Film grain/noise on Windows desktop

[Meehael]

Hi,

I just noticed that on dark gray background on Windows desktop my laptop screen is experiencing kind of film grain or noise. I have a HP Probook 4720s with ATI Mobility Radeon HD5470.

Why's that and can I turn it off somehow?

Here's a link to a webpage with dark gray background which is a great example where I also experience film grain: http://social.bioware.com/%25253Cbr...bioware.com/forum/1/topic/323/index/9652713/4

Thanks!

Can you use a digital camera, or even cell phone, to photograph the condition? It's hard to imagine, and maybe we are picturing it in our minds incorrectly.

I doubt I could capture it by photographing it, but here's a picture of a plain dark gray background, but with film grain. Just imagine it's animated (like it's snowing, but the white pixels aren't falling down, they move around randomly).
