I learnt something new today after finding what appeared to be marks on my Hazro! turned out not to be marked but instead what then appeared to be screen burn under where the Vista sidebar sits:
After some Googling I came across the correct term and type, Image Persistence.

My screen is in use pretty much all day and on most nights I forget to turn it off before going to bed resulting in a static desktop being displayed the while time. I've since re-enabled the screensaver
so much for not needing it eh 
I know it's not a screen damaging issue like Screen Burn and you can restore it to its original image using the methods described on the Wiki but it's a bit annoying when it's there!
