I bought a couple ViewSonic 27" monitors a while back for my dream system, and so far, I've loved them.
Then, all of a sudden, one of them started making strange high-pitched clicking/blinking noises and it got more and more consistent with time. My monitor was still under warranty, so I contacted ViewSonic and shipped it to them yesterday as an RMA (cost a TON of money: note to self, always ship things yourself rather than paying someone else to do it.) Hopefully the refurbished unit I get back will be good quality and will be pretty quiet.
Then, this morning, I realized that the other monitor was doing the same thing, albeit far less often. !$!@%!@!!! Luckily, it has seemed to stop for the time being.
Is this something normal for LCD monitors to do?
