Hey Everyone,

I have the Avia calibration DVD and popped it into my Blu-Ray player to start making ajustments to my Sony LCD HDTV display. Then I realised that in addition to video adjustements (picture, brightness, color, etc.) that can be made via my TV's AV control menu, there is also an AV control menu on the Blu-Ray with similar contols for brightness contrast and color....My question is how do I balance the two?

What should I set the Blu-Ray AV controls to in order to adjust the video display settings to ensure that the TV is calibrated properly regardless of if I'm watching a Blu-Ray disc (whose own AV controls affect the display) or if I'm watching a TV program (which relies only on the adjustments made on the TV AV's controls)?

I hope that made sense...any help?

The best place to start is to have a review of the player that confirms it outputs video signals correctly. That is quite rare. The next step then is to assume it does and leave things as they are out of the box. Make your adjustments using the display controls.

To go beyond this would require providing a reference video source of test patterns to calibrate the display and then see if your player is matching that response which then also verifies the player is outputting correct video signals. If necessary you could then use the player controls to match the setup you created with a valid source leaving your display settings as is for correct signals. You are starting to get deep into ISF calibrator territory and that can be complicated.

All in all, the key is that you can get the right response with the player using the display controls.

Thanks, for relpying to my post I really appreciate the help.

Bear with me for a moment. If I undersatnd you correctly I need to assure that the signal coming from the Blu-ray player is outputing the proper video signlas and make the adjustments with my TV's Picture Display controls.

Right now, my Blu-ray player allows me to adjust the Picture, Brightness and Color via the player directly apart from the tv's display controls. The Blu-ray's display controls has 3 presets that I can select: Standard, Theatre room, and Bright Room. All of which make drastic differences to the quality of the display. The Player also allows me to make custom settings. So I do not know which seting is putting out the right video signal.

Therefore, if I use the AVIA calibration DVD to display the test patterns by playing it in my Blu-ray player, I think the resluts will be distorted becuase of the player's own calibration options that have drastic effects on the display.

Here is what I was thinking of doing:

1) Display the AVIA DVD through another DVD player that does not have any AV display controls and make the adjustments using my TV's Picture Display controls. This would be my base setting that I know are calibrated properly assuming of course that my DVD is outputting proper video signals. Is there anyway for me to check this?

2) I would then insert the AVIA DVD into the Blu-ray player and make the adjustments to the Blue ray player until everything displays properly without changing my TV's setting.

Does this make sense? Or should I do something else?

Thanks again for your help.

Standard is the out of box setup and typically where correct is to be found. Use that and adjust accordingly...

1) Display the AVIA DVD through another DVD player that does not have any AV display controls

Back to square one - have correct video levels been confirmed? Not having controls does not mean it is correct. It does mean if it isn't and you have another source that is and you are using the same input or are stuck with the same control settings on your display you are stuck which then means you have to change settings for each source. With controls you could correct the player and forget all that rigamoro...

For performance folks we want all our sources to output correct video levels for our display that was ISF calibrated with correct video levels. Makes life so much easier!
