ELI5:Why is it that when flies land on our LCD/LED screens, they don't get affected when we move windows or make some rapid movement which results in some colour change in the screen?

Fly fear responses are based mostly on air currents and visual stimuli from above the fly, because that's where predatory threats come from.    They don't have much in the way of general intelligence, and escape responses are hardwired so they can be faster, so random visual stimuli from unexpected directions don't really register.

If you want to see something funny, though, put a little jumping spider on a computer screen.  It _will_ follow the cursor around like a cat after a laser pointer, because jumping spiders are incredibly visual and keyed to look for prey running around on surfaces.
