Varios calibration documentation on many websites talk about first setting your "player" correctly before beginning calibration of the TV.
One area I am stuck on is IRE setting on a Blueray player (in my case the BD30) of either 0 or 7.5 DEPENDANT ON CONNECTION METHOD
From HOME THREATERMAG...
When troubleshooting brightness for information below black, you can adjust the player's IRE. If there's a choice between 0 and 7.5 go with 0. On some sets this is called DARK for 0 and LIGHT for 7.5. Only have to adjust if you cannot get the drop shadow on the THX Optimization pattern on the DVD to appear when the brightness is turned all the way up. Setting IRE to 0 io so that "Below Black" is being sent to your TV. Otherwise the drop shadow sometimes cannot be displayed and Brightness settings cannot properly be made. This is echoed to some degree in THX's own documentation.
Avical's DVE User-Level tutorial at avical.com and Preparing the DVD p[layer for calibration before starting...
"If there is a black-level control and the composite or S-video output is being used, place it in the 7.5 IRE position (LIGHT). If component is being used, place it in the "0" IRE position (DARK)."
And lastly from Panasonics OWN manual for the BD30 BD Player on page 20...
"Black Level Control
Select lighter or darker for adjusting the black level control to the
desired setting for picture enhancement.
≥Lighter: When video is output from VIDEO OUT or S VIDEO OUT
≥Darker: When video is output from COMPONENT VIDEO OUT
So. You can see a common thread here. If component, set to DARK (0 IRE) and if composite or s-video, set it to LIGHT (7.5 IRE).
Any comments on this from seasoned calibrators is welcomed but more importantly, and the reason I post this is this...
What about when over HDMI!? No one talks about this IRE setting over HDMI. Anyone know the correct setting of IRE for HDMI output from your DVD or BD Player?
I am playing with calibration and I am perplexed by this one.
*EDIT* Here is more I have stumbled upon...
Oh and then I have found this... http://www.avsforum.com/avs-vb/showt...89#post4969789
Guess I have more reading to do.
But at least the answer (upon a fast read through) appears to be in there.
