I've recently got an LCD monitor and it is occasionally 'flickering' colors very noticeably. It's not a new monitor, but the person I'm borrowing it from hasn't had any trouble with it.
The flickering occurs across operating systems and screen resolutions.
I'm pretty sure it's related to dirty power - it often happens when fluorescent lights get turned on or the fridge starts, but not always.
Is this likely to be the cause of the problem?
Is there any good way to test this?
Is there anything that can be done about bad grounding?
