Generally speaking, your computer is going to have one of two outputs: either a standard SVGA output. traditionally used to connect to a computer monitor, or, on higher-end machines, a DVI output.

uter is great. Wouldn’t it be better if you could use your new 42″ HDTV as a display instead of your little 17″ computer monitor? Its difficult to resist that urge, but connecting a computer to a TV isn’t always as easy as you might hope. In fact, “How can I connect my computer to my television” is one of the most common questions we receive on our technical support lines. Sometimes, it can be as simple as a single cable, but more often than not, connecting these two devices requires a converter box. In this article, we’ll look at all the options for connecting a PC to a television.

Computers with a VGA output

Assuming your computer has a VGA input, then the easiest connection is if your TV also has a PC VGA input. This would be the standard VGA video output from a computer to the same connection on a TV. Many newer televisions, in particular HDTV’s, have this connection. If your TV does have this input, then a simple Super VGA cable (male to male) will do the trick, and will give you the best possible video quality.

If your television does not have a VGA input, your next best bet is if the television has a component video input. If so, a converter box is available (our part number 40H1-50200) that will convert your VGA signal into Component video. (Note that this part only works in one direction; if you needed to convert component video back to VGA, you would want part number 40H1-50300). Component video gives you the same high quality picture as VGA, so it’s the next best choice after VGA for converting a computer signal. (The other two video options we list below, composite video and s-video, will not deliver as clean a picture, and should only be used when neither VGA nor component video are available.)more on www.worldofcables.com

VGA to Component Converter

Converting VGA to component video often causes confusion for customers, who wonder why a converter box is needed. This confusion is because there is also a cable out there that looks as though it would do the same job as the VGA to component video conversion box. VGA to component video cables, such as the one shown to the right, are often mistakenly purchased in an attempt to connect a computer’s VGA source to a component video display.

VGA to component cable

The reason why this cable will not work to convert a computer’s VGA signal into component video is because the VGA signal and component video signal are very different video signal types. It takes more than a simple cable to convert between the two. This cable is actually designed for use with certain projectors that have a 15-pin VGA connection that is specially designed to be capable of accepting the component video signal (often referred to as a Y/Pb/Pr signal). This design is so that the projector doesn’t have to have separate jacks for both component video and VGA, thus saving space (and money). This same dual-purpose connector is also found on certain HDTV set-top boxes.

If you have an older television set that has neither a VGA nor a component video input, then it will most likely have a composite video (yellow RCA jack) and / or an S-video connection. To convert your VGA into Composite video or S-video, our part number 41CV-50220 will do the trick. This box gives you the option of converting your computer’s VGA signal into either Composite or S-video. It also has an additional VGA output if you would like to have a VGA monitor and your TV hooked up at the same time. More on www.worldofcables.com

Computers with a DVI output

Any new HDTV out recently will have a DVI or HDMI input on it as its digital connection. If this is the case for you, connecting your PC to the television is simply a matter of choosing either a DVI cable (if your TV has a DVI input port on it) or a DVI to HDMI cable (if your TV has an HDMI port on it).

So what do you do if your television is not equipped with DVI or HDMI ports? Well, as it turns out, most computer video cards with DVI on them can be readily adapted to a VGA connection using a simple DVI to VGA adaptor to convert the DVI port into a VGA port. From there, you can simply follow the instructions above for connecting a VGA output to your TV. More on www.worldofcables.com

What about Audio?

All of the options listed above are for video signals only. Audio will have to be run separately. Fortunately, unlike the video hookup, connecting up audio between a computer and a TV is pretty straightforward. Computer sound cards have a 3.5mm (sometimes also referred to as a 1/8 inch) connection. This is the same connection you would find on headphones or computer speakers. That signal is easily converted to a 2 RCA (Red and White) stereo connection, which can be plugged into the back of your TV, or the back of your receiver if you have one. Worldofcables offers two versions of this cable, depending on your needs; our standard quality and premium quality 3.5mm to two RCA cables are shown in the pictures on the right.

HD TV has to be one of the coolest technological improvements since the advent of pineapple lumps. High definition video is crisp, sharp and so detailed it can border on appearing three-dimensional. With HD, watching the telly is almost akin to being at the cinema. Unfortunately, HD video has a dark side.

If like many, you’ve just purchased a shiny new piece of consumer electronic goodness, chances are that you’ve also gone into fiscal-induced shock trauma after finding out how much of your hard earned cash you’re probably going to have to fork out to get a “premium” HDMI cable so you can hook it up to your LCD or plasma TV.

Whilst many gadget buyers not in the know have felt the pain but chosen to buy a “premium” the HDMI cable anyway, many are appalled that the HDMI scam has continued for so long.

Don’t get me wrong, connecting any one of the growing number of AV appliances available with HDMI is a complete no brainer.

Previous generations of AV gear used SCART, component, composite or S-Video connections.

These were analogue, which meant that a percentage of the signal was lost or distorted before it got to your TV, resulting in less detailed video being displayed. HDMI which stands for “High Definition Multimedia Interface,” not only delivers video signals as a digital stream, giving you sharp and crispy video, it can also deliver digital audio and allow for two way communication between HDMI connected appliances (so for instance, your Sony TV remote will also work with your Sony DVD player), greatly reducing cable clutter and simplifying your AV stack in the process.

Unfortunately, there’s a whole lot of confusion and mis-information out there about HDMI as well as a lot of misinformed individuals who’ll try to sell unsuspecting buyers grossly over priced HDMI cables.

