what's the name of the blue cable of new monitor
1 HDMI stands for high definition media interface, basically it's a 2 in one cable that carries the display signal as well as a sound signal. If you use a HDMI cable to connect your laptop to your tv for example, you'll be able to use the TV as another monitor, and you'll also be able to play music through your tv speakers. VGA (the old blue monitor cable) is analogue, whereas DVI (the white connector) and HDMI (usually black) are digital. This means that if you have a flat-panel monitor (it's 2013, I assume you do) you need to use a digital connector to get the best possible picture.
