I went to Convert Colour Space used the profile like destination, I export to eecolor format and then I loaded in.


Yes, I refer that. For people like me, we are learning on the go, this kind of course could be very valuable.

Thanks.

Sorry, what I meant was, are you always watching video through the LUT from a bluray player, for example?
As I say, you have to know the image path that will be used for final viewing.

Yes, I use the LUT with a Bluray player (Oppo) and NVIDIA Shield TV (Android TV, for Netflix), the two are using legal range and it is what I am using to calibrate.

Also, I made a new characterization (17 cube) using the new brigthness and contrast using CalImages and the image (IMHO) is more detailed and clear, I think if could be two reasons:

1) Blue be predominant, usually gives a cold look to the image, looking clearer.
2) The errors are not so "extreme".

Althought, I could (probably) wrong.

What I would do is Burn a Bluray disc with the same CalImages (ContrastCal and BrightnessCal) and check they look the same from all sources.
I think the images from the PC source are being 'converted' to TV Legal via the EDID data from the TV.
If so, they should all look the same.
And if they do, all is good.

Hi.

I used the images with the Bluray, only I converted the images from tiff to png (the Oppo can play images in jpeg and png) and I used it. The three images looked correct.

Also, I made a Primary&Secunadary profile using the Bt1886 LUT. I used the Lumagen mini like pattern generator, I connected it to eeColor with the LUT loaded, I updated min and max values in options and I made the profile, the complete report is:

IMHO (all), the blue is the dominating color and it could be some clipping over 90, also this calibration is visually the best, I think it is for the low deltas (for almost) and the cold tone. The diff gamma is typical of this TV, the only I got a near flat gamma was using the 20 point grayscale of the Lumagen but the image look much dimmer. One thing, I was surprised, the image look more luminous than a Calibration made with the Lumagen with a similar max luminosity.

That is probably the best you are going to get with that display.
There are underlying issues you will never be able to correct - low blue/red gamut being one of them.

Steve

Thanks.

I will try using with other mode (normal), it has to 2 point grey adjustment. One more.
