1080p

[SNAKE]

Hi,
new to site,i hope its ok to ask this in this particular category but iam going to buy a new receiver and wonder if i should drop the dough for 1080 p?Can a really good picture be had with component on H/D? or is this HDMI cables more for conveinance?


Thanks

1080p is no go on component, sorry just DVI and HDMI.

What are your intentions of use of 1080p? HD DVD? standard DVD? Cable TV?

HD DVD is the only medium right now with true 1080p. Cable TV is 760p/1080i and standard DVD is 480i.

Isn't Blu-Ray also true 1080p?

I'm assuming MTRYCRAFTS means high def DVD's, not specifically 'HD-DVD' that have true 1080p

Receiver features

Snake,
HDMI is more convenient in that it carries the audio and video signals. You can still take advantage of 1080P over HDMI by connecting the source (BluRay, HD-DVD, etc.) directly to the 1080P display. You would need a seperate digital optical or coax connection to carry the audio signal to the receiver.

If your receiver budget is <$500, I would consider a quality receiver without HDMI like the Yamaha RX-V659, or maybe a refurbished model w/ HDMI (RX-V1600 on Ubid.).

If you are willing to pay $1k or more, the mid-fi models from Yamaha, Denon, and Pioneer all have plenty of audio and video features. In the next 6 months, you will start to see new models which include HDMI 1.3

Component video cables are perfectly capable of carrying 1080p. Most 'good' component video cables are sweep tested to 3 GHz which is many orders of magnitude greater than necessary for 1080p.

The receiver, however, may not pass 1080p over component.

Would you be able to briefly explain what that 3GHz test means and maybe list your 3 favorite brands of 'good' component video cables? Thanks.

Since we are talking about analog signals, the bandwith is the difference between the lowest and highest frequencies that can be carried with no more than a specified amount of loss. I think usually the spec is -3 dB but some may perform even better.

So if the loss spec is -3 dB and the cable has been tested to 3 GHz it means that it can reliably carry frequencies all the way up to 3 GHz with no more than -3 dB loss.

Bluejeanscable.com state that their component cables are tested to 3 GHz and I've seen in the past independent tests of the Radio Shack Gold cables that also met that spec. It's probably pretty safe to say that most reasonably well made cables can carry 1080p with no visually noticeable loss although I haven't spent much time looking for lab tests on every brand of cable available.

that's like, 25 1080p video signals at once.

(if memory serves)

Isn't Blu-Ray also true 1080p?

Yes, but I meant to encompass them all High Def DVDs

Or, some TV may not accept it in component. Some/many projectors want HDMI for this.

I hope this isn't hijacking. My next ? pertains to taking an upconverted 1080i or 720p signal from my Denon 1920's HDMI output that has HDCP and getting it to display on a 1366x768 screen with NON HDCP component and VGA inputs. I imagine I can get that idea right out of my head so I'll ask one more ?.
Should My cable box be outputting 720p or 1080i for that display? The try and see approach is a toss up and 1080i won. Could be psychovideo syndrome though. Thanks.

You are going to have multiple conversions (scaling and deinterlacing) regardless of which you choose so whichever looks best to your eyes is the winner.

This issue is why I don't get the fascination with 'upconverting' receivers and dvd players, especially when the TV resolution is NOT a native HD resolution.

If the cable box gets a 480i standard definition image and 'converts' it to 720p, it will have to deinterlace the 480i to 480p and then scale it to 720p (or it may scale first and then deinterlace - multiple ways to do the same thing). The TV will then turn around and scale the 720p (1280 x 720) to 1366 x 768.

Likewise for 1080i except that it won't have to deinterlace - it will just scale the 480i to 1080i. The TV will then deinterlace to 1080p and 'decimate' the signal to 1366 x 768 (because 768p is less than 1080p).

It's a crapshoot and whatever looks best is the best choice.

Thanks very much for the reply and to everyone else who has responded to my thread

Its interesting you suggested that,i talked with a (Magnolia Rep) at B/B and after a long winded conversation he actually talked me out of a high dollar receiver just to be 1080 p compliant.

He suggested to make my video connections at the Tube and keep Audio-Audio.I liked that idea and it seemed like a good plan and a way to save a bundle on cables.

I bought a Denon AVR 1907 ,its complicated as **** tryin to figure it out by the manual,but it rocks as far as sound quality.

I did look at the 1080 p picture and it sure is hands down better than anything else,iam sure i will venture down that road one of these days,but by then 1080 p might be outdated like 8-track......

Thanx again for the help!

Hmmm,i thought 1080p was only HDMI?....ERR for the quality.

That is what I thought but apparently some will accept it on component.

Ya know all this stuff would give even the finest woodpecker a headache,
It has been splained to me before that this up-converting stuff only ships it in as good as its source and i think alot of people think that s-video up convertin will make it component or HDMI quality and that just aint so,with this said i think its better to leave audio and video seperate and patch it where it belongs and forget up-convertin,there is alot of money being spent trying to make one power amp due all funtions.
