Monitor makes noise when displaying white.

I have purchased a refurbished 17" Dell E771P CRT monitor - only temporary until I can get a better one of course.

The problem is, I have noticed that when I have white on the screen, i.e. when all pixels are on, it makes a sort of a humming/electrical noise, which is much worse when first switched on especially when it's cold like it is now. It only happens when displaying white, and it gets louder with a full screen of white. I've tested this by maximising white windows (e.g. Notepad) etc, and it definitely doesn't like white!

If I display a full screen of red, green or blue there is no problem.

Should I be thinking about returning the monitor? It's got about two months left out of the 90 day warranty but if it's not serious, or there is a way I can fix it, I might just put up with it.

It's running at 1024x768 @ 85Hz (any less than that and I can see the flickering).

Sorry - didn't finish typing my posting! I should have mentioned that it seems to happen at any refresh rate and resolution. Anyway any help would be appreciated. Thanks in advance,

Gaz
