Bonjour Nicolas,
encore un post intriguant sur
http://www.avsforum.com/forum/40-oled-t ... d-468.html
relatif à l'élimination de la postérisation via un calibrage particulier.
Si tu peux examiner cela ?
Je copie ici le post :
==========
I finally got kodi dsplayer all set up on my htpc, spending around two days settling on optimal scaling and image refinement options in Madvr, which means it is now time to get serious about 3dlut.
I may be repeating what others have already said, but in getting ready to make the 3dlut I was able to get a
smoother rise out of black, and also get 18 flashing and 17 barely visible while also having black be black.
The trick is to load up the avs black pluge pattern and then in 2point white balance low set green to something big like +20. Now you should see all the blacker than black bars. further, if you now start dropping the brightness control you'll see that the tv starts clipping these lower bars and they fade away into the greenish background.
My theory was that if I could line up the tv cutoff of "black" with video black, I may get a smoother transition out of black.
So once you lower brightness until the tv clips all the bars up to 17, go back into white point and adjust 2pt low back down until 16 is black.
On my set this was gamma2.4, contrast 75, brightness 49, and white balance low rgb +6/+6/+6.
The result on my set is black is black and I now get 18 and 17 is very very faint.
I also finished a 3dlut tonight. The resulting corrections gave a great result, except for low color temperature in the <5% gray range. I will need to look into what happened there.
Side by side 3dlut vs my 20pt calibration I can barely tell a difference on a still image.
In fact, in motion 3dlut vs just a properly set contrast/brightness/etc is very difficult to tell apart.
