HDMI to VGA

Thu Dec 26, 2013 10:56 am

I when I try to use my HDMI to VGA cable on my screen with my pi it never works. I'm wondering whether its either the wrong type of cable or the cable isn't working. I have a HDMI to VGA cable where one end is and HDMI head and the other a VGA head. Also when I tried the same cable out with a laptop it didn't work either. What is the problem?

If you are using a plain cable with no electronics in it, then it will not work. It is designed for some systems that output a VGA compatible signal through the HDMI connector. The Pi does not do this.

You need to use an active converter. They used to be expensive, but there are some cheap ones now that work very well. They may require a separate power supply.

See http://elinux.org/RPi_Screens#RGB_analog.2FVGA and especially http://elinux.org/RPi_Verified_Peripher ... rter_boxes for details and a list of converters that have been found to work.

I use this:

Try to avoid converters that don't have an external power supply.
Make sure you get HDMI- IN to VGA - OUT and not the other way around. Both types are readily available and look very similar. Even some of the sellers are confused with descriptions of one and pictures of the other.
You will need to purchase a standard HDMI cable as well.
Unless specified otherwise my response is based on the latest and fully updated Raspbian Buster w/ Desktop OS.

FWIW, I've been trying out this one: http://www.cpmspectrepi.webspace.virgin ... erter.html (also available thro' amazon) over the last few weeks. So far I've tested it with four different VGA-equipped monitors and a T.V. that has both HDMI and VGA inputs (that's not yet shown on the external webpage above as I've yet to update it). Whilst it can be externally powered (and is supplied with a USB power cable) you do need to have a USB PSU available (or, like I have, one with two outputs - one for the Pi, the other for the converter).

Still running Raspbian Jessie or Stretch on some older Pi's (an A, B1, 2xB2, B+, P2B, 3xP0, P0W, 2xP3A+, P3B+, P3B, B+, and a A+) but Buster on the P4B's. See: https://www.cpmspectrepi.uk/raspberry_pi/raspiidx.htm
