Panasonic PX70 fails the pluge test on DVE Blu-ray

[Basil Plumley]

I have a Panasonic PX70 and it's fed an HDMI signal from my Onkyo 905 which has a built in REON HQV scaler.
I orderded the Blu-ray version of DVE and it arrived this morning - and to my surprise, the Panasonic doesn't pass the pluge test - ie, it won't show blacker than video black.
Now - could this be the plasma? Or the REON scaler maybe...? Something in the chain is clipping the signal...I use a Japanese PS3 as a Blu-ray player BTW.

Point to note - I also have an Optoma HD73 connected but haven't tried this yeat as I don't have total light control and will wait until it's dark.

Everything seems to be OK at the white end of the scale.

what settings are your PS3 at ? and your onkyo hdmi out set at ?

 

[Basil Plumley]

PS3 set to 720P and Onkyo set to through...I understand that it's not that important that it doesn't sow blacker than black, but I'm sure there's a problem with the disc...if I run a THX optimode drop shadow test, I get the shadow and all 10 black boxes along the top (Until I turn the black level down, of course...)

might have to dig a bit deeper on this....

Set to full RGB out.

change it to limited

whilst playing your dve . push triangle and move to AV settings, then mess about with the options there. is easiest to change options whilst watching the pluge.

 

[Basil Plumley]

It does lower the overall contrast level once I've had a play with it...but still no blacker than black that is there on SD DVD...

Have you tried your ps3 direct to the Plasma avoiding the amp.? I know its set to pass through but just change the cable and take the amp out of the loop

 

[Basil Plumley]

That's my next plan mate - but setting the amp to "through" should, in effect, do that anyway...

 

[mojo1080]

True . But its worth trying
