As you've probably guessed, when recording video with a computer monitor in frame I am getting banding. I'm aware that this has to do with refresh rates of the monitor vs the scan rate of the camera or something like that. I've read that most cameras have a feature to adjust for this - synchro scan, clear scan or variable scan is what I've seen it referred to as. However, I can't find anything on what or how to do this with my Canon t2i.
I've seen a number of videos where people do this with a t2i, so I'm sure it's possible, I'm just not sure how to set the camera up properly.
I've noticed that I can adjust f/stop and shutter speed to get varying results when put in to Tv mode. I'm having trouble getting to a setting that has minimal/no banding and isn't either under or over exposed.
