HDMI to VGA Adapter

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.

    There are some 'gotchas' that people need to be aware of if they plan to use this adapter with the Raspberry Pi. I learned them the hard way.

    If you boot your Raspberry Pi into NOOBS and you get no display, you have to hit '2' on your keyboard. This will force HDMI safe mode and should get the display to work.

    If you boot your Raspberry Pi in Raspbian you need to edit the /boot/config.txt file. You can SSH into the device to edit the file, even if you don't have a display.

    SSH into the device with the command 'ssh pi@xxx.xxx.xxx.xxx' with password 'raspberry'. Edit the config file with the command 'sudo nano /boot/config.txt'. Do the following:

    Leave this line commented out: htmi_safe

    uncomment these lines: htmi_force_hotplug hdmi_group hdmi_mode

    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.

      I found one on Amazon that works with my RPi as long as i'm using a >750mA power supply. You guys should pull out a pi and test it.

    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.

    Hi guys, I've a problem using this adaptator, the signal has a frequency of 75Hz using Eyefinity , but my projector supports up to 60 Hz. Is there any way to low the frequency down to 60 Hz ? I mean using an adaptator, since it's looked from CCC. Regards
