Screen shows gray lines

Tekst:

Hi, I've got two gray horizontal dot lines up screen (in the status bar area) and some weeks later a new one, this time vertical in the middle of the screen.

When connecting to a big screen, such as a LG LED TV on the thunderbolt port > HDMI, the lines doesn't appear.

Is this a LCD screen problem? Or could be on the graphics card?

Can someone give me some information about it?

Thanks.
