HDMI to VGA

Tue Feb 16, 2016 8:40 pm

Hi, my HDMI to VGA adapter isn't working, please help.
This is my adapter http://www.amazon.co.uk/Storite-HDMi-VG ... dmi+to+vga
And using some webpages as a guide, nothing works. I followed all the instructions on this one too: http://thepihut.com/blogs/raspberry-pi- ... ga-adapter , But nothing is working, is this a supported adapter? Or is there anything I'm not doing?
BTW: It's a Raspberry Pi B

If it is an older RPi model B you will likely need one powered


The one you listed is for RPi A+ / B+ / 2B / Zero

Are you sure your HDMI is enabled? Also - are have you tried being plugged in on bootup? I think you cannot plug HDMI in on the fly.

You can if you force HDMI hotplug in config.txt:

Code: Select all

hdmi_force_hotplug=1
On the actual issue...the HDMI to VGA converters that get their power from the Pi may not support all monitor resolutions, plus they may use the current that is supposed to power the chip that responds back with monitor data for their own power, thus not allowing the Pi to get that data. This would require that the resolution be coded into config.txt.

If one really HAS to use a VGA monitor, it is best to use a converter with its own power. However, I find it cheaper to get used monitors that have DVI input than it is to buy even cheap HDMI to VGA converters, let alone good ones. I've gotten suitable 19" 1280x1024 monitors for as little as $5.
