OSMC HDMI to VGA not working

Help and Support
1

I have the following version of OSMC[1] installed on Raspberry Pi 1 model B. My SD card is 4 GB. The display from my Raspberry PI works fine if I use a HDMI cable to connect to a monitor. The problem is there is no display when I use a HDMI2VGA [2] converter to connect to my monitor. I know that the converter works fine as when I connect it to my HDMI out of my laptop. My laptop screen appears fine on the monitor. Now my concern is why Raspberry Pi does not send video over my HDMI2VGA converter ? I have tried the following changes to config.txt [3] however with no progress :frowning:

I don’t know what sort of VGA monitor/TV you’re connecting to, but I find such a device (I have 4 in common use) works fine - without any special config lines to determine mode of operation.
The only precaution I take is to have the monitor connect and on before booting.

I have a similar setup (RPi1B) but with DVI in my bedroom. I use a PC monitor (Dell 23") which has a DVI port and a VGA port. I have attached a DVI to HDMI-male to it and it works flawlessly.

Note I have never connected the RPi1/OSMC installation in any other way. After installing OSMC on the SD, I booted with the monitor attached. Perhaps your RPi1 was previously working with a different screen?

I have LG FLATRON E2260.

I have read that HDMI to DVI is passive connector, So I guess I shouldn’t end up in problem there. Any way I don’t want to sit up on a dead adapter once again :frowning:

There is no way HDMI to VGA can be a passive adaptor - HDMI is digital only (unlike DVI-I which carries both digital and analogue signals) and VGA is analogue.

The adaptor must run off the (very limited) power available on the HDMI port. Are you connecting all the cables and turning on the monitor first before powering on the Pi ?

One of my monitors is a very similar LG Flatron, and is connected via DVI (successfully) - perhaps that is the way to go in this case

According to the specs your monitor has DVI !

Why o why would you do what you are trying to do??
It does not make sense at all. If you have no HDMI but do have DVI and VGA, why would you go for VGA? What is the reason behind that?

Agreed, a passive HDMI to DVI cable is the way to go. You won’t get sound across DVI but you wouldn’t over VGA either. You can still use the analogue audio output when using an HDMI to DVI cable.

Yeah I agree LG FLATRON E2260 does have DVI, HDMI and VGA, however, that is my main monitor for a dedicated CPU. However I have another monitor which has just DVI and VGA to which my Raspberry PI is connected to with the help of a HDMI to VGA converter. I was working fine up until a month ago when my adapter failed and when I tried to get a similar one it no longer works with it.

I am currently planning on getting this

Let’s hope that this one works - I feel I may have one stashed away, but cannot remember if it worked.
As an added note, my flatron screen is shared between a Win7 PC and n RPi system using a KVM whivh switches DVI
This, however, gave me troubling with mouse sharing.
Good luck
