No secrecy at all. You can find a list here.

Alternatively, download the AVS HD.709 patterns for free from here:

http://www.avsforum.com/t/948496/avs-hd-709-blu-ray-mp4-calibration

Simply burn to DVD or stick the patterns on a USB stick and you're good to go. The AVS patterns are more extensive than the THX patterns, but you only need to use the basic black level and white clipping patterns to set brightness and contrast, while there's another pattern to set sharpness.

Glad someones mentioned thx, i brought the specs and used the t2 bluray to fine tune my tv and i didnt like the result im sure the blacks had become crushed and i suddenly got a few 'plasma' related issues i had not seen before. So anyway i then used the optimizer found on sony dics which took some of my tv settings the other way and the picture was so much better.

But now ive seen this link i may tinker again!

Anyone else have good or bad results using these optimizers ?

You shouldn't use the T2 blu ray version of THX to calibrate as it's not as accurate as the DVD version found on the likes of Star Wars. THX pulled it after that disc and no other THX branded calibration appears on blu rays so use the DVD version if you want a simple calibration, use AVS HD 709 if you want a more accurate result but it can be a little difficult to understand at first so watch the videos first to see how it's best used (they are on the disc once you have burned it).

I used the THX optimiser on my T2 disc and found it useless, I got very similar results to yourself...crushed blacks and contrast that was too strong. When I switched back to the DVD version and calibrated all was fine and it was far more accurate, I have no idea why the blu ray version is so inaccurate though.

There is a calibration tool on some Disney blu rays that I've found quite good and certainly provide far better results than the THX one.

'Oldboy' thanks for this i thought i had maybe not used the disc correctly but i definately followed guides online on how to use the t2 thx, interesting information you have provided there, wish i knew that earlier but it certanly gave an awful picture!!

So have you used the AVS HD 709 calibration or have you stuck with dvd version of thx results or even the disney one which i thought about getting but they bit pricey!

It's not you...you have done nothing wrong it's the disc, for some reason the THX optimiser on T2 is useless.

I've used the THX optimiser on both DVD and blu ray and the Disney calibration tool and would recommend THX on DVD and the Disney tool but I use AVS HD 709 now as it's far more accurate than all of those calibration tools put together. You still need your THX blue filter glasses to use AVS HD accurately but I would highly recommend it as it's the best tool out there unless you go for either a professional calibration or get a colour meter and software and do a full calibration yourself which is tricky.

If you go to the AVS HD 709 site full instructions are given on how to download the file and burn it to disc, take it step by step and be careful to download the correct file type to burn and it's a simple process that is well worth doing. If you have the kit you can download a blu ray hi def version too but of course you need a blu ray drive on your PC for that.

Oldboy, i have finally got round to having a try of the avshd709 last night, only quickly as it was late, so i will have another go.

couple of things popped up, first off, the basic settings no.1 - black clipping, i got this to 16 as suggested then moved onto no.2 - apl clipping, i got this to the 16 as suggested but i had a major difference in the tv brightness setting ie for no.1 the tv brightness was 6 and for no.2 the tv brightness was 22! the instructions say go with apl clipping if this happens which i have, what do youthink have you had this issue?

regarding the white clipping, whats the idea, am i supposed to raise the constrast until i cant see lines after 244 flash? i didnt quite understand the instructions there.

hope you can help, if not no worries
