The farnell piview is pretty clearly an active converter that draws it's power from the HDMI port and seems to work fine with the Pi and most monitors (we use them a lot at Manchester raspberry jam). Presumablly they found a converter chip that was low enough power to get away with it.

The RS one looks similar but I don't have personal experiance with it.

Thank You for your help.

I forgot to write in my post that the monitor is a CRT (IBM E74), have you used the Farnell one with CRT monitors at the Manchester raspberry jam ?

As usual a 'newbie' guide is hijacked by geeks. When people need info about specifics they by nature become geeks and it shouldnt be in the newbie section but a seperate thread. If I wasnt already in IT i would be rushing for a multimeter and panicing. Go to the experts page not the novices section.

I haven't hijacked the thread, I asked for a guide to buying, in the thread titled buyers guide.
I am a total newbie to Raspberry Pi , have not purchased one yet as I don't know if I will be able to use it via my monitor until my question has an answer. I am also new to Linux.
Unsure how less I need to know than zero about using the Raspberry Pi or Linux to be classed as a newbie in these areas.
Your response is really quite odd.
Today is my birthday and hopefully I wont be getting a Pi off anyone and have to send it back for a refund, alongside a print out of the community friendliness.
When this monitor has died and the spare and it is time to buy a new montor then I will buy one that suts the Pi if I dont decide to buy alternative instead, and return to the forum no doubt to ask different types of questions.
For now admin please delete this account, thank you.

Hmm. Moderators job to do this sort of thing, when necessary, and all you have done is pee off a beginner...well done. Please be more considerate when posting.

Short answer: no. An active adapter might work depending on operating system and drivers but not a straight adapter cable, sorry.

That is correct, as the first post states
If your monitor only has a VGA Connector, you are out of luck! It is not possible to buy a cheap HDMI->VGA Cable!!! If you see a cable that is VGA on one end and HDMI on the other it will not work. If you want to go from HDMI to VGA you will have to buy a more expensive convertor box, ideally one that uses an external power supply, like this one.
The reason for this is those DVI->VGA adapter only work be cause certain video cards use some of the pins to send the analog VGA signals in addition to the digital DVI signals. The Pi only outputs HDMI (a 100% digital signal) so there's no way to use a passive VGA cable.

If you want to use a VGA connection, your only option is to use an active adapter to convert either the Component (RCA) to VGA or an active adapter to convert the HDMI to VGA. If you convert the component video out you'll get a much lower maximum resolution, but the adapter will be much cheaper. Conversely converting the HDMI will give you a much higher resolution, but will also cost more.
Dear forum: Play nice ;-)

I have bought on and for Composite Yellow works, but after reading several posts have hooked up the Audio on a TV with AV input and like many posters have stated when using cables, the Audio is the wrong way round, so is it the Pi Hardware or the Adaptor which is causing transposed Audio ?

Neither. You're ears are on the wrong sides.

Here's my setup
1. Raspberry Pi Model B+ with Noobs card
2. Pibow case ( Optional, I just like to be gay with the rainbow version (jk) )
3. Wi-Fi Dongle
4. Bluetooth Dongle From Years Ago
5. PS/2 Keyboard And Mouse From Years Ago
6. VGA Monitor from Years Ago
7. PSU & Cable from Months Ago
8. VGA Converter BOX with EXTERNAL POWER SUPPLY
(BTW will a VGA Converter that draws power from HDMI Ports Work? This Box can draw directly from the Pi and I would love to use less power plugs.)
9. Cat 6 Cable That I unplugged from my NAS hours ago
10. Get a HDMI/Composite monitor if possible, if not: DVI-D or SCART, or DVI-I. IDK, might just work. DO NOT GET A VGA MONITOR UNLESS THAT IS AN OLD MONITOR! But seriously, Connecting my Old VGA Monitor to my Raspberry Pi Took HK$170 (Super-Short HDMI Cable, and a converter box that gets external or internal (pi) power.) where buying a new one might cost more than your Pi.

