Answer 1

Hi.DVI (Digital Visual Interface) and HDMI (High Definition Multimedia Interface) are high definition digital video cables to improve the video image of a High Definition TV.As far as image quality is concerned, DVI and HDMI are one and the same thing.They use the same protocol to transmit digital data from the source to the display.The HDMI cable is also able to transmit uncompressed audio digital signals on the same cable.As far as Projectors having the capability to connect these cables there is no way of knowing until you select a brand which appeals to you .By the way it is not possible to predict whether DVI and HDMI cables will perform better than an analogue video connection.There are significent differences in the way digital and analogue signals are handled that are heavily dependent upon the characteristics of the source device and the display rather than on the type of video connection in use.

Many people assume that while analogue is always subject to an element of degradation,digital transfer of information is error free.The information is represented by just "ones" and "zeros" therefore it makes sense that the information received at the display is an exact replica of the information originating at the source.However, HDMI cables are subject to a maximum of about 15 meters ,a distance which can easily be exceeded especially in dedicated home theater installations using a ceiling mounted video projector.Futher more DVI and HDMI do not use error correction, therefore,once information is lost,it's lost for good.

DVI and HDMI are distinctive connectors which could carry the comparable digital indicators. The DVI connector is larger, and it additionally has pins for non-obligatory analog indicators. The HDMI connector is smaller, and it has no provisions for donning analog indicators. you may get adapters that regulate from one to the different. HDMI may additionally comprise audio, on a similar time as DVI would not. factor video makes use of three indicators to hold image techniques. It makes use of three RCA-sort connectors. factor can carry all styles of video, from 480i to 1080p. Composite video scrunches the image techniques right down to a single sign, and it may in basic terms carry 480i. Composite is almost the worst thank you to flow video, on a similar time as factor is the wonderful way using analog indicators. factor video could be as stable as using DVI or HDMI.
