m显卡升级问题

1、这个情况很可能是由于AMD显卡命名规则的变化导致的。AMD显卡驱动更新升级到7000系列，比如HD 7450M就是HD 6470M显卡驱动升级之后显示的名称。

2、温馨提示：如果您安装后的显卡驱动不能正常使用，建议您提供一下“这款机器的具体型号”和“操作系统版本”，然后我们为您查询相关驱动供您安装使用。

希望以上回复能够对您有所帮助。

二、戴尔笔记本双显卡驱动问题

1、想要进行双显卡切换，必须同时安装集成显卡驱动和独立显卡驱动，并且按照先集成显卡后独立显卡的步骤进行安装，部分型号的电脑在官网上会直接有双显卡版本的驱动，直接下载该驱动就可以了。

2、建议上戴尔官网来下载驱动，具体步骤：

3、输入戴尔官网网址进入网站，点击顶部的”产品及技术支持“按钮，然后选择”产品支持“下面的”驱动程序和下载“。

4、进入页面后会自动检测当前电脑的型号和需要安装的驱动，把页面下拉，找到显卡驱动，点击进行下载，下载完成后点击进行安装。
