How to get the best picture quality using HMDI

Here are some ways by which you can improve your picture quality using HMDI cables.

You should begin by checking the rear of your High-Definition television set. You will probably find more than one input jack labeled as HMDI. The HMDI cable can be attached at this socket. It is different from your usual A/V cables.

You then have to attach the HMDI cable to the HMDI output jack, which is situated at the back of your cable box. You should do the same if you have a Blu-ray player, DVD player or HD player. You should then attach the other end of the HMDI cable to HMDI input jack, which is situated on your TV set.

Switch on your TV set and keep pressing the input button until it receives the signal from the HMDI input jack. Select an aspect ratio, either 16:9 or 4:3, depending on the type of picture you want. After receiving the signal from the HMDI cable, adjust the picture quality to suit your viewing needs.

Follow these tips and enjoy a clear and amazing picture of the highest quality.

The different types of High Definition Multimedia Interface cables

HDMI technology was launched in 2002 and has revolutionised audiovisual entertainment all over the world. The interface is provided by the HDMI cable. This is the cable that transfers digital signals from one digital device to another.

The digital quality of the audiovisual signal when transferred via a HDMI cable is retained at the highest level. This is possible because the HDMI cable has 19 enclosed wires inside it and can support up to 8 audio channels at one time. These cables transmit digital information at speeds in excess of 10.2 gigabytes per second. This is twice the bandwidth required for transferring high quality audiovisual signals. Discussed here are some features of HDMI.

The outstanding features of HDMI cables

The five different types of HDMI cables available are standard HDMI, standard HDMI with Ethernet, Automotive HDMI, High speed HDMI and high speed HDMI with Ethernet.

The standard HDMI cable transmits 1080i and 720p video quality signals. It improves resolution by a great extent. The standard HDMI cable can be used for DVD players, satellite televisions and digital broadcasting. The Ethernet transmitter counterpart of the standard HDMI cable is used to share high definition internet signals.

Automotive HDMI cables are used for high performance internet transmission. They are made from highly specialised materials. Resolutions in excess of 1080p are best viewed using high speed HDMI cables. The high speed HDMI cable with Ethernet is the most advanced type of cable. It can support the highest resolutions along with 3D and allow the transmission and sharing of internet without an extra cable.

HDMI cables v1.3 – understanding the features and benefits

HDMI is an abbreviation for high definition multimedia interface. These cables help in the transfer of high quality audio and video without affecting overall quality.

Superiority over component video

HDMI cables offer many benefits over component video. Some of these include support for better contrast and colour saturation along with digital bit stream compatibility.

It should be noted that individual results may vary to a certain extent. However, cheap sources like DVD players might not be able to scale and process the HDMI signal as effectively as modern day Blu-ray players.

Long cable issues

There have been instances wherein the video quality has been affected due to the use of long HDMI cables. This is mainly because of the fact that long HDMI cables take a longer time to transmit data. However, recent updates and upgrades have enabled HDMI cables to transmit data without any issues in terms of the overall quality of the audio/video. Most HDMI cables now support resolutions up to 720p/1080i.

Will the use of HDMI v1.3 affect your PS3 or Xbox?

HDMI v1.3 was designed keeping in mind the specifications offered by the major games consoles – the PS3 and the Xbox 360. Modern HDMI cables are compatible with these games consoles and will not affect the quality of the audio or the video.

HDMI cables – next generation entertainment technology

HDMI is the latest technology in the world of entertainment systems. It stands for high definition multimedia interface. An HDMI cable allows transmission of data between audio and video devices in a digital format, which is superior to the previous analogue format. HDMI technology is finding its way into more and more of the home entertainment market.

The latest versions of plasma TVs, audio systems, home cinema systems and projectors possess HDMI sockets to allow for better audio and video quality.

Since their launch in 2003, HDMI cables have been adopted by a lot of consumers and used for various audio and video devices. HDMI cables are designed to ensure better sound and picture quality.

Benefits of using HDMI cables

HDMI cables today come in various specifications. The older technology used by entertainment systems such as SCART involved more steps when transmitting data as they translate analogue and digital signals. With every extra step, the quality of signal transmitted would be reduced, so the final result would be poor audio and/or video quality. With a new HDMI cable, data is transmitted uncompressed which results in the best quality possible.

Another notable feature of an HDMI cable is that it supports the latest 1080p video standard, so you can connect your TV to your computer with an HDMI cable for better quality.

The HDMI cable allows you to transmit as many as 8 channels via the same cable. So audio and video device connectivity is easier and there is less hassle with leads and cables.

HDMI cables – How do they work?

The HDMI (High Definition Multimedia Interface) is a port used to transmit direct digital signals to televisions or monitors. These signals are a combination of audio and video transmissions. One end of the cable is connected to an audio or video device, while the other end is connected to a television or monitor. HDMI cables provide high-end digital and audio signals with enhanced picture and sound quality. The popularity of HDMI cables has increased which has resulted in the demise of analogue and coaxial cables.

How does a HDMI cable work?

The HDMI cable has 19 pins into one single interface, of these the first 9 pins convert analogue transmission into digital signals. The next 3 pins in the cable send digital signals to data channels. The 10th and 12th pins regularise and synchronise data. The other wires perform various other functions, some power the HDMI interface while others ensure that there is uninterrupted communication between the sending device (DVD player) and the receiving device (Television).

The uses of HDMI cables

HDMI cables can be used on various devices to get great picture and sound quality. Here are some applications where HDMI cables can be used.

• Home theatre systems.

• Televisions

• Video Game Consoles (WII, Play Station, X-BOX)

• Desktop Computers and Projectors

• DVD Players and Blu-ray Discs

Using a HDMI cable on these devices enhances picture quality and gives the user a pleasurable video and gaming experience. It also enhances sound quality. HDMI cables can also transmit data faster than analogue cables.

A closer look at HDMI leads

HDMI is the abbreviation for high definition multimedia interface. These cables have the capacity to transmit 10 gigabytes of digital information per second. They are used to transmit digital audiovisual signals from their sources to our television screens.

What are HDMI leads?

HDMI leads are the most preferred form of connection for HD electronic devices. Most high definition devices are still manufactured to use scart leads, but these are increasingly being replaced by HDMI. HDMI leads ensure that you have fewer cables attached to the back of your television.

Most modern electronic devices have HDMI ports installed for connection. A HDMI cable looks similar to a USB lead. HDMI does not convert digital signals into analogue like other technologies. The key part of this technology is that it keeps the digital signal in its original form. It can support eight audio channels in one cable and the bandwidth is high enough to accommodate future upgrades of the same technology as well.

Other considerations for HDMI leads

HDMI cables are available to meet different specifications. Each HDMI cable type is made for accommodating different levels of digital data. Their prices also vary. Cheap HDMI cables might not necessarily serve your purpose as they may be adversely affected by RFI and EMI. Make sure you buy your HDMI cables from reputable dealers.
