More than an annoying problem

Right. Well i have a toshiba laptop which i use for everything. i have no idea how it happened, but basically all my colours have inverted. Print your screen, slap it in paint and hit Ctrl+I and your seeing what i now have to use. Its really annoying.
Its definitely nothing to do with high contrast, so that leaves the graphics card. Its Intel if that helps. Ive been poking around with if for weeks now and i cant seem to fix it. I know my description of the hardware is vague, but to tell the truth i dont know that much about hardware.
If anyone has had this problem before and knows how to fix it i would be extremely grateful.
Ive attached an image of the graphics properties if that helps (inverted in paint so it looks like it should).
Thanks.

well this is odd. Your inversion to make it look right to you has made it inverted to everyone else. Is this an actual laptop? I have the same driver in my mac mini. Try "upgrading" your driver to the generic pci driver and see if the problem vanishes. It will use the same hardware but different software and that will help to narrow down the issue.

Another option is to rollback your system to a restore point before the problem happened. This will eliminate settings as the cause of the problem. However it will forget about any programs you've installed since then (although they will still be on the hard drive)

You could try whether it will still be the same on a monitor / tv. This way you'll know whether its just the display that has gone wrong.

I googled "toshiba laptop" "inverted colors" and it seens to be a fairly common problem. Does this help at all?
