How long can dvi run

It will support up to x at 60 Hz with at 8 bits per color at Refer to Figure 2 for a listing of the video and audio support. Curiously, both the DVI specification and the HDMI specification contain the same electrical performance requirements between the source and the sink, or receiver. So, how is it that HDMI connectivity is promoted to work at up to 75 feet 23 meters versus the nominal The answer is that the industry is learning how to make better cables for this type of interface technology.

Better cable manufacturing methods for precision shielded twisted pair cable coupled with consumer electronics volumes will make longer, low-cost HDMI cables a reality. Aside from the transmitter and receiver requirements where consistency should be straightforward, the cable becomes the largest variable affecting performance in the transmission system. These parameters are: intra-pair skew, with time differential between the two wires making up the pair itself, and inter-pair skew, with time differential between separate twisted pair lines within the cable assembly.

Figure 3 shows the skew time budget for all the components in a system transporting p TMDS video, including the cable. Note that the total allowable intra-pair skew is only 0. Inter-pair skew may not exceed 1. Another parameter of high importance is far-end crosstalk, or FEXT. With STP, this is normally very low, but significant care is required at the receiver termination point.

Typical inter-pair skew within a category 5 style cable is easily greater than 7. De-skewing data within networks is the burden of the data receiver. But, what about longer distances? Certainly, a better solution is needed than even what HDMI promises. Read on. Released in and mapped directly into the DVI, HDCP provides data security for the interface and, hopefully, arrests the piracy concerns of digital content providers.

The DDC is the existing link in the DVI where the source graphics system communicates with the display device to determine its resolution capabilities. An authorized HDMI device will contain secret key values along with a special identifier called the key selection vector, or KSV for short. Each time an HDMI device is connected in a system, a three-part authentication routine automatically occurs. First, shared values, or codes, between devices are exchanged; second, the KSV of each receiver is reported to the source; third, frame-by-frame ciphers are sent to the receivers that enable data decoding.

Referring to Figure 4, HDCP supports interconnection of devices via a hierarchy of sources, sinks, or receivers, and repeaters. All devices in an HDCP system communicate through a protocol designed to allow digital content to travel only to those devices which the source determines have the authorization to receive such content. The hierarchy supports only a limited number of repeaters and total devices.

While there are various types of HDMI connections regular, Mini, Micro , they are all subject to the same distance limits. However, types of HDMI connected to smaller devices like cell phones and tablets are generally only available in shorter lengths since those devices are usually left close to the TV or monitor they are connected to.

The quality of the cable will determine the maximum distance. In these instances, joining two cables together with a booster is the easiest course of action. Going past that limit can still provide an HD signal, but not necessarily a 4k one. If a booster is not enough, using a balun extender will allow ethernet cable to be used to extend the HDMI signal.

Different baluns have different maximum lengths so be sure to select one that works with your specific set-up. Internet Explorer will soon be unsupported on this site.

Speaker Wire - Various Speaker wire is a bit more complicated than other cables when it comes to distance limits. Video-Only Cables S-Video - feet; feet with extender S-video is an older type of connection, now considered obsolete. VGA - feet regular ; feet with extender VGA is an analog signal and will get weaker over longer distances.

Time to Get Organized with Cable Management. November We are dealing with cables every day, but do you know the maximum transmission distance of various cables?

The Ethernet cable is also a twisted pair cable, which has different transmission distances according to different specifications of the network cable. They can connect routers, switches, firewalls and more network devices. The network cable is transmitting network signals. If it exceeds the distance that the network cable itself can bear, the signal will be attenuated. In severe cases, the network signal will be interrupted. Category 5 and Category 6 are both meters, and the regular oxygen-free copper Category 6 wire can reach about meters.

If you want to increase the transmission distance, you can install a repeater between the two twisted pairs, and you can install a maximum of 4 cables. If 4 repeaters are installed to connect 5 network segments, the maximum transmission distance can reach m. The transmission distance of the Ethernet cable is limited, and can not solve the long-distance data transmission, then the optical fiber can be used for the long-distance transmission.

Optical fiber is always used with Optical modules, like Cisco Optics Modules. Optical fiber is divided into multi-mode and single-mode. The transmission distance of multi-mode is longer than network cable, but shorter than single-mode. In 10mbps and mbps Ethernet, multi-mode fiber can support up to meters of transmission distance;. In a 1GbpS gigabit network, the multimode fiber can support a transmission distance of up to meters;. Compared with multi-mode fiber, single-mode fiber can support longer transmission distance.
