Tip & How-To about Computers & Internet
If you have trouble getting a display on an external monitor, the issue can be resolved by making the proper settings in the Video Driver Control Panel applet, instead of the Windows Display Properties.
The issue occurs when the display settings for the external monitor are set higher in the NVidia Control Panel than the monitor could display. The settings overrode any Windows Display Properties setting. Similar issues have been seen with the Intel GMA Graphics Controller.
These issue occur docked or undocked with a variety of external displays, projectors and TVs.
So remember that the NVidia and Intel Control Panel settings override the Windows Display Settings.

It is either the lcd panel OR the video card / motherboard or it could just be a completly bad driver.
If you turn it on and hit f2 or f8 does it appear in this screens?
If not, it is a bad driver.
If a bad driver, turn on hit f8, choose low video resolution mode, surf to your manufacturers website, download, install and reboot.
Try display to an external monitor, if the line appears on the external monitor, the issue is a bad video card.
you will need to connect to another monitor or your television to your computer with the vga lead monitor connection
click start control panel display change display settings adjust resolution this may vary depending on your operating system you should a no 1 and a no 2 with detect and identify keep an eye on
the screen when you select the number tabs this may vary depending on your operating system when you select the no 2 tab this should be the extended desktop always click apply after making any changes
If the issue does NOT appear on the external monitor, the issue is the lcd panel.
Hope this helps
