Display resolution options disappeared

[helpme]

I had an extra monitor attached to my laptop for about 10 min and it was working fine. I tried to adjust the resolution to see if the picture could be more clear. The laptop disconnected from extra monitor and froze so I restarted. Now the option 1680x1050 is gone. The highest it will go is 1366x768, but the monitor keeps saying it needs to be 1680x1050 to work. 

How do I get the additional resolution options back?  I updated the Intel Graphics driver. I tried the Intel Graphics Control Panel. I tried installing Nvidia (not compatible). All roads lead to 1366x768 as the highest option, even though I had more options before. 

HELP?!
