Strange vertical lines in edge focus mode

[sam karr]

Here is a pic of my scarlet dragon monitor (STH OLPF). When I increase the iso and activate the edge focus mode i see these 3 vertical lines, separating my screen in 4 equal parts. I don't see it in RCX.Does anyone have an idea about what cause this or did anyone experience it? Thanx

I have the exact same thing, but I've never seen it in the final footage.

It's very subtle noise patterns being exaggerated by the focus sharpening.

It could also be in relation to the scaling algorithm that is done to get your 5K image onto the small screen. I've seen similar things in RCX before. All on various footage, across various different sensors over the years, but it always seems to be in relation to the debayering quality that's set for the preview. But again, not seen on the final output file.

Seen this. Have seen this for a while. It's just there but not on the R3D. Check your monitor sharpness settings. seems to have something to do with it.

Thanks everyone.
I'll check the sharpness David. I think you're right, I've been messing with the monitor sharpness a few weeks ago.
