Description: This HDMI to VGA Adapter enables you to connect an HDMI port to a VGA port. These adapters are especially useful for displays or monitors that only use VGA ports so they can be used with HDMI devices like the pcDuino or Raspberry Pi. Each adapter comes with a 3.5mm jack cable for audio output.

Includes:

  • 1x 5' Audio Cable - 3.5mm

  • It works for the raspberry pi. Need to open the config.txt file and uncomment the hdmi. I have an old Dell flat screen monitor looks decent. You can open up the config file on a windows pc and edit it with notepad. Have not tried anything with sound yet.

  • Could we have some data on this please? Supported resolutions would be good, also refresh rates. I’m also very interested in #47110’s / techiebot’s comments below, seems to be a bit of a concern.

    • I don’t believe that comment is referring to this cable, rather in general. We just got in the Beaglebone Black and should have a better idea of what cables can be used with shortly.

  • Can this support HDCP?

    I am having problems hooking up a vga monitor to a BeagleBone Black. I have it working, but the capacitors next to the hdmi port get very hot, then the monitor loses a connection. If I let it cool off, I get an image again at least for a few minutes. Can you tell how you hacked the adapter to add an external power supply? I am thinking that the adapter is drawing too much current and so causing the overheating.

    • You have to open the case, find the place where the wire from the pin 18 of the HDMI connector is attached. That wire carries +5V and is used to power the DAC inside the converter. Unfortunately that pin can’t provide enough current because it is meant to power only a small I2C EEPROM in the monitor that is used for DDC, not a DAC and potentially some extra circuitry. You cut that wire and feed in an external power at that point, one of those ubiquitous USB chargers will do the job fine. The precise mod varies for each of these adapters, there are several types around on eBay and DealExtreme.

  • What about the power requirements for the HDMI->VGA converter? How much current does it try to source from the HDMI port? The power pins on HDMI are meant to supply only some I2C EEPROMs for DDC monitor identification, so they often cannot provide much current.

    E.g. Raspberry Pi can source only few milliamps tops and most such converters either simply don’t work with it or can even fry it. I had to hack a similar adapter to add external power to it to use it with the Raspberry Pi.

  • Just what I need to use my PIs with every monitor I have. That was one of 2 really annoying features of that thing - no VGA and always have to boot from SDRAM. Thanks Sparkfun.
