Troubleshooting • Re: HDMI alternative

For VGA it's possible to buy/make an inexpensive adapter but it uses all of your GPIO pins. Google gertvga for more.

it is also called vga666 - e.g. https://www.aliexpress.com/w/wholesale-vga666.html

Indeed. And I've also seen them called gertvga666 too.

Anywho...

I've just recalled two more possibilities but have no idea how well they'd perform:

• A USB Displaylink (not displayport) adapter using v1 of their protocol (v2 is difficult or impossible to get working under Linux) which you'll probably only find secondhand.
• A Pi zero running one half of linked to the 3B via USB running the other half. I've a feeling that's not bundled into/with the kernel but I'm not certain about that.

Not sure whether either of those will transfer audio.
