DVI is a fairly new specification that also defines a new connector for use with displays. It aims to replace the aging D-sub connector for displays currently in prominence.
DVI was purposely developed and designed to transmit video signals. In comparison, the D-sub connector is used for a much wider variety of applications. This includes but not limited to VGA displays, serial ports, parallel or printer ports, game pads, and even for mice.
D-sub connectors were steadily being replaced by other types of connectors, the most prominent of which was USB. The only D-sub connector that is still being widely used nowadays is the DE9 connector for monitors. DVI is capable of transmitting both analog and digital signals its D-sub equivalent the DE9 only carries analog signals.
Though other D-sub connectors like the serial port uses digital signals, the provisions in the VGA standard only allows analog signals. In terms of the actual connector, the two looks very similar as they both sport the shell that looks like a lying down D, with the curve on side to ensure the proper orientation of the connector.
DVI is specific to video displays and there is really no point in having a wide selection of connectors that can be confusing. There are three standard connectors for DVI with the standard DVI connector for desktop computers and the smaller version for smaller devices like laptops.
In contrast, there are five standard shell sizes for D-sub not to mention the great number of pin count and configurations. This is a direct consequence of the wide number of uses of the D-sub connector. Integrated Intel Graphics Media Accelerator TheGreatGrapeApe Champion.
Feb 18, 20, 0 50, It's all about the quality of the cables, if they're good enough to handle the signal then you're fine, if they suck then either one can fail, but they fail differently. It also depends on the type of signal and resolution. Dec 8, 2, 0 20, VGA is just older and basically outdated.
If you are considering getting a new monitor, there is no reason not to get DVI and it really cost no more. I hook up two PCs to it using the different connectors, and can use the monitor controls to toggle between PCs. The question you should be asking now is do you want a monitor with HDMI connector, to which I would reply that it would be good to have for future proofing even if not needed now - but some monitors just don't have one - especially the older models.
It seems that sometimes cables come with the monitor. Is this good? Or are you better off buying a third party cable for lots of money? The included cables are usually fine unless you're trying to run the monitor at distances greater than 9ft. You must log in or register to reply here.

However, these connector standards are rarely if ever found in PCs now for general-purpose personal use, most such applications having migrated to USB. When used as a monitor interface, a D-Sub port is also known as a VGA port, an analog connection standard that's been around for some time.
The connector is a DE connector with 15 pins in three rows, often referred to as a "mini-D-Sub pin" or "D-Sub pin" connector. Some connectors omit unused pins. D-Sub is currently the most widely used monitor interface, compatible with very large numbers of PCs and LCD monitors.
The DVI-A connector for analog use is not in general use and can be disregarded when choosing monitor products. Keep in mind that there are two types of mainstream DVI-D digital connections: single link and dual link. DVI-I, the other DVI standard, can be used with both digital and analog connections, depending on the monitor cable used.
Monitor cables with DVI-I connectors on both ends were available at one time. These are rare today, since this configuration made it difficult to determine whether the connection was digital or analog and generated frequent connection issues.
In such cases, the ideal configuration is a digital connection made with a DVI-D cable. All standards offer the capacity to transfer both audio and video signals digitally using a single cable; all offer easy cable attachment and removal.
The connectors lack screws, allowing the cables to be readily inserted and removed. The disadvantage: This makes it easier to dislodge a cable connection if a hand or foot catches on the cable. A technology intended to protect copyright on digital content, HDCP allows authorization of both output and input devices before video is displayed. Currently, however, this implementation appears to be imperfect: In certain cases, input and output devices are not completely compatible i.
Some products can transmit audio from the DVI side via a conversion adapter. HDMI was intended mainly for use as a digital video and audio interface for home electronics and AV equipment. The table below summarizes the major differences. There are significant differences in functions implemented between HDMI versions through version 1. Since HDMI versions are backward compatible, we can still input and output video and audio if the output side is compatible with version 1.
However, if the output device uses functions implemented in version 1. Incidentally, while HDMI 1. A version number such as 1. For this reason, even a product advertised as HDMI 1. Click to enlarge. However, there's no reason it can't also be used in AV equipment.
With a maximum transmission speed of However, unlike HDMI, which transmits data for RGB video signals and clock signals separately, it sends all video and audio to the destination device through a serial connection, split into micro-packets called transfer units. Since DisplayPort is a serial interface like PCI Express that generates a clock from the data instead of using external clock signals, data transmission speeds and functionality are easily improved.
In addition, since DisplayPort employs a configuration wherein the LCD monitor is operated directly, it makes it possible to reduce the numbers of components. Another benefit is its ability to transmit signals over distances of up to 15 meters.
In the DisplayPort standard, the output side is defined as the source device and the input side as the sync device. Under this configuration, the source and sync devices communicate with each other, making it possible to automatically adjust transmission to the optimal resolution, color depth, and refresh rate.
Audio and video data can be transmitted through a combination of single, double, or quadruple channels called lanes, and two data rates 1. The minimum configuration is a single lane at 1. The audio formats supported and other attributes are important elements of sync devices.
Other formats are optional. These licensing fees entail significant costs for manufacturers. When product pricing reflects these costs, they can impact ordinary users to a greater or lesser degree.
