Response to Shooting TV, Computer Monitors etc. eliminate flicker?

TV monitors are no problem as long as you are shooting NTSC off an NTSC monitor or PAL off a PAL monitor. If you are in the US shooting off a US TV...don't worry about it. Computers are another thing altogether. High-end Pro cameras have a clear-scan feature which allows you to dial in the scan rate to match that of the computer. Short of that the only other option you have is to try to match the camera's shutter speed to the computer scan rate as close as possible. If you can set the computer's scan rate at 60 Hz. that would be perfect. I can't do that on the Imac in front of me, but I can set it to 1024x768 @ 75Hz. and set the camera's shutter speed at 1/15th which is a multiple of 75 and get a clean image.