A quick check online revealed the extent of the HDMI scam. One online retailer had a 2 metre HDMI cable priced a breathtaking $180. Further searching revealed what appeared to be the identical HDMI cable (with a different brand) for a mere $40. In the interests of remaining litigation-free I won’t name any brands or retailers.

Making matters worse many retail sales people haven’t boned up on HDMI. Visiting one large retailer I was appalled to overhear a sales person telling a customer that they’d need to buy a $110 “Premium” HDMI cable so the Blu-ray player they’d just purchased could playback HD content at 1080p resolution on their Samsung LCD TV.

Here are some pointers for any wannabe HDMI cable buyers.

It’s digital

Assuming that like most typical home AV setups,. the customer’s Blu-ray player is a maximum of 1 to 1.5 metres from their flat panel TV, an ultra budget HDMI cable would not only also be capable of delivering 1080P HD content, it’d also deliver the video quality identical to that delivered by the so-called “premium cable”.

By-Sachin(Santa Clara, California)There are many experts who can easily take care of the HDMI cable communication technology and products. If some information needs to be gathered, you can easily learn about indor HDMI cable, outdoor HDMI cable and outdoor armored fiber.

The HDMI cable can be used to carry video, audio, and device-controlling signals (CEC). HDMI cables are often more expensive than other video cables at retail stores. However, many on-line retailers and auction sites offer HDMI cables at prices similar to coaxial and RCA cabling.The HDMI specification does not define a maximum cable length, but because of signal attenuation there is an upper limit to how long HDMI cables can be made. The length of the HDMI cable made depends on the construction quality and materials that were used. The signal attenuation and intersymbol interference which is caused by long cables can be compensated by using adaptive equalization.

HDMI has defined two categories of cables: Category first certified cables which have been tested at 74.5 MHz and Category second one certified cables which have been tested at 340 MHz to reduce the confusion about which cables support which video formats. A Category 1 HDMI cable will be marketed as a “Standard HDMI cable” and a Category 2 HDMI cable will be marketed as a “High Speed HDMI cable“. This labeling guideline for HDMI cables went into effect on Worldofcables. Category 1 and 2 cables can either meet the required parameter specifications for inter-pair skew, far-end crosstalk, attenuation, and differential impedance or they can meet the required non-equalized/equalized eye diagram requirements. A cheaply made cable of about 5 meters can be manufactured to Category 1 specifications using 28 AWG conductors.With better quality construction and materials including 24 AWG conductors, an HDMI cable can reach lengths of up to 15 meters .The HDMI website( Worldofcables.biz) has stated that many HDMI cables under 5 meters of length that were made before the HDMI specification can work as a Category 2 cable but cautions that only Category 2 tested cables are guaranteed to work. Long cable lengths can cause instability of HDCP and blinking on the screen due to the weakened DDC signal which HDCP requires. HDCP DDC signals must be multiplexed with TMDS video signals to be compliant with HDCP requirements for HDMI extenders based on a single Category 5/Category 6 cable.

Worldofcables LLC offer amplifiers, equalizers, and repeaters that can string several standard HDMI cables together. Having high mechanical strength, outdoor HDMI cable can endure high temperature variations. These cables are designed usually loose tube type so that the drawing force are applied on the cable sheath (cable jacket) and strength members without damaging the inside fibers and more type cables.

AdderLink X-DVI is a Breakthrough for Video Professionals

Adder, a leading developer of KVM switches, extenders and KVM over IP solutions, today announced the availability of the AdderLink X-DVI. The AdderLink X-DVI is the world’s first extender to send USB, DVI and DDC EDID signals over the same CAT6 cable. What’s more, Adder’s DVI KVM solutions will be delivered at a price comparable to current professional analogue extension solutions.
The X-DVI is ideal for users that require superior, no compromise video quality. Industries such as medical imaging, broadcasting, digital signage, graphic design, drafting and animation need to be confident that what is shown on screen is exactly what the workstation intends. The only real way to achieve this is via a digital medium such as DVI. The AdderLink X-DVI will support the extension of USB keyboards and mice and no compromise DVI over distances up to 165 ft.
Adder has broken down some serious technological barriers with this product. The X-DVI achieves full frequency clock rate for single link DVI connections which means you can extend any resolution within the single link DVI range. As an example, resolutions of 1920×1200 @ 60Hz can be achieved without the need to reduce data, frequency or color depth in any way. To achieve bidirectional USB communication alongside full no compromise DVI and all across a single CAT 6 cable is quite remarkable, and something no other manufacturer has been able to achieve. Delivering this kind of quality and functionality at a price point more reminiscent of analogue extension devices is certain to raise some eyebrows, but for Adder, it’s all about devising the best way possible to solve a problem.
A true plug and play solution, the AdderLink X-DVI feeds back extended profile DDC EDID information from the screen so that the video card is always set up perfectly. The AdderLink X-DVI is fully flash upgradeable; future proofing the product and protecting the customer’s hardware investment. Furthermore, the X-DVI can be interface powered at the computer end avoiding the need for additional power sockets and reducing cable clutter. For video only applications, an optional power supply can also be purchased.
The AdderLink X-DVI is available through local distribution partners around the world. Additional product information can be found at http://adder.us/products/AdderLink_X_DVI.aspx. The AdderLink X-DVI will carry a list price of $795 USD.
