New to using forums so not sure if correct procedure to ask a question!
I have ps3, hd plasma (pioneer pdp507xd), AV Amp (yamaha RX-V2600 (HDMI 1.1, support for LPCM5.1)) and I am unsure as to best connection option.
PS3 auto sets max video and audio resolution supported when connected via hdmi, so when I connect ps3 to amp it will output max 5.1 LPCM but only 720p/1080i (amp wont support 1080p).
When connecting ps3 hdmi to tv it outputs 1080p/24fps but DD/dts5.1 via optical.
Tv is HD (720p/1080i) set NOT Full HD (1080p) but with support (?) for 1080/24 (BD movie native resolution).
Questions:
What exactly does it mean to have 1080/24 support on hd tv and would I get most benefit going through amp to take advantage of lpcm5.1 or outputing 1080/24 to plasma directly (which amp doesent support)?
Is it the case that ps3 output of 1080p@24fps (or 1080i for that matter) is accepted by hd plasma and then downscaled to 720p, in which case there is no benefit in outputting 1080p and I would get more advantage by using lpcm5.1?

There may be an advantage (depending on your TV, it's scaler, and its true native resolution) but it may not be all that noticeable - but that may be the case with the audio as well. Try it both ways and pick what seems to be more noticeable?

I have a pre-HDMI Amp so the choice was simple for me.

Wow.....

Okay, I have read this from the beginning. I have an optoma hd72 projector projecting on a 92 inch screen via HDMI. If I let me PS3 detect resolution, it shows 1080p.

The projector specs are:
Resolution
Native WXGA (1280 x 768)

Maximum Resolution
PC: UXGA (1600 x 1200)
Video: 1080p(1920 x 1080)

Is my projector displaying the 1080 or the native resolution?

Thanks.

The native resolution is the only thing your projector can display, anything else you send to it will be scaled.

The point of this thread is that 1080i60 will result in the same image quality as 1080p24 if your TV can reconstruct the signal correctly. In general you want to keep the signal native and digital as long as you can and save scaling until the very last step, but in reality your mileage may vary depending on the quality of the scaler involved.

I have my PS3 configured to output 720p during normal operation, and 1080p24 when watching a Blu-Ray movie, and that may be a good starting point for you, but your mileage may vary. That's why there's no one answer here.

ugh...

intents. and. purposes.

"IBTL" isn't cute, funny or original.

Also: you couldn't care less and purposes are NOT intensive. For all intents and purposes if you don't know these things, you probably shouldn't use them.

Thanks for the reply. I realize my question was a bit off the main topic of the thread.......sorry for that.

I will try those setting later. I have to admit I was expecting more in image quality from Blu Ray than I was getting on my oppo upconverting. Perhaps it's a limitation of my projector or if I was in fact asking my projector to "scale" the image.

Thanks again.

This question is one I need an answer to before moving foward on a Blu-Ray player purchase. When I purchased my HDTV, 1080p was really expensive. The best I can do on my set is 1080i. Is getting a blu-ray player worth it when you do not have 1080p display?

Even 1080i is a far site better than 480i, I wouldn't worry about your current TV. With properly mastered BRs you'll see a big difference from 480i SD DVDs.
If you're going to be playing many SD DVDs you'll want to look into one of the better(more expensive) BR players with better scalers.

If you use "1080i" in the advance search engine, title search only...you'll find others have asked similar/same questions about this type of set up.

I've purchased LG 50PK950 TV which has Netcast. Is there any reason then to purchase a blu-ray player that has wi-fi?
