I can't afford a HDTV, LCD or HDMI, I want to use my VGA monitor, is there a converter I can buy or anything to connect the RCA video part of the Pi to my VGA monitor? Please help thanks.

Farnell sells a composite to VGA converter, the PRO SIGNAL - RP003 for 81 euro.
For similar prices you can also find HDMI to VGA converter, but you must buy one with an external PSU, cheap converters that try to extract power from the computer do not work with the PI.

At these prices its probably cheaper to find a second hand VGA monitor that also happens to have a DVI-D input (which also works with the PI). But take care DVI-D NOT DVI-A.

Hi,

Don't know if this is same item but I bought this converter on ebay (£15.50 delivered), and it works reasonably well:-

CCTV DVD DVR TV RCA AV S-Video Composite Video input to VGA PC Converter Adapter ( 220898958318 )

Supposedly it also accepts VGA input too, so can be used to share monitor between Rpi & PC - but I've not tried this yet, so can't confirm it works.

Hope this helps

It's worth noting there's no audio port with this device just video conversion only.

I'm using a similar product bought from ebay.com with $15, and works great. Indeed, you lose the hdmi audio, but there is the analog audio left :)

Note that adapters like these who do not come with a power supply, but draw power from the PI may work, for some time, but can indeed damage the PI, as its not designed to power such devices through its HDMI port.
In particular the diode D1, near the port is designed for 200mA (and all power to the adapter runs through it) but these devices easily use double that. The power output on a HDMI port is designed only to power a small EEPROM containing the monitors specifications, and such devices draw a maximum of 50mA only.

There have been several reports from users of these devices that they have had burned out D1 Diodes.
Also using it this way may overload your power supply!

Generally speaking, either modify your PI, and use a PSU that can supply the extra 500mA, or only use adapters that come with their own power supply.

Can anyone confirm whether this device works yet? http://www.ebay.co.uk/itm/1080P-PC-HDMI ... 0929883993

I am considering purchasing it so that I can use my Pi through a VGA monitor. Also I presume that the power issues described above would not be a problem with this device as it has it's own power.

Thanks

This one works a treat - excellent quality, separate PSU and audio output via 3.5mm jack. :D
If it doesn't fit, use a larger hammer, else fit a bigger fuse and 'tune' for maximum smoke :-)
