DVI to HDMI and the sound?

Hello,

might be stupid question. I connected my MBP via DVI and HDMI to my TV. There is no sound. I know that HDMI is for sound as well but I know nothing about DVI.What is my problem.

As well the TV shows my wall papaer and as well my photo programm Foto Magico. But it does not show my any other programms (itunes, fire fox etc) on the TV. The mouse is only visible on the TV when I move it out of my MBP screen. What do I do wrong?

Sorry by I just switched from Windows...(for sure a good decission)

Mac Book Pro, Mac OS X (10.5.5)

Ok, you are correct about HDMI having audio, but unfortunately DVI is kind of an older technology. It is analog and does not carry sound. You can either get a separate audio cable to get the sound if your tv allows you to. Or you can just forget about that cord and get a VGA cord with audio and use the DVI-VGA adapter that came with the Computer.

And with the other problem with just certain things coming up on the display. It is doing this because there is a setting that you are missing. When you hook it up, go to System Preferences, and then to display. Click on one of the tabs (can't remember which one) and you need to check on the box that says Mirror. This will fix your problem for this.

And just to give a little advise, when getting cables, buy them from monoprice.com. They have quality products for dirt cheap prices and are very reliable.

Any more questions on this, just ask.

Just a couple of clarifications and additions:

DVI is not analog, hence the name "Digital Visual Interface" (or sometimes "Digital Video Interface"). You are correct that it does not carry audio, as I said above.

VGA (which is analog) would be an option, but many TVs with HDMI do not offer a VGA input. Oliver will need to check to see if his TV has as VGA input; if it does, then it would been an option and may be the only one if his TV will not allow a separate audio input when using the HDMI input. But HDMI/DVI will be the preferable option over VGA, if possible, for best quality.

Regards.

Thanks for the very detailed answers. Quality is for me more important so I will keep the DVI HDMI connection and will find a solution for the sound.

Yes,now the screen on the TV is working proper. As you said I missed to tick off one function. But one question is left. When I had connected my MBP to my 40 inch Bravia, i could watch the pictures in full size from left corner to right corner of the screen. Now after the change, same picture has left and right a frame of round about 5 cm but the resolution on the TV is the highest 1920 X something i forgot.What happened now??

When you switch to mirroring, the external display will then be at the resolution of the internal display, which in a 15" MacBook Pro is 1440 x 900. Your TV may scale that resolution or it may letterbox it, depending on what the TV can do and it's internal settings. Perhaps someone else here has a Bravia and can offer further insight.

It is analog (!!!!)

It is not that old and not analog. And the age is not really the issue. When you make a video interface you pass video. VGA didn't either as the V in VGA means video just like the V in DVI. You may want to recall that invitation if you don't know the right answer.

HDMI the M means multimedia hence the whole integrated audio and video (and copy protection) all in one clever stream.
