Many people ask me: "Does it really
matter what kind of video cable I use in my home theater system? Aren't they all
basically the same?" And to that I reply, "If you want a great
picture, it definitely matters which cables you use. Let me show you the
difference."
The reason to have a home theater system is to
recreate the movie theater experience in your living room. Whether you're
watching a classic 1950's flick or the latest blockbuster, it is critical to the
home theater experience to maintain the high-resolution picture quality of the
original film. You've probably bought the best VCR, the best DVD player and the
best video monitor your home theater budget would allow, but in order for them
to perform to their fullest potential, they need to be hooked up with video
cables capable of equal performance. With recent advances in video technology
and the clarity of today's sophisticated television monitors, high quality video
cable is an absolute necessity for recreating the theater experience in your
home.
There are many outside influences beyond your
control that determine picture quality, such as the strength of the broadcast
signal or quality of video transfer. By using high quality components and cables
you can help ensure the best possible picture.
The Visibility Factor
You can spot a cheap video cable problem a mile
away. Have you ever played with the cables behind your TV monitor or component
stack to get rid of "snow" on your screen? That's a clear sign that
you've got cheap video cables. Or, if you've ever bent a generic video cable
around a corner, you probably noticed that the sharpness of your TV picture took
a nosedive. More cheap cable.
Look at the comparison chart below. In this
head-to-head test conducted with sophisticated lab equipment, You can see that
some video cables, even so-called high performance, expensive cables, don't come
close to carrying the signal in its original form. Selecting the
"right" video cable is crucial to achieving maximum picture
performance.
Many different things including outside
interference, signal degradation and internal cable reflections often affect the
video picture on your TV screen. Cables play an important role in keeping these
problems out of your picture. The connections going between your video
components and your A/V receiver and from your receiver to your TV monitor are
critical to a "home theater quality" visual experience and require the
proper selection and set-up of those cables.
Video signals travel at much higher frequencies
than audio, and are therefore more prone to cable signal loss, resulting in poor
color saturation and phase accuracy. Picture "ghosting" can be caused
by cable reflections that occur when cable is poorly manufactured or bent. Snow,
spots, and other outside interference often pollute the picture when your video
cables are not shielded properly.
Cable Tips For a Great Picture:
- Keep video cable lengths short. The less
distance signal has to travel, the less loss will occur, keeping your
picture vivid and sharp. Sometimes you can't avoid a long cable run. Monster
Video Series 3 cable is designed to carry the signal over these runs with
the lowest loss.
- Don't bunch up excess wire, and keep all cable
runs away from AC electrical cords. Both situations can produce increased
picture interference.
- Avoid sharp bends and kinks in your video
cables to help minimize signal loss and ghosting. Use the best possible
signal splitters for your cable TV or antenna system. Poor quality splitters
are a prime source of signal loss and noise.
Movie-Quality Video Cable: What to Look For
- Full coverage braid plus 5.0 MHz bonded foil
shielding. A necessity for rejecting video noise and interference for
greater picture detail.
- Ultra-wide bandwidth capacity. For optimum
performance with the technologies of today, including baseband video and
extended bandwidth cable TV - and tomorrow, like High Definition TV and
Digital Broadcast Systems.
- Precision 75-Ohm, heavy gauge construction. A
video cable must maintain 75-Ohm impedance throughout to ensure a clear,
sharp, high-resolution picture without creating ghosting or phase delays.
- High conductivity and low dielectric constant.
High purity metals like oxygen-free copper, carefully extruded within the
proper dielectrics, are important for accelerated signal transfer and
greater phase accuracy, which ensure naturally vivid, accurate color.
- 24K gold plated precision connectors. A cable
is only as good as its connection. Not only do 24K gold plated precision
connectors ensure the best video signal transfer for enhanced video
performance, they provide a long lasting connection that won't corrode over
time or become loose from fatigue.
- Durable, flexible cable jacket. A high quality
cable jacket protects its contents from temperature extremes, moisture,
etc., yet should be flexible for easy installation.
Hooking up your home theater with high quality
video cables lets you see movies the way they were meant to be seen. With the
proper components and cables, you'll be wincing at fiery explosions, warding off
enemy attacks and wandering through lush green jungles as if you were really
there. And isn't that what home theater is all about? |
