I have 503CMX that is coupled with the Motorola 5100 HD cable box. This box can convert any type of HDTV and DTV signal to either 720p or 1080i. I am finding myself struggling with the decision which signal looks better on the 503. While in both cases HD looks astonishing 720p has smother (film like) feel while 1080i looks more sharp and detailed.


I am just curious to know how other Pio503 users feel about feeding their plasmas with 720p vs. 1080i signals.

I believe matching the source to the set-top output is the best way to go. For all non-ABC, send it out 1080i and let the Pioneer handle it. For all ABC, send it out 720p.


Perhaps this changes with a fancy video processor, but out of the set-top directly, this seems like the best choice.

I have no option to output 'original' format from the 5100. It is either 1080i or 720p ( also 480p,480i) . So I have to pick one or flip output settings forever ;). For the moment most of the worth viewing material (movies e.t.c.) comes out from HBOHD or SHOHD. I guess these are 1080i. I am trying to keep output set to 720p, but sometimes I wonder whether I like the image or just use this settings because I know than in theory it should give better image (more data per push) ;-)

Rogo and I may disagree on this one, but I suggest setting it to 720p and leaving it there. The panels native resolution is 768p and 720p equates to 750p which is pretty darn close to the panels native resolution of 768p. When in 1080i you also lose some of the picture (overscan) as well, almost like you pressed the Zoom mode on your remote. You may think that you are seeing more detail but the panel is not capable of showing that much detail that a true 1080i display would.


Rogo whats up with your 503CMX adventure? Its been a few weeks since they Pioneer took your Plasma.

As you have probably figured my 503 has 5002 card. I wonder how it handles 1080i signal. Does it assemble two 540 fields together into 1080 frame and then scale it down or upscale each 540 field individually (two within 1/30 sec). If it assembles 1080 first and then scales it down it should have mode data to create a good picture at 750 lines. If it upscales 540 – another story.


720p feed practically does not require major rescaling (may be a little bit). In this case all downscaling of incoming 1080i signal is done by cable box (vs. 5002 card).


All this is a theory – practically I am still trying to determine whether I like 720p or 1080i feed to my Pio… ;)

best HD resolution for the PIO is definitely, without a doubt, 1440i. The trick is you have to have an AccessDTV card to do it. 1080i looks much better to me than 720p... and 1440i looks that much better than 1080i. I heard that 1440i is some tricked out version of 720p.... but whatever it is.... whatever it does.... I don't care.... I love it.

1080i looks better to me as well. The pioneer converts everything to 1080i first than to 768 native rate.


This was discussed before. You can find more info if you do a search.
