Or is it more of an individual thing ?

The closer you sit to a screen the easier you'll spot flickering. that's because flickering is mostly detected by the sides of our vision (and not by the center of it). So when you're sitting 1.5-2.5 times the screen size, and almost all of your eyesight is absorbed by the image, it is really easy to spot flickering, and could become really annoying after a while.

Refresh rates and flicker are a much bigger issue with CRTs than with digital projectors. Digital projectors do not have a raster that the image is written onto. There is no "sweeping" of the constituent image lines across the face of the tube. Many digital projectors have a native refresh rate that they desire to be driven at.

Most of us set refresh to be a multiple of the film frame rate of 24fps. That's why 72 is often chosen. Those with really fast projectors will sometimes use 120 since its an even multiple of both 72 (film) and 30 (video) frame rates.


But, there are other sources of what can appear to be flickering. If you are seeing it when the camera pans, then it might be something completely different. What is your source device? Is it an HTPC by any chance?

Don, so you're saying digital projectors are like LCD computer displays (digital flat panels), where refresh rate has no effect on flickering ?.

Dean, that was strictly an academic question, but while I'm at it, why have you mentioned the HTPC?, is notorious of making the picture seem flickering or something ?