I'm having difficulty in finding GPIO extenders for B+ (40pins). Anyone can provide me a link with a good price/shipping to AU? I'm not having lucky in eBay/Amazon :/

If you have a B+ then it will provide enough current to the HDMI port for cable powered adapters to work, on a B its a bit iffy, but no longer so on a B+

Hello, first time poster here who's just been burned on a bad A/V Cable and is looking for help with a replacement. There's two listed in the first post; http://www.amazon.com/Fosmon-Technology ... B00HND2FW8 and http://www.amazon.com/gp/product/B004UCU72U/ .

Sadly for me, rather than purchasing one of those I made the mistake of purchasing one that stated "Ideal for the new Raspberry Pi Model B+" off of Amazon.com. That particular phrasing couldn't be further from the truth, since the ground is on the closest ring to the base of the connector (checked with a multimeter per suggestions here and elsewhere) and as such it is incapable of outputting any audio or video signal to any of the RCA connections. For sanity's sake I did check to make sure the Pi was actually outputting audio; it works fine through ear-buds, so we know the cable is bad

Knowing this, can anyone confirm that either of the two above will work, hands down? I'm aware the cables may need to be swapped (yellow/red, yellow/white, red/white) and am fine with that, I'm just wary now about being burned on bad cables again, especially as the two listed don't appear to have the tip-ring-ring-sleeve connections posted anywhere to make sure that they're right.

Will be grateful for any assistance I can get in this matter; who knew so much stress could come from a $8 cable :lol:

In this thread on advice purchased this adaptor and yes the Left and Right are switched, but I believe with the latest Firmware this issue has been fixed.

I'm looking to see if that one's on Amazon; eBay and I don't tend to get along since someone cracked my account and tried to make some bogus purchases with it :(

The really annoying this is how few places bother to put the TRRS arrangement public for people who actually know what arrangement they need, particularly since not all these cables are made equal. It's like "Hey, let's make this like rolling dice, where the customer doesn't know if it'll work when they get it. It's like a casino, and people love those right?"

I guess now's a bad time to mention I'm in the US :lol: Thanks for the links in any case; if it gets desperate I know a friend in the UK I can convince to order it and ship it to me, but I imagine shipping costs would be relatively high for what it is.

I've found three cables thus far on Amazon that were nice enough to have the TRRS specs posted; sadly they all have ground on the sleeve. If all else fails I'll snag one of the two posted and we'll cross fingers, because before any of that happens the other one's gunna need to get refunded, so there's still time for the hunt :)

fyi this is the pinout I used: http://www.raspberrypi.org/forums/viewt ... 75#p577977

The pinout arrangement I found earlier, the problem is almost no one on amazon bothers to list what the cable actually uses. Didn't know Kenable had an Amazon store though, which just saved my bacon - if I'm reading http://www.amazon.com/gp/product/B004US2Y2A/ correctly, the pin arrangement is correct (ring 3 on theirs is 2 in the pinout you linked, because they're going with the tip being 1 rather than tip being 4).

I'm looking through to see if they have the exact adapter, but otherwise I think that's gunna be the one I get (and for $4 if it's wrong I won't complain as much, since it's not specifically marketted as being for the Raspberry Pi B+ unlike the [insert your favorite insult of choice here] cable I bought. Thanks much for pointing them out :)

Edit: Bad wording, fixed

Edit Edit: Found it, they have both and they're both the same pinout :) Just have to decide which'll be easier to use with my setup, might go for the one that's a cable rather than an adapter. Double-thanks are in order though, since I'd quite literally have been digging around for a few days trying to find these :)

Edit 3x: Their US store looks to be like 18-26 business days; I'm trying one other I found before trying that mostly as I'm impatient, and the other one I found was marked as a Zune so it should be an exact match. Still incredibly thankful for the digging though, because if this one is bad too then I'm going to grab the other one and wait, cause I hate doing returns over and over. Thanks again folks for tolerating me :)
