Re: VGA/DVI?

Wed Aug 17, 2011 4:08 pm

I read that the Raspberry Pi will have an HDMI port... but what about a normal VGA/DVI? I haven't got a single monitor/television set in my house wich actually has an HDMI port... And it's the same with most people I know. A cheap computer to experiment with is great... but isn't much use if you've got to spend a bunch of money on a monitor/television with an HDMI port. Maybe it's a good idea to make it optional when you order one? I'd rather pay 5 euros more for a VGA/DVI port than having to buy a 200 euro monitor/television.

The board won't have VGA or DVI output as both require additional components and both connectors are physically large. The board does have composite output though, so if your TV or monitor has composite input you are in luck.

You can also get HDMI to DVI-D and composite to Scart converters, so that might be another option.

The "Read before posting" thread (which can be found in my signature) details the outputs the r-pi has. The wiki page is also an amazing resource. Among other things they mention that the r-pi also includes a composite RCA output for TVs/monitors that do not support HDMI. The idea of offering a HDMI->DVI/3.5mm audio for separate purchase is also being tossed around (I hope they do and brand it with their logo ;) ).

Little problem with the forum though, if you search for VGA or DVI you get no results, even though this topic is made and I've also asked the same question in some other topic. So you can't really blame him for asking, because he would not have found the answer by searching for it.

That's why I suggested they look at the "Read before Posting" tread rather than searching for DVI/VGA :P

No! Always read the amazon reviews, those cables DO NOT WORK!

You cannot convert HDMI to VGA without a transcoder (eg the HDFury2). I was actually suckered into buying a VGA-HDMI cable before reading the amazon reviews.

HDMI is the same as DVI-D signalling with the addition of audio during the retrace periods, so you just need a simple cable to connect an HDMI port to a DVI-D device (you won't get sound over that connection, but you should be able to use the 3.5mm analog audio port for that). However, DVI-A and VGA are both analog, so connecting an HDMI port to a DVI-A or VGA device require an active converter.

(@gerits -- the cable you mention is a special case for VGA->HDMI connections where the card can do digital output on the VGA port)

What's a composite port? Never heard of that before...
And how much would an HDMI-to-DVI or composite-to-Scart cost me? I don't think that'll be very cheap either...

Composite Video

It's pretty standard for connecting to TV's. Well at least the old kind.

@RobinJ - HDMI to DVI adapters are pretty cheap, e.g., http://www.dealextreme.com/p/h.....apter-8308 - EUR2.06 - they're entirely passive.

I've got a bad experience with ordering adapters on dealextreme, they never work. Also, my package I ordered at the 19th of april has just been delivered.

You can't use the "Mini changeur HD15 Femelle/Femelle". Wrong type of video!
You just need a cable with at both ends what the English and Americans call 'phone' (And the Dutch call Tulip) plugs:

You plug that in the yellow connector of your TV. That gives you video but no sound. For sound either use headphone or connect the audio out of the Raspi to your TV the read and the white connector. You will need an adapter cable for that.

It's actually a phono plug :P but most people recognize it as an "RCA" cable.
