Interference in grey shades

[Fevvahz]

Ive just put together a new machine, and I'm getting something unusal happenning on screen. I started to notice it in games, but I now notice it on the desktop. In some shades of grey, very specific ranges, theres a blue hazy, movign interference. I especially notice it in Steam, when an item is selected. It happens in games too, I notices it in Fallout 3 at night, in the sky textures.

The machine's spec is as follows:
Intel E7300
Asus P5Q MB
Powercolor ATI HD 4850 (1024Mb)
4GB OCZ PC2-5400 RAM
Hyundai N220W monitor

Im currently running the v8.11 Catalyst drivers, and the correct colour profile for the monitor. GPU temperatures climb to perhaps 50 deg. at most in games, but the CPU never gets much above 25 deg.

...any suggestions?

Any idea what it could be?

Theres a chance it could be the monitor, are you able to test the card in another machine or a different monitor on your machine?

I alway notice this on samsung TFTs certain dark colors have "TV noise" style patterns in them.

Are you using a analogue or digital input to your monitor? I get a lot of haziness when using the analogue on my screen, but pratically nothing using digital.

Ive never noticed this before, it seems to only happen after a little use too.

Ive using a digital cable mate, 'cos of too much interference with analogue.
