Lines/patterns/moire on DSLR footage of computer monitors.
Hi.
Very common in my past having shot footage of different computer screens (Dell LCDs, iMacs, iPads) with my Canon DSLR, and getting these moving squiggly lines on the screen. I’ve tried adjusting the shutter speed on my 5D/7D one click at a time with the dial (have gone to both extreme ends.. lowest to high shutter speeds) in live view mode, with only very minimal improvement, if any at all. And it gets better or worse depending on angle sometimes.
I’ve attached an image to illustrate what I mean.
I shoot computer screens often in my line of work, and need to find a fix for this. Does anyone know what I can do? It’s pretty noticeable in a lot of the shots, a lot more noticeable than this image too.Thanks

You might have thought of this already but try lowering the resolution on the monitor you are shooting or trying to record.
The DSLRs line skip, and only resolve about 700 lines vertically with the best lenses. Try lowering the monitor resolution to 720 or 768 lines vertically and see if that fixes the problem.
If lowering the resolution is not possible, the you might want to try a screen recording software instead, or use a diffusion on the monitor, etc.
Hope this helps.
