Why is my laptop's screen turning purple?
I have not yet been able to diagnose the cause (drivers seem up to date and nothing obvious in the EventLogs) but I found a work around. If your laptop (mines a HP 4540) will display the boot screen but turns purple after login (as mines does), closng the lid and letting the machine go into 'Sleep' and then opening it up seems to work.
There are small to large, Netbooks (7-10 inch screen), UMPC's (11-13 in screen) , Tablet PC's (13-14 inch screen), Small Laptops (13-14 inch screen), Medium Laptops (15 inch screen), and Large Laptops (16-21 inch screens). Then there are Media Computers, normally the size of a tissue box. The average computer, and large sever towers.
