Video Connectivity Products
DVIGear® is a leading supplier of Digital Connectivity Solutions for professional, commercial, and residential display applications. We have an extensive range of DVI and HDMI distribution products:
These electronic devices enable the connection of multiple PC and HDTV sources to one or more displays. Our switchers use fast, state-of-the-art digital signal switching and are rugged, reliable and extremely easy to use. Our switchers can be controlled using a front panel input selector, or via a convenient IR remote control. Other advanced models provide switching via an RS-232 serial control port or a LAN port.
Some applications require a single PC or HDTV source to be routed to many displays. DVIGear’s range of HDMI and DVI splitters (distribution amplifiers) deliver the perfect combination of high performance and ease-of-use. A variety of models are available for PC and HDTV signal distribution applications.
In the digital world, the number one signal quality problem is excessive jitter. Jitter can be caused by a wide range of factors and every component in the digital signal chain adds a certain amount of jitter to the signal. In complex systems the resulting aggregate jitter can make the signal unusable. To solve this problem, the digital signal must be fully “re-clocked” using a digital repeater. These devices receive, de-serialize, buffer, re-serialize and then re-transmit the digital signal. In doing so they can make a significant reduction in signal jitter and other degenerative effects intrinsic in long cables runs. Repeaters can be used at the source side of long cable run to “clean-up” a noisy transmitter. They can be used at the display side end of long cable, and they can be used in the middle of two long cables for increased range. Unlike many competitive units, DVIGear’s range of DVI and HDMI Splitter / Repeaters fully re-clock the input signal, and offer independent re-clocked outputs.
Copper Cable Extenders http://www.dvigear.com/extenders.html
There are many challenges to overcome when designing systems that require long DVI / HDMI cable runs. These high-speed serial data formats operate at 10x (or higher) bit rates than corresponding analog signals. The bit rates of these digital signals increase in direct proportion to their resolution and color depth. As cable length increases, moving these high-speed bits over copper cables becomes increasingly difficult due to a variety of factors including: cable capacitance, inter-pair and intra-pair skew, crosstalk, differential impedance errors, group delay errors, etc.
In order to achieve successful digital cable runs, it is essential to use high-performance cables where these factors are minimized to the greatest extent possible. This especially true with longer cables >50 ft. (15 meters) because these degenerative effects become worse as cable length increases. Improvements in cable range are also possible using copper cable extender technologies, for which there are two (2) basic approaches: HDBaseT™ Extenders and Active Cable Extenders (ACE™).
DVIGear offers a wide range of copper cable extender solutions that utilize a variety of copper cable mediums, including: DVI/HDMI cables, CAT‑X category cables and coaxial cables. Each type of extender offers certain advantages for different applications and budgets. In most cases, these extenders utilize two elements:
Transmitter Unit – accepts an input signal from the source device and conditions it for transport over the intended copper cable medium.
Receiver Unit – receives the signal from the Transmitter Unit and converts the signal to the intended output format for display or routing further downstream in the signal chain.
The most common type of extender technology is the active cable equalizer. Long cables suffer from high levels of insertion losses caused by cable capacitance. When insertion losses become too high, the cable will introduce an excessive amount of jitter (known as additive jitter) to the digital signal, which can severely degrade the cable’s performance. A cable equalizer can help mitigate insertion losses by restoring high frequency components of the digital signal; at the same time this reduces jitter to acceptable levels. Today, nearly all modern displays have a certain level of cable equalization on their DVI and HDMI inputs; however, in most cases, the amount of equalization is only enough for cable lengths up to 65 ft. (~ 20 meters). DVIGear’s range of Active Cable Extenders (ACE™) provides sufficient range to equalize cable lengths of up to 200 ft. (~ 60 meters).
Optical Extenders: http://www.dvigear.com/optical-extenders.html
Some digital display applications can benefit from signal transport over fiber optic cables. This is especially true if cable distances greater than 50 meters (164 ft.) are required, or if the cables must be plenum rated, or detached and pulled through a narrow conduit. Optical cables also offer excellent immunity to environmental RFI/EMI fields and have a small electronic “footprint” in terms of radiated inference.
DVIGear offers a complete line of optical extenders that address the needs of diverse applications. These products support cables distances ranging from a few feet to several miles. DVIGear also offers several types of detachable optical cables, which can be custom ordered at any length desired.
Copper Cables: http://www.dvigear.com/cables1.html
DVIGear’s Super High Resolution (SHR™) Series cables are the definitive standard for long range transport of high resolution DVI and HDMI digital signals. Engineered for superior performance and durability, these cables support all DVI and HDMI resolutions with bit rates up to 2.25 Gbps at cable length of up to 60 meters (200 ft.). Their rock-solid performance and dependability have made these cables the leading choice of system integrators around the world.

Our long range active fiber optic cables feature integrated optical transceivers that support cable distances of up to 100 meters (328 ft.). For longer distances, our range of optical extenders can transverse distances of several miles and have provisions for detachable optical cables, which can be custom ordered with any length desired. Please contact us for more detailed information and a price quotation.
DVIGear’s HyperLight™ Series represents a new generation of advanced Active Optical Cables (AOC) that employ cutting edge technology to deliver unprecedented resolution, performance and value. Using plenum rated plastic optical fibers (POF), these cables are lightweight and flexible yet robust and durable.
Scalers / Converters: http://www.dvigear.com/scalers-converters.html
Converter/Scalers provide two essential functions. First, they convert the input signal from one format to another (e.g. analog VGA to digital HDMI). Second, they allow the user to select the resolution of the output signal for display on a flat screen display or projection system. In many cases the quality of the output signal from our Converter/Scalers will be better than what is possible using a direct input on the display because of the price/performance limitations of consumer scaling engines.
System Tools: http://www.dvigear.com/system-tools.html
