With Avatar’s Blu-Ray discs having sold 2.6 million copies in the first two days, it appears that we have been in the HD era longer than we thought —- so long that some of the HDTV’s early adopters find themselves in a slightly awkward position today, as there are so many HD devices to be plugged in, yet so few HDMI ports on their HDTVs for these many devices.
Early HDTVs tend to have just about 1 or 2 HDMI ports, maybe because there used to be not that many HDMI devices around in the market.
In order to connect your many HDMI devices to your HDTV, one way, of course, is to upgrade to a new HDTV which nowadays usually has 4 or more HDMI ports, but that also results in significantly lighter weight of your wallet.
A more economic way is to use an HDMI switch.
If you have many HDMI devices that you want to hook up to your HDTV, but your HDTV has only 1 or 2 HDMI ports, this article will give some in-depth information on a 3 Port HDMI switch.
2. What is an HDMI switch (HDMI switcher, HDMI selector), and what does it do?
An HDMI switch (also known as HDMI switcher, HDMI selector) receives HDMI signals from multiple HDMI sources and sends the signals from one of them to your HDTV. This way, it serves as an agent to accept many HDMI signals for your HDTV, even if your HDTV has only 1 or 2 HDMI port(s).
You can connect multiple HD sources to your HDTV, such as your:
- Blu-Ray player, HD-DVD player, DVD player with HDMI output;
- PS3, Xbox360, Wii with HDMI output;
- HTPC, or computers with HDMI ports;
- HDTV box, satellite dish network, HDTV recorder;
- HD camera, or HD Cam recorder;
- Any other devices that are capable of outputting HDMI signals.
People have come up with all kinds of creative names for HDMI switches. The most common names are HDMI switch, HDMI switcher and HDMI selector; however, it is also popularly known as an HDMI hub, HDMI adapter, HDMI switchbox, sometimes even HDMI splitter (although HDMI splitter receives one signal and outputs to more than one HDTVs), or any combination of these words.
