Why will the same graphics card that allowed me to use the flat screen TV when running Windows not display with Ubuntu? Keep it simple please. I am new to Linux, still feeling my way around.
If you're running the Unity desktop: Click on the top left Ubuntu Logo and search for monitors. Click detect monitors.
If you're running Gnome: Click on the appearance menu under system and find monitor. Click detect monitors.
If this doesn't work more details would help to alleviate the problem.
