You can have a satellite receiver, Blu-ray or DVD player, a laptop PC and several gaming consoles connected to your HDTV's HDMI ports. The number of devices with HDMI connections is growing all the time, and some HDTVs don't have enough ports to go around. If your HDTV is short on HDMI ports, help is available in the form of an HDMI Switcher adapter. You plug your HDMI devices into the input ports on the adapter, and plug the output port into the HDMI input on your TV. This way you can turn one HDMI port into four or more.
1. Count how many HDMI devices you have and compare the number of devices to the number of HDMI ports on your TV. Most HDTVs with HDMI ports have at least two. Some have four. If you have four HDMI devices, and your TV only has two HDMI ports, you need a switch adapter with at least three HDMI ports. Remember, one of the ports on the TV will be taken up by the input from the adapter.
2. Consider which features you need. Some people are happy with getting up to press a button on the switch adapter every time they want to change HDMI sources. Others demand a switch adapter with a remote control or feature that switches inputs automatically when they turn the device on.
3. Compare prices and features on different models. Make sure the switch you choose is compatible with the HDMI 1.3 standard if your HDTV is 2D. If you have a 3D HDTV, make sure it is version 1.4 compatible. You don't want to spend more than you have to, but reliability and image quality degradation can be a problem on cheaper switches. Read reviews on the models you are interested in.
4. Verify you have enough HDMI cables to go around, and that the cables are long enough. Some switch adapters come with very short Cable HDMI, so you may need to purchase more cables.
