When companies revamp their product lines they change product names which make it difficult to figure out which new model replaces the old one.

So I made the table below mapping the old to the new.

This comes from some early information and is subject to change/error.

The Latitude product line is due for a refresh very soon. The D-Series family has served me well and is a great choice for a business user.

The purpose of this post is to point you in the right direction about HDMI a semi new type of connection (pictured above).

You use HDMI to connect devices together typically for Hi-Definition Audio and Video.

So it might be a PC to a Display or even a Blu Ray player to a TV.

From the PC End HDMI is the latest in a very long line of Display technology that started with EGA, CGA, VGA then DVI.

You can get converters from DVI to HDMI (pictured below).

HDMI does come with a steep learning curve in terms of specification and compatibility from HDMI 1.0 to 1.1, 1.2, 1.2a, 1.3. 1.3a, 1.3b and 1.3b1 (insanity I know).

Each adding something or fixing something in the HDMI specification.
