    Ive been wondering this for a little while so I decided to ask. My M1210 has a VGA (analog) port to connect to an external display. Now we all know that VGA has a lower image quality than DVI (digital) connections. So im wondering, and not only my notebook specifically, but new ones in general, are their internal connections to the display VGA or DVI?

    It depends on the graphics processor. Some of the more advanced ones, like the ATI radeon x1600 have DVI outputs. Most others have VGA. Some even sport both VGA and DVI.

    Yeah I know about the external ports. Like mine has an external VGA, and no DVI. My question is what is connecting the video card to the LCD on my laptop, and new ones in general. Are they internally connected by VGA or DVI connections, and if they vary, what is it that decides it. The level of the video card?

    The internal port is mostly LVDS, which is also a digital standard and which offers the same image quality as DVI.

    LVDS is the signaling system used with most flat panels in laptops. FPD-Links (Flat Panel Display Links) are the actual interface (like DVI) that most laptops use to connect LCD panels to graphics boards. FPD uses LVDS.

    Another interface used in modern laptops is called OpenLDI which also uses LVDS signaling.
