VGA to HDMI Cables
It may seem like a good idea to buy a VGA to HDMI cable at first glance. But unfortunately, this is not the case. These cables simply don't work; they can't work. The solution that is needed to connect a computer to a high definition television is much more elaborate. A passive cable is unable to do the job so we need to look for a powered solution that can actively translate the signal.
The problem is that a VGA signal is analog, while an HDMI signal is digital. An analog to digital conversion requires an active process that evaluates each bit of information passed and translates it from its range of values to some combination of ones and zeros that can be understood by the receiving end of the HD cable.
HDMI Cable
The other problem that the conversion presents is that an HDMI cable carries both audio and video signals over the same wire. VGA only carries video signals. Even if we could use a cable to go between the two port types, our audio would get left behind at the computer station.
The real solution is probably to use what is called a VGA to HDMI converter box. The box accepts cables of both types (usually plus an audio input to accompany the video only signal from the computer) and converts the separate audio and video signals into one cohesive digital signal that can be carried by the HDMI cable. There is some loss of quality, but overall it's the best solution that really exists unless you can find different cable types to use.

The Changes In The New HDMI 1.3 Standard
Advancements in HD video are so fast that it can be somewhat dizzying. HDMI (High Definition Multimedia Interface) just recently became part of the mainstream HD A/V movement, but a new signal has already cropped up and is posed to replace the original HDMI specification. HDMI 1.3 was released in the summer of 2006 but has finally begun to take the place of HDMI.
Before one goes out and spends the farm on new HDMI 1.3 appliances, it is probably crucial to at least understand what the changes actually are, and if it's worth it. One of the biggest changes is the optional compliance to the new HD audio standards DTS HD and Dolby TrueHD. Original HDMI uses 7.1 surround sound audio for a slightly less real experience for true audio buffs. Another useful added feature is automatic audio/video sync, which ensures that the audio and video match up. I haven't had the problem yet where I felt like I needed this option.
HDMI Cable
Another feature which I'd like to perform a side-by-side analysis on is support of 30-bit, 36-bit, and 48-bit video with "Deep Color," essentially allowing for over billions of colors. The single link bandwidth is also increased to 10.2 Gbit/s on HDMI 1.3. Another feature that comes in handy for HD camcorder user is the availability of a mini-HDMI connector.
The main thing to keep in mind is that if you're going to get home theater equipment that is HDMI 1.3 compliant, you aren't going to be able to use those old HDMI cables and switches from your old set up. If you have multiple HDMI 1.3 sources and need to feed those to your display, you're going to need to get an HDMI 1.3 compliant switch. Same with the cables. So the choice is yours. You'll have to weigh the costs and benefits to decide.

Blu-ray DVD Player - How Do I Get This Best Video And Audio?
Blu-ray Players are all about getting stunningly, crisp and sharp images and great Superior Surround Sound for your movies. Nothing can rival the quality you get from playing a Blu-ray Disc. Streaming HD movies online maybe convenient, but they do not come close to the high quality images and sounds you get from a Blu-ray.
To obtain the absolutely best possible images from your player you need a HDTV and a HDMI cable which can support all the signals transferred from the player. The HDTV should be capable of full HD 1080p resolution. With an HDTV with 12-bit (color) display better color gradations. HDTV is also capable of dealing with his movies at 24 fps (frames per second). This is important, especially when watching Blu-ray motion pictures originally shown on a big screen theater.
HDMI Cable
Getting a High Speed HDMI Cable is the second thing you need to get the best possible image. High-Speed HDMI Cable provides thecorrect transmission of video signals. Monster Cable HDMI will certainly support all the video signals and give you the best quality. However, any high-speed HDMI cable is fine for most normal users. Produce the desired results and should have no problems with quality.
The real video signals are sent from the player, depending on how you set the player. (And of course content to use) the configuration of the player to get the best look is a stepsometimes forgotten. Just using a HDMI cable to communicate between your HDTV and player is not enough. You should switch on all available video features on your Blu-ray and HDTV to get the best picture. You need to select 1080p resolution for Blu-ray Discs and for up-scaling standard DVDs. 1080p/24 Hz should also be selected on your player and HDTV, as well as selecting 4:4:4 color space for Deep Color.
Getting stunning visual is just half the battle. Adding lossless surround sound adds a whole other element to your movies. Dolby® Digital True-HD and DTS®-HD Master Audio are two lossless audio formats and one of them should be selected when playing back Blu-ray Discs. Dolby® Digital True-HD and DTS®-HD Master Audio are High Definition multi-channel audio formats producing sound exactly as the original movie studios and sound engineers intended.
Setting up your player to default to one of these audio formats is the best way to go. If your Audio/Video receiver is capable of decoding these formats, you can take advantage of this and have the audio signal transferred via the HDMI cable. Blu-ray Players are capable of up to 7.1-ch surround sound. If your Audio/Video receiver does not have a HDMI input, most Blu-ray Players will have a 2.0-ch analog outputs. Some players even have 7.1-ch analog outputs for you to transfer the uncompressed sound to be decoded by you Audio/Video receiver. Making sure you can enjoy the best possible sound quality.

HDMI - A New Connection Standard For Home Cinema
HDMI is the latest connection type found on all new modern TV's, most modern Home Theatre amplifiers and many computer monitors. But why is it important to buy equipment with HDMI connections, and how much do you need to spend on HDMI cables?
HDMI stands for High Definition Multimedia Interface, and was designed to be a backwards-compatible replacement for the DVI interface commonly found on computer monitors. The standard called for a single cable that could carry a high-definition video stream, up to eight channels of digital audio and a single Consumer Electronics Control Signal. Its primary purpose was to become the standard connection between all consumer AV devices and computer displays. Today, all new projectors and televisions will come with at least one HDMI connection and usually more to receive hi-definition video.
HDMI Cable
Perhaps the most significant part of the HDMI specification is the support for HDCP, High-bandwidth Digital Copy Protection. HDCP-protected content such as Blu-Ray movies can only be decoded by licensed HDCP players, and any devices that connect to the player, must also be HDCP certified, or the player will only output a standard-definition signal. For this reason, when buying high-definition projectors, televisions or other devices, it's best to make sure they have HDMI connections and are HDCP certified.
Be careful when hooking up your home theatre system. It is not possible to have a HDMI connection to your amplifier, and then a component connection to your projector, as the HDCP protocol will prevent the player from sending a hi-def video signal due to the final connection not being via HDMI. It is possible, however, to connect your blu-ray player or cable box to your TV by HDMI and use a separate connection, such as a digital optical cable, to send audio to your amplifier.
HDMI carries both audio and video. This means only a single cable is required to connect a TV to your Blu-ray player or cable box. If you use a separate Home Theatre amplifier, then the player and cable box can first be connected to the amplifier, which is then connected by another HDMI cable to your TV. In this setup, the amplifier uses the audio channels and passes the video channel on to the TV. If you use the approach, look for a high-quality Home Theatre amplifier, with several HDMI inputs for all your sources, which also support HDCP.
Finally, a few words on buying HDMI cables. The prices of HDMI cables can vary enormously, with certain branded cables costing 10x the price of the same length unbranded cable. In practice, HDMI cable quality has very little impact on the quality of the audio and video transmitted through it. Unlike previous home video cable standards, HDMI is an all-digital connection, so the signals are much more resistant to interference and noise. For short cable lengths, almost any HDMI cable will be fine. Longer lengths can be more susceptible to connection dropouts due to HDCP signal loss, so consider spending a little extra on these, but keep away from the most expensive brands as they offer very little extra benefit.
