Resolume Forum

I'm trying to use Resolume to drive my 4m x 2m led wall with an ultra low resolution of 32x16 pixels!

The wall is made up of WS2801 pixels driven by a Teensy microcontroller.
Pixel data is streamed to the microcontroller via a Syphon enabled processing sketch.

Here is the problem......

I have a composition of size 32x16 and I'm triggering png images and the like.
Once I'd switched the Scaling Quality to nearest neighbour they display fine.

However once I introduce a syphon server the image goes all blurry. I think the scaling mode reverts to trilinear as
If I delete the syphon server I have to toggle the scaling quality to trilinear and back to get image to display clearly again.

Is this a bug or is syphon doing some kind of scaling?

And how can a 32x16 pixel image appear blurry anyway without increasing the resolution?

Here's a screengrab without Syphon:
Here's one with a Syphon Server used as a composition effect. Resolume output and syphon client output is blurred.
Finally one with Syphon output enabled in preferences. Resolume output is ok but syphon client output is blurred.

I just found this post:

Sounds like the syphon stream isn't actually interpolating at all - just the displayed image.

If I loop the syphon output back into Resolume (possible potential for interesting feedback effects here?) then the incoming image doesn't look blurred.
