What is an HDMI splitter?
An HDMI splitter is a device that allows you to connect multiple devices to a single HDMI output. This can be useful if you have a limited number of HDMI ports on your TV or receiver, or if you want to send the same video signal to multiple displays.
HDMI splitters can be either passive or active. Passive splitters rely on the video signal itself to power the splitting process, while active splitters use an external power source to amplify and repeat the signal. Active splitters are generally more reliable and can handle longer cable runs, but they are also more expensive.
Is it okay to use an HDMI splitter?
In general, it’s okay to use an HDMI splitter as long as you understand its limitations. HDMI splitters can be useful for simple applications such as sending the same video signal to multiple displays, but they may not work well for more complex setups. For example, if you’re trying to send a 4K signal to multiple displays, you may need a more advanced device such as an HDMI matrix or a video distribution amplifier.
It’s also important to check the specifications of the devices you’re trying to connect to make sure they are compatible with the splitter. Some devices may not work properly with an HDMI splitter, or may have specific requirements for the type of splitter used.
