Acer Aspire 5630 Laptop screen/display problem

Got the above laptop and it's just developed a problem with the
screen/display - there's a 65mm column at the right-hand side of the display
that's gone dark. Applications open up properly and you can see the whole
width of the app, but it doesn't go the whole width of the screen - sort of
full display but not full screen if you see what I mean. Also, don't know if
it's relevant or not but the taskbar at the bottom seems to be twice as tall
as normal and isn't drag-able back to it's usual size - cursor also distorts
in this area.

I'm not explaining it very well, so have a look at this photo:

At first I thought it may be a display driver issue but I've uninstalled and
reinstalled without success. I've also used a program called #1-TuffTest Pro
(http://www.tufftest.com/ttp01.htm) that is self-booting, operating system
independent and never goes anywhere near Windows, but shows the same
results, so I would say that that rules out any Windows driver issues.

Any ideas what's wrong and how to fix it?
