Red streaks in output

Hi all
I'm using a particular setup with an eGPU and Resolume 6, I must say that it works pretty well. One thing I noticed unfortunately is that the DVI output shows red streaks when the scene brightness is low. I believe it has to do with colors represented with small numbers, so parts of the composition which are very dark.

Actually I'm clueless here, I don't know even how to google it. I tried using a DP->DVI adapter and a different cable.

Before trying to exclude the video card (which is hard because the problem shows up only on the led wall and not on the home tv) I wanted to ask if anybody knows about this problem.

I attached a photo showing the defect. Bear in mind that I'm pretty sure it's not a resolume bug, but something with my setup.

I bet this is something related wth the Led Panel Controller and not Resolume. Led panels usually don´t deal very well with color blends, specially with low res models.
Just my two cents.

You're LED panels don't step down to black uniformly so this is common with Chinese panels.

I thought about that, but apparently the problem doesn't show up with another computer with Resolume 5 and the exact same effect.

Is there anything I can do to debug the issue or gather more informations?

To debug make Resolume screenshots of the composition with control + shift + P.
Create a new composition, load this screenshot into this new composition, launch it, and set the output to Full Screen on Display - you use, or a new Advanced output preset where you don't do anything else than resizing slices.

Do this on both Resolume 5 and 6 with the same screenshot, and check if you see a difference.

Found it. It's the monitor color profile. Switch to srgb
