I am looking for an external LED display, and one the features I am looking for is "image stability" (probably an incorrect term). With this I mean an image that does not flicker, as similar as possible to printed paper.

This should not be related to refresh rate, which is "the number of times the image can be changed per second, expressed in hertz (Hz). ... Determines the maximum number of frames per second (FPS) a monitor is capable of showing." (ref. Wikipedia)

"The closest equivalent to a refresh rate on an LCD monitor is its frame rate, which is often locked at 60 fps. But this is rarely a problem, because the only part of an LCD monitor that could produce CRT-like flicker—its backlight—typically operates at around a minimum of 200 Hz." (ref. Wikipedia).

Since I noticed that different LED displays generate different levels of "flickering", I would like to know which parameter I should look at to pick the right model. I never noticed anything related to backlight frequency advertised by manufacturers.
