Thanks Ted. I'll try that, but I think my 2 point white balance is to blame. I restored the values at 20% and now the black background is black again with low-light patches. What this means, I think, is that I won't be able to balance the low end of my greyscale without raising minimum light levels.

What you have to remember is that with blacks you can only balance by 'adding' colour, as reducing will cause clipping.
As a result, the 'black level' will lift.
But, there should be no difference in black level with different sources.

That makes a lot of sense, but I'm a bit surprised finding out that adding color at 20% can lift blacks at 0%.


Perhaps a more targeted approach using the 10 point can help? I will see later today.

I too am surprised that 20% changes are affecting black, but some TVs have poor internal colour management controls.
As we do suggest, you can often get superior results by not using any internal colour management controls.
Just place all the TV settings to their basis settings, to give the best overall image consistency, with black and white clipping correctly set.
Image constancy means the most constant readings across the gamma and gamut, regardless of what the actual readings (colours) are.
Then let LightSpace CMS do the rest wit the 3D LUT.

This is the approach we use with many displays - and the results are near perfect.
See: http://www.lightillusion.com/calibra...omparison.html
The initial display set-up is far removed from the final calibration via the LightSpace 3D LUT - but the results are near ideal.

When replacing a single 3D LUT using the Truvue app, the instructions are: Select 'Display Type'>Standard Non-RGB LED Display>General Media

Would it make a difference if I selected "RGB LED" instead? My Samsung is RGB "OLED" type.

No, it will make no difference at all.
You are specifically replacing the LUT with the one you have generated - the eeColour settings such as Standard Non-RGB LED Display, RGB LED are nit used in any way.
They were only of any value when using the (non-calibration based) original eeColor settings.

I'm a bit confused...

I used DisplayCAL to generate a LUT for my projector. I then selected save and the software generated 7 files: 3 were first1d-red/green/blue and then 3 that were second1d-red/green/blue and a single text file.

What do I do with them now? I believe I saw in the thread to rename to 3DLUT_# with # as the memory slot. Do I name the non-color file to this?

Then what? I see in post #2 what to select in the TrueVue software, but how does it know to use the file I saved? Do I need to put it in a certain folder?

Thanks!

Brian

Edit: Okay...I see these RGB files are not needed, but still need to know what to do with the single text file...

Edit#2: Does it go in TruVue Application/Data/3dtable/standard nonrbg led/General Media/3DLUT_# ?
