The game crashed whilst The game crashed whilst initializing game Error: org.lwjgl.LWJGLException: Pixel format not accelerated

This is the error message that popped up on the launcher when I hit the 'Play' button:

The game crashed whilst initializing game
Error: org.lwjgl.LWJGLException: Pixel format not accelerated

I'm not at all sure what to do, so any help would be appreciated.
