Question with cameras and monitors

Colt_0pz

Why is it that whenever you look at a monitor through a camera that the display flickers? how can the camera pickup this flickering and the human eye can't. My display runs at 144hz

Out of sync. Camera and monitor.   and with the filters on top of the screen, and it is the backlight flickering most likely. (in the most basic explanation) 

 

Human eye blurs it.  (in the most basic explanation)

Camera shutter speed and video frame rate vs. monitor refresh rate.  The human eye doesn't have a shutter, it processes images continuously.  But a camera's image sensor has to have a shutter, either mechanical or electronic.

To put is simply, a display flickers on a camera when your camera fps is lower or higher (cannot remember which) than the refresh rate on your display.

Most monitors use high-speed flickeringto controp brightness. Turning the brightness of the monitor up to 100% will usually eliminate the flickering if you need to film something on it.
