Sounds like your system is either defaulting to 'Safe mode' properties or you may need to reinstall/update your display driver.
Try updating the display driver through device manager.
Hold down Win Logo and Pause/Break key> hardware tab> Device Manager>
Go down the list to Display Adapter and click the cross to the left>
Right click on the driver name and left click update driver then just go through the wizard.
If you get an error it may be worth downloading a new one from the manufactiurers website.
HTH.
