Keeps turning a Blueish-green kind of colour when I turn it on. (By that I mean, instead of a nice clear view of things, It has a shade of B-G in it.) Can anyone of you wonderful people help me? - --------It very often turns back to normal after some time, but it's all so random-------
Sometimes monitors will do that if they're not plugged in to the computer properly. Make sure it's completely plugged in, both on the computer end and on the monitor. Could also mean that the cable's connectors are damaged and not giving a proper signal; how long have you had this monitor?
If it's randomly changing, then that's probably a hardware fault, as opposed to a bad setting. I'd try it out with different cables and the like. As Star said, they're the most likely thing to be damaged. You could try plugging in a different computer too, to see whether the same thing happens.
