eeColor Box Clipping Black levels

Hi There.

New to the forum, and have some problems with our new eeColorbox. Here is my setup:

Resolve - BMD 4k Extreme - AJA HI5-3GS - EEColor Box - JVC RS25 Projector.

Everything is set to data level.

After we have downloaded the "Unity" and ticked both "eeColor 3D tables" and "Calibration Tables", I look at the "BrightnessCal.tif" image and the 7 top left boxes getting clipped when we turn on the eeColor box. I have tried turning on and off the "Software" in the eeColor Box, and the clipping happens only when it is turned on. If i remove the box from the "chain" and view my output straight from the AJA HI5 3G it looks the same as with the eeColor Box software turned off.

So I tried to generate a new NULL LUT from lightspace, encase the unity LUT from lightspace was corrupt and uploaded it to the box. Same issues.

Any ideas on what I am doing wrong?

Hi Oliver - as per our e-mails I am bringing eeColor into our discussion to see if we can isolate what is happening.

As we have discussed, this is not normal/expected operation.

Hi All,

I have a similar issue and setup: Resolve -> BMD mini monitor 4k via HDMI -> eecolor via HDMI -> cg247x hdmi input. I see the first top row 4 patches clipped with the unity lut and 7 clipped when I load the calibration-LUT in either Resolve or the box, which I created with lighspace quick profiling and the LUT-box switched to LUT-off. LUT-off shows all but the very darkest patch, same as if I connect the display as a desktop. Gamma is 2.2 and I am going for a 709 2.2 calibration. The pre-cal measurement show a perfect gamma, doing quick profile.

I would appreciate any help.

If I remember correctly you need to replace the 'other' (2nd) 1D LUTs in the eeColor with new bypass LUTs.
LightSpace will generate those for you.

Thanks Steve, I have the old quick profiling license of LightSpace, so I am not allowed to do the 'Edit/LUT Manipulation/Prepend/1023->64-940'. I tried just creating a "new" file in LS and exported to this 2nd LUTs, like you describe on your website, to see if that would be a unity LUT, but it also crushed the image.

I would be happy to load the LUT in Resolve without the box or having the box LUTs off, but it crushes the image. Can you think of a reason? Something is going wrong with my calibration I assume.

I do not think you need any LUT manipulation.
You need to just export a Unity LUT in the 2nd 1D LUT format, or the 1st 1D, or both...
Basically, replace them all...

See: http://www.lightillusion.com/eecolor_manual.html
The section on 'REPLACING THE 1D LUTS'.

Thank you. Replacing the "1." LUT as well helped. Why they are shipping their device messed up is really confusing. Hope you get some percentages.
