How Far You Can Run HDMI Cables

HDMI is no longer strange for us now; it is everywhere in your home, your HD TVs, HD media players, Set-Top Box, your HD displays, your HD cameras, your HD recorders and so on. We couldn’t ignore it in our daily life. Thus here comes the question, do you know what’s the maximum length you can run the HDMI cables? You might have no idea. Yes, most of us would never have thought about this question. However, there is the case that we need extend our HD devices to a longer distance, such as extend the HD signals of your HD media player from one room to another room, then do you know the max length you can go. So let’s check the case.

There are two categories of HDMI as defined by the HDMI organization, “standard HDMI cables” and “high speed HDMI cables”:

Standard (or “category 1″) HDMI cables have been tested to perform at speeds of 75Mhz or up to 2.25Gbps, which is the equivalent of a 720p/1080i signal.

High Speed (or “category 2″) HDMI cables have been tested to perform at speeds of 340Mhz or up to 10.2Gbps, which is the highest bandwidth currently available over an HDMI cable and can successfully handle 1080p signals including those at increased color depths and/or increased refresh rates from the Source. High-Speed cables are also able to accommodate higher resolution displays, such as WQXGA cinema monitors (resolution of 2560 x 1600).

The HDMI specification specifies required performance of a given cable, but does not govern the length as long as the cable meets the given requirements. So how far of an HDMI cable can you run from your video source to your television set? The professional technical support from VVdeals recommends 25 feet as a practical limit for their high speed cables to carry both a 1080p and 3D signal. After 25ft they are no longer certified for high speed. And with the longer distance increase, the quality for the videos would decrease.

Standard speed cables can carry 1080p but it depends on the device is why we only list them as 1080i/720p. Many newer devices though if all you want is 1080p can achieve that with standard speed cables, you only really need a standard speed cable if you are running both 3D and 1080p.

Then think of the “25 feet” as the magic barrier. So what to do if you need to go longer distances and insist on carrying a 1080p signal? All hope is not lost. You have a couple of options, including more HDMI cables and cat6 Ethernet cables. As HDMI cables are more expensive and the quality would decrease when the distance is longer. So Cat5e or cat6 network cables would be highly recommended. CAT6 ethernet cables which allow for runs up to a whopping 330 feet. You can use a HDMI network extender to transmit HD signals to a longer distance as long as you can. Of course, if you don’t like wires in a mess, a wireless HDMI extender would be an good option.

Anyway just make sure that your cable matches your application and that all specs are up to speed when you’re going for longer distance transmission.

USB 3.0: Something You Need To Know

What is USB and USB 3.0

Universal Serial Bus (USB) is an industry standard developed in the mid-1990s that defines the cables, connectors and communications protocols used in a bus for connection, communication and power supply between computers and electronic devices.

Within the past 14 years, the Universal Serial Bus (USB) has become the standard interface for connection of computer peripherals, such as keyboards, pointing devices, digital cameras, printers, portable media players, disk drives and network adapters to personal computers, both to communicate and to supply electric power. It has become commonplace on other devices, such as smartphones, PDAs and video game consoles.

The first official definition, USB 1.0, was introduced in 1996. It provides a Low-Speed transfer rate of 1.5 Mbits/s for sub-channel keyboards and mice, and a Full-Speed channel at 12 Mbits/s. USB 2.0, which came in 2001, made a leap to Hi-Speed transfer rates of up to 480 Mbits/s. In 2010, USB 3.0 has finally hit the market.

So what can you expect from USB 3.0 and how will it affect you?

What are the major USB 3.0 improvements?

In a nutshell, USB 3.0 promises the following:

  •  Higher transfer rates (up to 4.8Gbps)
  •  Full-duplex data transfers
  • Increased maximum bus power
  • New power management features
  •  Support for new transfer types
  •  Backward USB 2.0 compatibility
  •  New connectors and cables
  •  Support by Operating Systems: Mac OS X Mountain Lion and Windows 8 have been confirmed to support USB 3.0 natively whereas third party support for USB 3.0 is also widely available for Windows 7, Vista and XP. The Linux kernel has supported USB 3.0 since version 2.6.31, which was released in September 2009.

Where are those USB 3.0 products?

USB 3.0 silicon such as USB host controllers, peripheral chipsets and hubs compliant with the SuperSpeed bus have arrived in the latter half of 2009. Since then, an increasing number of consumer USB 3.0 products have appeared on the market, such as USB 3.0 Desktop Hard Drives, USB 3.0 Portable Hard Drives, USB 3.0 Monitors, USB 3.0 Adapter, USB 3.0 converter and so on. And in mid-June 2012 at WWDC, Apple finally introduced USB 3.0 to its entire line of MacBook Air and MacBook Pro.

Will my existing peripherals still work?

The good news is that USB 3.0 has been carefully planned from the start to peacefully co-exist with USB 2.0. That is, USB 3.0 is backwards compatible with USB 2.0. So whether you get a new USB 3.0 device or a new computer that supports USB 3.0, your old device will be able to communicate with the new interface. Naturally, it will do so at the old USB 2.0 speed. However, you won’t be able to use a USB 3.0 cable to connect a USB 2.0 device. So if your device has a USB 3.0 port, when connect to HDMI device, you will need to choose a USB 3.0 to HDMI adapter to get faster speed and best performance.
