You could try removing the display device in device manager then rebooting. At boot up windows will reinstall the drivers.
Check for new display drivers at Dell's support site.

sound like the screen control on the flyback is set just a little too high. the flyback has the red wire attached to the tube. the flyback has 2 small adjustable controls. if you look close enough 1 is marked focus & on is screen. turn the screen slightly to the left & look at your picture. the screen is like a master brightness & if it's up too high you will see what is called retrace lines. good luck.
