StarTech.com - HDMI to VGA Video Converter - Black

Nice box, big price at best buy, but absolutely no instructions in the box, the provider assumes that we are all computer savvy, video works great, but what do I connect to the 3.5mm ?? and what gets connected to what appears to be a phone usb connection. a little piece of paper in the box would help a lot, or, print needs and requirements on the side of the box. This web site does not describe any direction either(not readily seen) Sorry not a smoke test kind of guy. Thanks for any effort in providing a solution.

Just bought this adapter to be able to connect my Raspberry Pi 3 to an Acer VGA monitor. First attempts brought no success without external power. After plugging in my cellular charger Rpi screen shown up for about 2 secs then display went black. The same happened when I connected the monitor to my decent MacBook Pro laptop. Now I'm stuck and don't know where to go now without proper documentation. Would it be possible that external power is not enough?

I have tested this adaptor with a different combination of computers, monitors and projectors without any big issues. The adapter comes in a small box the size of a cell phone but the thickness of two. The box is very difficult to open and the adapter sits in a flimsy tray within the box. The packaging was all wrecked removing the adaptor for the first time. The adapter has a VGA port on one side and the other side has a 3.5mm audio port, HDMI cable and Micro USB-B port. The adaptor says that is doesn't require any power so I am unsure why it has a USB port on. There are no included instructions in the box, on the box or on the web site to provide more information. When I first connected this adaptor to my computer I was shocked how quickly it was working. If I connected the HDMI port first to my computer then almost instantly of connecting a monitor the video and sounds were working. If I connect the VGA cable first, then audio and video start within 3 to 4 seconds as does any normal HDMI monitor. The sound and picture from this dongle were crisp, clear and without any delay. When I first played copy protected content (i.e. Netflix) the dongle stopped working and I had to disconnect then reconnect and it started working again. I have not been able to reproduce this issue since but I thought it would be worth noting. This adaptor starts working very quickly. I had doubts about converting HDMI to analog but my mind has been changed since using this adaptor. I received this product in exchange for an unbiased review.

Just received this today, as soon as I plug it onto my mac book pro, the laptop screen starts flashing, indicating it is receiving signals from the external monitor but also losing it all the time. Changed several VGA cables but no difference. Changed to apple mini DP to VGA adapter and that works fine.

Plug right into my HP laptop and it work right off the bat. Connected it to my console switch and now I can switch between my two desktops and the laptop.
