Issue
Sporadically black bars will go across the top of browsers not allowing for navigation in the browser. This is a Microsoft issue with a graphics driver that does not have a permanent solution at this time. I do have a few things that have worked for others I'd like to try before having the computer reimaged for you.
Solutions
	- Verify that your displays are even in Display settings.
	
		- Right click on your desktop
 
		- Click Display settings
 
		- Then ensure all of your displays are in a straight line
 
	
	 
	- Double click the F11 key.
 
	- Restarting your computer may resolve the issue but the bars may reappear. 
 
	- When the black bars are present click Ctrl+Shift+Windows+B, this will reset the graphics driver.
	
		- This may or may not hold when you disconnect/reconnect to the docking station.
 
	
	 
	- Finally if all else fails have the Desktop Support Team reimage the affected device.
