Does my A/V Receiver need to be 1080p HDMI to work with my 1080p LCD TV?

[thadbosley27]

I am buying a 40 inch Samsung 1080p HDTV. I am trying to figure out what home theater receiver to purchase. I cannot find anywhere if the receiver needs to be able to support 1080p or is the reciever simply a passthrough and doesn't care what signal is coming from the source to the TV.

I'm not quite clear what you are asking?

You say home theatre receiver, Do you mean audio only or is it for video? Audio I'd be guessing that your TV can feed audio to it.

In my case my Dishnetwork feeds my 5.1 sound through a optical cable. It is a few years old and only supports analog/optical audio, FM/AM radio and S-Video/Composite video.

I'm think you might want to be sure it supports HDMI switching so you can use it as a switcher between sources. OTOH you only say source but do not clarify what type of source, Satellite. OTA, HD player, Cable etc.

Sorry, I will try to clarify:

I am going to use my reciever to switch between sources, PS3, HD DVD, 4DTV, etc....they all have HDMI connectors. My TV has 1 HDMI input, so I will need to control the switching of the devices in the Home Theater reciever. I found a Pioneer reciever that has 4 HDMI inputs, and 1 HDMI output. So, my question is does the reciever HDMI inputs have to be 1080p compatiable to work with the 1080p of the PS3, HD DVD, 4DTV, etc........or is the HDMI input ports on the receiver simply a passthrough and whatever signal is broadcast from the source will get to the TV without scaling?

I hope that helps......

HDMI is an active connection. The receiver should support active switching and it will if following HDMI spec. The potential problem arises if and when HDCP encryption is applied to HD/BD DVD and ATSC (broadcast, cable, DBS, etc.). Then the receiver needs to be capable of maintaining encyption through the switch similar to the Gefen below.

So, if I understand what you are saying correctly, I should be fine.

The receiver has 4 HDMI inputs and should be able to switch between the inputs just like that switcher you are showing me. The model of the reciever is Pioneer VSX-84TXSi.

Thanks for the info. Sometimes it is hard to keep up with the every changing specs.

It should work.

Hi...just saw your question....it may or may not work. I bought a Yamaha HT 5990 A/V receiver that has 2 HDMI inputs and one HDMI output to my Hewlett-Packard DLP TV that accepts a 1080p signal. When I got a dvd player that upscaled to 1080p, there was no picture from the receiver to the TV. I got in touch with Yamaha and they said the receiver would pass 1080i but not 1080p....there was nothing in the literature or manual regarding this, or I would not have bought. So you might want to check with the manufacturer and the forums to make sure a potential purchase will pass the 1080p ....

The problem is the HDMI is an evolving standard. When you buy a hardware solution you are buying the then current HDMI version without update potential short of a recall.

That said, 1080p should be possible over a 1080i connection unless there is some minor firmware issue.

Which DVD players upscale to 1080P? That is interesting.

The Samsung HD 960-- it does a decent job and will do until the BluRay and HD DVD thing settles down

480p/23.976 film source to 720p/59.94 is usually better than 1080i/29.97 for most HDTV displays. 1080P probably won't be any better for upscale and few HDTV sets will accept 1080p as 59.94fps but might as 23.976 which is the ATSC mandate. If it does accept 23.976, the HDTV must frame repeat to get rid of the flicker.

PS: HD 960 manual won't download. Tell me the frame rate it uses for 1080p.

I agree with your points...the HP Pavilion MD6580, however, does take the 1080p signal at the 24,30 and 60--and HP says its native rez is 1080p, although there's some arguement about that due to its a wobulated 1080p...but from my experience so far...whether that's better than the 1080i seems to depend on how the quality of the dvd.. here's a link to the tv with the specs... i've been really happy with it so far ... and the samsung player was bought more on a lark..i also use DVDO vp 30 as switcher/scaler--

Well, I doubt you will see a difference from 720p/59.94. They don't describe the TV processing very well.

1080p/23.976 needs to be frame repeated 3 frames then 2 frames to get rid of flicker. 23.976 to 29.976 1080i telecine will need a good IVTC followed by the 3/2 frame repeat for progressive display. It isn't clear what the HP MD6580n does for display, it just talks about accepting 24/30/60 frame rates. Never is cinema deinterlace mentioned for 1080i/480i.

[scribe5]

yeah...very few companies lay out what exactly their products do or don't do...hence the problem I had with the Yamaha receiver..it's always buyer beware -- not sure about the the HP deinterlacing either... reviews I've read didn't say

[edDV]

I think we are 5 years before these HDTV's process the video to the level we want to assume. We feed this by ignoring their expensive models for the cheap junk with hype 1080P labels without question.

[scribe5]

some of these companies are walking very close to deceptive advertising--either by an outright falsehood or by omission....i expect a sharp lawyer will see an opportunity for a class action suit...especially if he/she gets burned on an HDTV purchase

I'm sure their lawyers have worked out a 1080p justification for a HDMI native 1080p/24 HD/BD DVD source if not from anything else.
