It won't make any diifference to the potential attacker. His aim is to recover the text/shapes of what you are displaying. He is not generally concerned with the "niceness" of the display, but rather the contents. But of course. But what I want to know is: is there some combination of display colors that will be visible for the eye, but not for the Tempest equipment?
Also, many guns - red, blue, green actually do radiate on slightly different frequencies, allowing differentiation of signals - due to the slightly different physical geometry of the guns themselves.
That might answer it. I suppose that if some "stealth" settings exists, they are highly hardware dependent. My question was not "would it work in all instances?" but rather "had this tactic been implemented successfully in *some* instances?" Or, to the contrary, is it reasonable to assume that modern Tempest equipment can work around theses impediments almost all of the time, therefore making any attempts at this futile?
