That said, it is going to take awhile for DisplayPort to gather momentum. Also the packet approach allows for alternate transmission media like fiber optics, as well as additional data streams such as multiple video signals, audio streams, or even internet packets. It is a high bandwidth packetized digital signal with significantly more headroom to support higher maximum resolutions.

DVI and HDMI are nearing the end of their evolution because the technology cannot support further increases in the maximum resolution.ДisplayPort is significantly different. HDMI is basically DVI with analog VGA compatibility removed, audio channels added, and a more consumer-friendly (some would say flimsy) connector. DVI also includes pins for analog VGA signal for backwards compatibility. This is due to the rise in prominence of digital flat panel displays, where the digital signal is вЂњnativeвЂќ to the underlying hardware in the same way that an analog signal is вЂњnativeвЂќ to a CRT. DVI is essentially a digital version of a VGA signal, where analog voltage changes are replaced with digital values. Originally there was VGA, which is a purely analog RGB signal. My understanding is that the evolution of display connectors is something like this: Some HDTV accepts 1024 by 768, others only understand HD resolutions, etcвЂ¦ so your videocard should be versatile. I mean that if you select an output resolution for your HDMI port compatible with your LCD monitor, it will work.Д¦.Some projectors only have an HDMI ports but dont use HDTV compatible resolutions. The Resolutions you choose on an HDMI port depend on the Receiving Hardware compatibility. Your LCD normally receives a muted digital signal of a certain resolution from the DVI port

RCA, S-video and Composite are the same Analogue Signal NTSC/PAL but over different cable. While VGA is an Analogue Signal of a certain resolution and refresh. HDMI acts as a Dvi Cable and a SPDIF cable into one.ДVI is a mute digital signal without sound of a certain resolution and refresh rate. HDMI is mainly to allow easy plug-in with HDTV so that your HDTV setup is not using 2 cables to connect Digital Sound and Digital video. check your LCD-DVI cable-end, to choose the proper adaptor. Use an HDMI to DVI cable or adaptor they are dirt cheap.
