DVI vs RGB
In the quest of having the best multimedia experience, movie watchers and media fanatics are always on the hunt for better video, better media connections and the best movie or video experience as a whole. To achieve such, people have long tried on experimenting with cable connections, computer to HDTV connections, as well as, component to LCD TV connections. Up to this time, many are still confused as to what is the best connection in order to have the best video experience. Well, it all depends on what connections you currently have but if ever you happen to have all, then better choose for the best one. In comparing DVI and RGB for example, you first have to take a look at the input and output slots, as well as, the physical characteristics of their connection cables. Foremost, the RGB slot is composed of three rows of 15 separate holes or channels. They are definitely not the ones you see that is colored red, green and blue channel. This is often the cause for confusion in most people.
The RGB connector is the same with the VGA connection and D-sub (D-subminiatures). Their connectors are usually composed of 15 pins that are separated in 3 rows (5 each row). This is the usual connection made for those who want to connect their laptops or computers to a projector or to an LCD TV. This connection does not carry an audio signal thus it usually requires a separate 3.5mm black audio cord to deliver the sound from the source. The female RGB slot is almost always seen at the back of the PC or laptop as the VGA-out of the source. The signal is then carried using the VGA or RGB connector to the backside of the projector or the LCD TV that also has a corresponding female VGA-RGB slot. The connector is thus the male RGB with the 15 pins in place. It is also important to take note that an RBG connection only establishes an analog connection. But still, its picture quality is undeniably better as opposed to other more primitive connections such as the S-Video and the composite video line.
On the other hand, DVI is an acronym for Digital Visual Interface. It is a high-end quality video framework for digital displays. This carries digital video to a display medium without compressing the actual data. The resultant picture is really superb, no wonder it is well-matched with the newer HDMI or High-Definition Multimedia Interface. This is also one of the reasons why it is relatively better than the VGA or RGB connection.
The physical appearance of a DVI connector also varies depending on the signal that it implements (DVI-D, DVI-A, DVI-I and M1-DA). But generally its connecting cables have several pins (usually more than 15) that match the slots for these signals. As a whole, the DVI connection establishes a digital line from input to output.
In a nutshell:
1. DVI establishes a digital connection whereas RGB is analog
2. DVI technically has a clearer and crisper picture compared to RGB
3. The RGB slot or connector is usually composed of 15 holes and pins respectively whereas the number of pins for the DVI varies depending on the signal it implements.
