Here are some more information for Cables Dvi:

A DVI Extender is used to extend the distance a DVI display can be located from a DVI-based computer. It uses CAT 5 cables for connecting the input and output devices and delivers crisp, clear images with no loss of signal. High resolutions up to 1920x1200 are supported by these devices. A local transmitter is placed next to the video source and a receiver is placed next to the display device and the two are connected via UTP or STP cables. Since these devices transmit signals over the CAT5e cables, they not only are inexpensive but also eliminate the usual clutter associated with standard DVI cables.

This CAT5 DVI Extender is easy to use and install and works on the plug and play principle. They are available in a point to point version as well as 2, 4 and 8 port splitter units. Power adapters are included and are only required at the remote location. Many other varieties of this extender unit are also available on the market today including the single link DVI over fiber and DVI dual link fiber optic extender. While the former supports a resolution of 1080p/1900 x 1200, the latter supports up to 2560 x 1600 often seen and required in medical imaging environments. These single and dual link fiber products are capable of reaching even greater distances than the Cat5 units.

CAT5 DVI Extender unit also has the necessary CE, RoHS and FCC regulatory approvals and are compatible with all operating systems. They are equipped with LEDs which indicate the DVI activity and operate at a video amplifier bandwidth of 1.65 GHz. The point to point units have an input for one DVI-D connection while the splitter units include DVI video and stereo audio connections in addition to a local DVI port on the transmitter.

An ideal solution for a wide range of applications where the local image has to be displayed at one or more remote locations, the DVI Extender is used in call centers, airports, financial institutions, restaurants, hospitals, digital signage applications, exhibitions, trade shows, military and government facilities.

Where Would We Be Without HDMI Cables?!

We are all lucky enough in this day and age to have a multitude of electronic entertainment equipment in our homes. With prices dropping exponentially we now have HDTVs, DVDs, PlayStations, Digital Radios, and Satellite TV among others. The home theatre has been born and it is due to clever little inventions that we have this privilege. Before the HDMI cable we used to rely on the following connectors:

Component video cables- known to you and I as RCA connectors - these connectors carry video signals into two channels for colour and a third for luminance. Another connector is the S-video cable which transmits analogue signals using one cable and a four pin connector. Another is the DVI cable which is a 29 pin connection used for computer monitors which can also carry digital signals.

Many people who had HDTVs in the early stages relied on DVI for obvious reasons in that it hit the market first. Not to go into too much depth but the Digital Visual Interface (DVI) cable is a low cost, high-bandwidth digital connector which was originally used to connect PCs and digital monitors. It is now the most widely used connection in the computer industry. They can also be used for your home theatre system as you can use the DVI cable for connecting projectors, monitors and advanced DVD players.

However HDMI has made things a lot easier for us all. You can use these when you want to hook up a HDMI system with that of a DVI. HDMI cables carry video, audio, and intercomponent operability commands (which are remote signals). When you connect up a HDMI with a HDMI cable (in particular the new HDMI 1.3) you get all the video performance that DVI has to offer up to and including 1080p.

Further to this HDMI offer even more advantages as you can deliver digital HD video, multi-channel audio, and control signals between various HDMI and DVI components. SO HDMI offers a brilliant solution of combining many functions in one cable rather than having that annoying spaghetti of cables that you would normally expect (and hate) for you home theatre.

HDMI 1.3 also offers high data speed and supports a new special format known as Deep Colour which can support 1.8 times as many colours as RGB. HDMI 1.3 also offers improved audio syncing so you have no more annoying lip sync problems. On top of this, the HDMI 1.3 supports the output of Dolby TrueHD and DTS-FD Master Audio streams and can be used with can be used with a number of products, including the latest DVD players and the Playstation 3
So this is just a basic run down of what HDMI cables have to offer. They really do make having a home theatre that bit more manageable and also allows you to get the best out of it!

Is there a max contrast ratio for either dvi or vga cables?

Also, is there a min ms?

If you want more custom resolutions usually vga is the way.
DVI is higher def and faster and better quality -recommend
