There are several different specifications for HDMI and more will follow in the future. Each of the specifications provide for certain data rates and the higher the data rate, the higher the resolution can be. HDMI cables are also rated for different data rates. However, it is not quite as simple as picking a cable to match the data rate. Cables will attenuate the signals (make them weaker) over a distance. The longer the cable, the more the signal is attenuated. For a long cable, expect the overall diameter to be greater than a short cable as this will help to reduce the attenuation. If the signal attenuation is too great, the image will not be received. For short runs, up to 6 feet or 2 meters, the attenuation is unlikely to be enough to cause a problem, whatever the image resolution might be. The final test is to plug in the cable. If it works, it's good enough. If it doesn't, it's not good enough. It is worth mentioning that both the line driver in the video source and the line receiver at the input play an important part in the signal transmission. A good receiver will cope with a longer cable run than a poor one. To summarize, try the cable. If it displays a signal, then do no more - the cable is good enough.

What is HDMI in hdmi cable stand for?

HDMI (High-Definition Multimedia Interface) is a compact audio/video interface for transmitting uncompressed digital data


What is the need for hdmi?

HDMI (High-Definition Multimedia Interface) is a compact audio/video interface for transmitting uncompressed digital data in a single cable. HDMI supports, on a single cable, any video format including standard, enhanced, and high-definition video along with up to 8 channels of digital audio. ~abejschwartz


Can you connect a high definition television to a digital cable box with a high definition multimedia interface cable and a digital video recorder video cassette recorder with a component cable setup?

Yes and No.If I understand the question correctly, you want to connect your cable box to your HDTV via HDMI, your DVR via component cable (Red, Green and Blue RCA connectors), and your VCR via component cables. Your HDTV should accept various video inputs - HDMI, component, and composite (the yellow RCA connector). Most argue that the HDMI connection will provide the best quality video. Next in quality is component video. Last is composite video. Your cable box may or may not have an HDMI connection. If it does and you subcribe to HD channels from your cable provider, then definitely use HDMI to connect to the cable box. If you have another HDMI input available on your TV, then connect it to the DVR (if the DVR has the HDMI output). Your VCR will likely have to be connected via composite cable. It's a crappy signal but VCR don't provide a great signal to begin with. Most VCRs only offer a composite (at best) output, anyway.


Can you use composite cable for high definition?

No. There is no composite video standard for high definition. If a video signal is composite, then it is also standard definition. High definition television will normally need an HDMI connection. Although there are other HD interfaces, HDMI is the only one found on domestic equipment. Any other output on a DVD player or receiver is almost certain to be an SD output only.


Is HDMI better than vga?

HDMI and VGA are two interface standards for video signals. While the two are different, the quality of either of them is dependent on the source of the signal rather than the interface. Both are capable of carrying high definition signals. Indeed, VGA is used for higher resolutions that HDMI currently handles. HDMI is digital while VGA is analog. Although HDMI cables have restriction on length, the image quality will not degrade over a long cable run (subject to the maximum cable lengths). VGA signals can become degraded over long distances, showing up as smeared vertical edges on the display. HDMI carries audio data as well as video, so one cable does the job of a VGA and audio cable combined. It is worth noting that DVI is the digital standard for computer displays. DVI is fully compatible with HDMI video but it does not carry audio so it is a much closer equivalent to VGA. HDMI is becoming the standard for all commercial HD video content. It is getting almost impossible to purchase equipment that outputs any form of HD video on VGA or on analog component signals.

What kind of HDMI cable would you need for a Toshiba laptop and a vizio HDTV?

Any HDMI cable that has an HDMI logo will work. All HDMI products need to be tested and licensed by the HDMI organization. If a cable passes the test, it works. If HDMI cables work, they work as well as ANY other HDMI cable. The digital nature of the signal means that high cost cables do not deliver a better quality image than low cost cables. So, select the lowest cost cable in the store - it will be every bit as good as the most expensive.
