HDMI Tv connection

Hi here is my issue

I added directly an HDMI TV to from my ROku Box to My TV
(Before the new TV it was connected through RCA)

Before The Roku was going trough my AV receiver ONKYO R540.
But this receiver does not have HDMI connector.

So now the picture is better but I have only the TV sound option,

How could I connect my TV trough the receiver, (to be able to use my surround ) ?

Should I use an adaptor ? (but will that affect the image)

Or can I have the TV connected directly to the ROKU via HDMI
And have either the ROKU box or the TV connected to the receiver to get the surround ?

Thank you

Your TV should have a digital out that you can connect to your receiver. That way you can hear (just) stereo directly over your TV speakers or surround using your receiver. Your receiver has a coaxial in for that (input #1). You need a Coaxial digital audio cable for that, not a normal rca cable. You need to assign that digital input as it's default assigned to 'DVD' on your receiver.

>> Does it mean that I can't us my DVD player anymore?
That depends how you did connect your DVD player, how did you connect it? You could for example assign VIDEO 3 to that digital (coax) input and leave the DVD assignment for what it is.

It's the first one, like this one:

You've checked that your TV has a coax digital output, right? If you'r unsure, what brand/type of TV do you have?

HDMI direct to the TV will supply the best possible image for the source media and the media player.

I would only look at the Roku HD if

you have  source media in 1080,
want the option of wired network
have a HDD to plug in directly

There is no difference in audio quality when using a coax digital audio cable or optical cable. This TV apparantly has SPDIF optical and no SPDIF coaxial. You can use VIDEO 1 on your Onkyo, the default assignment is OPT 1 - no need for reassignment in that case.

ok the problem is that I conected the TV Directly to the box via HDMI
But I don't see an improvement in the picture quality.

So I guess to get the only option would be to get the Roku HD ?

Also I only have the option on the TV : 16:9, 4:3, zoom 1, 1zoom 2.

I can't get "Screen fit"

Remember that the problem here could be in source media. What is the specs of the media you are playing because poor quality media files will always look bad on a high def TV and the cabling or media player will not fix this

Recommend that you (test) play an HD stream from YouTube to do a quality check.

We tried to play HD from videos from amazon
but we can't get the pristine resolution

Also I can't choose the option fit screen so the  people don't have the right dimension on the screen

that's from the roku

I don't see any model number on it

Should I upgrade it?
