The Raspberry Pi single-board computer has always had an HDMI port for connecting a display. But it doesn’t have a VGA port so if your monitor only supports VGA input you’ve needed to buy an adapter that converts signals from digital to analog.
You can use the adapter to connect a VGA monitor… and soon you may even be able to use both the VGA adapter and the HDMI port to connect two displays at once.
There are a few caveats. First, the software for supporting dual displays is still a work in progress and might not be available for a few more weeks.
Second, and more importantly, you can’t actually by one of these new VGA adapters yet. The designs are hosted at GitHub and anyone could build one themselves, but you’ll need a custom printed circuit board which can be expensive to produce unless you place a large order.
If there’s enough demand for this product, I suspect we’ll see someone mass produce a VGA adapter in the future. For now you find more details in the video below.
