The day of the analog device is waning. All-digital video components have on the market for several years, and nearly all newly manufactured electronics is digital. Most of us, however, don't have the time, money or inclination to always buy the latest and newest equipment. An HDMI switcher, which means High Definition Multimedia Interface switcher, can help bridge the gap between the older digital sets, and the growing number of new electronic devices using these connections.
Many HDTV sets were manufactured with a limited number of high-def inputs, which limits the number of devices that can be plugged in. Realistically, equipment manufactured two years ago probably works very well, and probably doesn't need to be replaced. A lot of older electronics, however, were designed before the home theater concept became so popular. When exciting new devices get released we often are convinced to buy them and add them to our systems, compounding the digital component population crisis.
If you are not really a tech-savvy type, how do you know when to buy this type of device? Just add up all the video components you want to play through the HDTV. Then examine the back and sides of the set and count the HDMI input ports. If you have never looked for them, they are easy to find, and usually are labeled. If you have more devices to plug in than input ports, it's time to get a switcher.
Once you have determined that you indeed do have the right inputs, but not enough of them, what should a consumer look for in a switcher? First of all, plan ahead for a future where there will very likely be even more uses for these ports. Maybe your old video game player works fine, but if it needs replacing, the new model will very likely connect via HDMI. The old standard DVD may still play adequately, and worked well with regular discs, but you might decide to go with a Blu-ray player instead.
This means that you will want a component with enough inputs to keep everyone happy now, and in the future. A good idea is to select one with at least two more ports than you think you might need. Kids grow, for example, and want the latest gaming devices. Better to to plan for expansion, instead of having to manually plug and unplug a device every time it is used. Remember, it is much less expensive to add inputs than to buy a new TV.
What should a consumer look for when it is time to buy? Make sure your new device is compatible with your current signal. Technically speaking, HD uses a 1080p video signal in combination with high definition audio. Look for a component with those specifications, and one that will perform well with your current equipment. If your standard is HDMI 1.3 capable, meaning it can handle the very latest developments, then make sure the your switcher matches that capability.
Your new switch should have a remote control and front lights indicating which devices are in use. This expedites any necessary troubleshooting. Be advised that sometimes there are compatibility issues with components. Some may work beautifully with a particular switch, but others won't. Save your receipts just in case you need to make an exchange. Cost of a new HDMI switcher is usually less than $200, and is well worth the money.
