Well i am not sure this is especially CRT or is the case with other displays too.
I've seen some videos in which I see some monitors that are on. But there colors doesn't seem normal and horizontal lines appear to move upwards or downwards, but in real they are quite normal.they don't have any false colors or there are not any lines travelling along y-axis either direction.
I have also seen my monitor from the hole of my EVAPORATIVE COOLER through its fan and i could even see these lines travelling along the y-axis but i think colors were normal.When i directly watched my monitor it was normal and there wasn't any unusaul behaviour.
Is there any problem with my observation or there are some reasons for this behaviour.And also does it happen only with CRT or is common in any type of display if this is a true observation.
