connector to connect the HDMI port of Beagle board to VGA port of a crt monitor...

Hai,
       We are facing a problem that we like to see the output of the
beagle board on a crt monitor
We searched the net but coulnot find the required
connector, ,Possibly is there as such a HDMI to VGA connector???
        Also We are facing a problem in interfacing the BB with
Philips HDTV which has five HDM ports… Please do make us know about
possible steps to be carried out in this regard,
          Thanking you for your precious time,…
With regards,
Abhilash

The Beagle does not support HDMI. It is only DVI-D. There is no VGA or analog output on Beagle. This is clearly described in the System Reference Manual. There are DVI-D to VGA adapters out here, but they are expensive. You might be better off to purchase a DVI-D equipped monitor than to buy the adapter.

As to the Philips TV, I would search the discussion list to find others with this issue. I know that this has come up before and requires the changing of some settings in SW. The default output is 1024x768, 60Hz.

The adapters that I know of are at http://www.hdfury.com/, but some folks have had problems with them: http://groups.google.com/group/beagleboard/browse_thread/thread/84afe0fbd6cbeb22/fa17c5923a061b1e?lnk=gst&q=hdfury#fa17c5923a061b1e. Best to get a DVI-D monitor.

Please stop saying that.

If I say Beagle supports HDMI, then there are royalties to be paid that we don’t want to have to pay as we do not have an HDMI framer on the board and cannot support full HDMI. I cannot in all good faith lead people to think it is indeed HDMI, especially when we are using an HDMI style connector. If this causes confusion for those who do not understand that fact, then I offer my apologies.

It seems like a wiki page summarizing all this would be useful ...

That would indeed be be helpful. It is explained in the System Reference Manual, but not many people take the time to read that anyway.

Say it doesn't support HDMI audio, which is true. HDMI video is, to
my knowledge, exactly the same as DVI-D.

People seem very confused over what kind of video the board outputs.
Quite a few seem to believe it will not work with an HDMI TV, since
the "not HDMI" message keeps being repeated.

The truth is, the video signal from the board is compatible with both
HDMI and DVI-D (HDMI being nothing but a few additions to DVI-D).
That it doesn't support the *full* HDMI feature set is another matter
entirely.

That would indeed be be helpful. It is explained in the System Reference
Manual, but not many people take the time to read that anyway.

It would also be easier to point to when the issue comes up again, I'd
do it, but I barely understand the issue :slight_smile:

In addition to my previous mail, royalties are payable depending on
what the board does, not what you say it does. If you lied, and said
it supported full HDMI, there would still be no payments required (but
you'd be making a lot of people angry).

I agree with your technical anlaysis.

Now, lets talk about licensing issues. In order to use the term HDMI you must pay a licensing fee. That is the issue I have. If we were using the DVI-D connector, this would not be an issue, but we are not. As the desingger of the board, I have to be very careful in what I say and the impression I give. You of course are free to refer to it an any way you choose.

Instead of relying on the adjective “full”, I prefer not to say that HDMI is supported.

How about saying something like this instead:

  The Beagle board can drive any DVI-D compatible display. This
  includes most flat-panels with DVI or HDMI inputs.

Now that sounds great. I will add that into the next SRM Rev for B7 and for rev C2.

I would however like to have some additional information concerning the timings. I am still seeing traffic that some displays require timings that the current drivers may or may not be able to support. Is there a way we can get a table together on a wiki and keep that updated? I think we also need to have settings that are found to work on a model by model bases as we collect the info from various users…

Thanks!

Very nice wording!
I would suggest to add a disclaimer section like:
The Beagle board can drive any DVI-D compatible display provided the
Beagle is set to a video mode supported by the display. This

includes most flat-panels with DVI or HDMI inputs.

Or make that a separate sentence.
Such a clause avoids that people connect their beagle to their TV
using HDMI and get no video (wich is what happens if you use a board
out-of-the-box).
