I'm possibly buying a TV from a friend but it apparently does not have a "digital optical" output.

Currently I have PS3 to TV via HDMI, and a digital optical cable from my current TV to my surround sound.

If it get the tv without the digital optical, what will be effected and can I fix this with a different type of cable at all? I'm new to all this stuff. PLEASE HELP.
Cheers.

Why are you connecting the PS3 (HDMI) to the TV and not to the receiver? Receiver not HDMI capable? Not HDMI 1.4 for 3D? At the very least you'll want to connect the PS3(HDMI) to the TV with PS3 (optical) to the receiver.

Thanks for your help, I really have no idea about this stuff at all... So I should connect PS3 to the TV with HDMI and connect the PS3 to the receiver with optical?

What will this change the quality of?

Answer to why is - I don't know, someone else originally hooked it up. The receiver does have a HDMI output yes.

Hi AgentK8, you might get more helpful suggestions and answers if you post back with the brand and model of the receiver or surround sound system.

What model TV do you have? What model receiver do you have? If you're not watching 3D movies through the PS3, then you'll want to connect the PS3 (HDMI) directly to the receiver (bypassing the TV all together). The person who set it up likely didn't have a receiver originally.

Most TVs limit their digital audio outputs to stereo when the source equipment is attached using HDMI. So, if you attach your PS3 to the TV and use the TV's digital output to send audio to the sound system, you'll get stereo while, if you run audio direct to the sound system, you'll get true surround sound. There's no way to know the best way to wire up your system without model numbers of all the gear.

The receiver is a Panasonic SA-BTT755.

It was originally set up as is with the same receiver.

The proposed tv (friend selling and bigger than what I currently have) is a "Uniden".

Then your best connection would be HDMI from the PS3 directly to the receiver so it can play the DD/DTS multi channel surround audio rather than only stereo 2.0 from the TV.

Even if the sound for the TV currently isn't used when using the PS3? It still comes via the receiver - which is connected to the (current/old) tv at the moment with optical... which is why I was concerned about a TV with no optical output socket.

And if it connect the PS3 to the receiver with HDMI, does the PS3 still need to be connected to the TV with a seperate HDMI?

What you guys failed to realize is that his Panasonic SA-BTT755 has no HDMI inputs. Just a single HDMI out which is due to the built in blu ray player.

It has one optical input so he can connect the PS3 directly to the TV with a HDMI cable and use an optical cable for audio from the PS3 to the receiver. He'll probably need to change the audio settings on the PS3.

Setting the PS3 to output video via HDMI to the TV and audio via optical to the PS3 will get you the better quality DD/DTS 5.1 audio rather than only PCM 2.0 from the TV.

Don't know, I don't own a PS3. You can find it in the manual though or one of the thousands of PS3 threads online.

You'll get Dolby Digital 5.1 and DTS from your movies or games instead of what you were getting before.

There are some limitations to optical out on the PS3

Nothing more than 5.1 comes out so the PS3 will automatically downmix anything above that when it uses optical out. I believe that you have to tell the PS3 to enable optical when you use HDMI...

lip sync issues may arise if your TV does ANY type of processing to the video input you may or may not be able to correct for this in your receiver

afrogt is right HDMI to TV, Optical to the receiver

Strong or weak in the end we are all dead
