The Acer 4930g741g32mn notebook, which was bought earlier, uses an XP system and cannot connect to the projector. Some people say they need to install a driver.
I searched the internet and said it was about to install Acer epresentation management,
Therefore, an Acer epresentation management is downloaded. The system prompts you to install Acer empowering technology framework first,
So I downloaded the two software. Note that they must all be for XP.
It seems that it is difficult to find the XP version on the Internet. In article , we provide some column XP Acer drivers. Here we also share the following:
