Connectors: D-Sub, DVI, TV-Out
Can someone explain which each of them is and what functionality they offer?

d-sub is for older monitors and some new flat panel ones. It carries analogue signals.
DVI is for some newer monitors, and can carry analogue or digital signals.
tv-out is for connection to a tv so you can play games or tv on, unsurprisingly, a tv. :)

Your user guide usually has good pictures if you can find it (worth 1000 words).
It sounds like your card gives you the 3 common choices for hooking up to your monitors. The D-Sub is probably the standard VGA output to a CRT. This is also commonly used to hook up to LCD style projectors.
The TV-out is as it says as well, a RCA style jack to go to the TV inputs (or on your video receiver).
The DVI is the newer style connector which replaces VGA. Any new monitors will support this but older models (older than a few years) probably will not. There are two modes in DVI but it should auto-select between them.
The newest interfaces are the HDMI which carry audio and video connections, is showing up on DVD players, TVs, and monitors as they all become compatible.

D-sub is analog which means that it is prone to interference and has a limitation on the highest possible resolution. This type of connector will not be able to provide enough signal to run the largest monitors.
DVI can mean any number of things, but in all cases it is a fully digital signal. A DVI connection can be one of three types - DVI-I, DVI-D or DVI-A.
DVI-I:
DVI-I contains both the digital and analog connections, (DVI-D + DVI-A) , it's essentially a combination of DVI-D and DVI-A cables within one cable.
DVI-D:
DVI-D (like DFP or P&D-D (EVC)) is a digital only connection. If both devices being connected support a Digital DVI connection (DVI-I or DVI-D compatible) and are compatible in resolutions, refresh rates and sync, using a DVI-D cable will ensure that you are using a digital connection rather than an analog connection, without playing around with settings to assure this.
DVI-A:
DVI-A is really rare. Why use a DVI connector when you can use a cheaper VGA connector? see DVI-I P&D-A (EVC) is more common with projectors, and you should go to your projector manufacturer for recommendations.
Dual Link: Dual T.D.M.S. (transition minimized differential signaling) "links". DVI can have up to two TMDS links. Each link has three data channels for RGB information with a maximum bandwidth of 165 MHz, which is equal to 165 million pixels per second. Dual-link connections provide bandwidth for resolutions up to 2048 x 1536p.
Single Link: Single T.D.M.S. link. Each link has three data channels for RGB information with a maximum bandwidth of 165 MHz, which is equal to 165 million pixels per second.
Bandwidth for a single-link connection supports resolutions of over 1920 x 1080 at 60 Hz (HDTV).
TV-Out is simply an analog SD output to television. This is the lowest resolution option and goes largely unused. It would be handy for hooking the computer to a TV to play games, or to hook to a VCR to record output from the computer. You can use this simultaneously with either of the above options to have a high resolution computer display in tandem with the SD television.

TV-out is a connection for your TV
DVI is Digital Visual Interface designed to maximize the quality of digital displays like flat panel LCD's
D-Sub is probably the standers VGA output for any monitor
