Is the GH2 display always representative for spotting light/beamer interference?

[dtr]

Hi,

I'm an audiovisual performance artist, working a lot with projections and other artificial light sources. I got me a GH2 to document my work and I was wondering if the GH2's display is always accurate for spotting interference of shutter speed, frame rate and electric light sources resulting in flickering and pulsing in the recording. The display has a refresh rate itself so I could imagine it adds an inaccuracy factor. Anyone's got advice on this?

Thanks, Dieter
