I have the DMP-BD605P-K connected to my Onkyo HT-RC160 via HDMI cable. I then have an HDMI cable to my HDTV from the HDMI out on my Onkyo. The weakest link in this setup is my HDTV. It's an older Visio GV46L - 46" LCD HDTV. It's basically a 720p HDTV, but can accept 1080i.
, I hope you enjoy your BD60 as much as I do!
Like you, I am also using a 720P HDTV until I have the $$ to upgrade.
To force the BD60 to output a 720p signal
Ok, so under "Digital audio output" I have "bitstream" selected for both, and "BD video secondary audio" set to off. Then I have "Component video resolution" set to 720p. Under "HDMI video mode" I have "HDMI resolution" set to Auto.
, you may need to set the HDMI Resolution
to "720p" setting. The "Auto" setting may or may not choose the HDTV's native 720p resolution.
FYI: The Component Video Resolution
setting is immaterial since you are connected via HDMI.
With that said, I originally had the DMP-BD605P-K set at 1080i under both "Component video resolution" and "HDMI resolution" . But, after reading through many threads, I'm not sure that is the best setting. (IT DEPENDS) As I understand it, blu-ray disks are 1080P. (TRUE) If my settings were 1080i, then the DMP-BD605P-K has to down scale from 1080p to 1080i. Then it sends that through my receiver to the HDTV where the HDTV down scales it even further to 720P. Is this correct? So it's getting processed twice right?
The 1080p to 1080i change is called "Interlacing
" and the 1080 to 720 change is called "Scaling
". Some folks not-quite-acurately lump these two separate and distinct processes together and call them "up-conversion" or "down-conversion".However, your premise to reduce the number of video processes is generally correct.
The BD60's and the HDTV's deinterlacers and scalers are not the same.
So am I better to have it set up the way I have it now? That is 720 p out of the gate? That way the DMP-BD605P-K down scales from 1080p to 720p and then it's displayed on my HDTV at 720p. It's only getting processed once right?
Theoretically you shouldn't, but sometimes you might, get better results by feeding a 1080i signal to the HDTV.
Therefore, try both to see if there is a noticable improvement in 1080i. But, if you don't see an improvement, stick with 720p (this avoids "interlacing" a "progressive" signal). Your display is designed for a 720p
, i.e. progressive signal!
Clear as Mud??
