As previously discussed, a passive splitter will technically mean a reduction in signal strength. However, for most uses where you are likely using shorter cables, this shouldn’t matter much. The reason lies in how digital audio and video signals work compared to their analog counterparts. Connect the display devices: Connect an HDMI cable between the first HDMI output on the splitter and your first display device (e.g., projector), then run another HDMI cable between the second output of the splitter and your second display device (e.g., television). But if you just want a splitter that's reported to work for mirroring your video, with a high probability of working, keep reading.

Now that you have both monitors hooked up, its time to set up how you want your monitors to display. The most common display Setting is to extend your monitor from your laptop or desktop screen, but when using dual monitors, many people will just use the two monitors instead of using their laptop. An HDMI cable has 19 wire pairs that terminate in the same number of pins on the HDMI plug. Each of these wires transmits different information electronically via digital signals. This includes not only audio and visual data but also information about the specific devices and commands you might find on a remote control. Why it made the cut: While there are plenty of simple USB-C-to-HDMI adapters out there, Targus’ USB-C delivers the best possible HDMI splitter performance and throws in plenty of ports to match. An HDMI splitter takes the HDMI signal from one source and splits it into two identical sources. HDMI splitters can either be passive, simply splitting the signal, or active, adding some additional power to the split signals to compensate for the loss of cutting a signal in half. On the other hand, an HDMI switch manages multiple source inputs to transmit to a single output (most receivers act like HDMI switches). Thus an HDMI splitter will transmit to all available channels while an HDMI switch will only transmit to one. How Does an HDMI Splitter Work?

Using an active HDMI splitter for longer cable runs should help eliminate this problem. However, if the problem persists, you may want to upgrade your HDMI cable to one that is better shielded, or another type like directional cables which we’ve talked about before. A shielded cable has an extra layer of material (usually a metal alloy or carbon allotrope) that deflects radio waves. Home Theater:recreate the multiplex theater experience in your home theater.

HDMI Version Support: Different HDMI versions support various features (e.g., HDMI 1.4 offers Audio Return Channel, and HDMI 2.0 enables 4K Ultra HD video resolutions). Make sure the splitter supports the HDMI version that meets your requirements. Warranty - When purchasing your HDMI splitter, it is advised that you choose a model with an extensive warranty such that your splitter is covered for a long time. In the event of any mishap, the warranty will cover repairs and even replacement if possible, helping you save money for other activities. Guarantees are placed on products as a means of the company standing behind their creation in confidence. Planning where the wires will go before buying some hardware helps make the installation process much more manageable. Although it’s something I forget all too often!

FAQ

EDID handshaking/HDCP: An HDMI splitter with EDID handshaking and HDCP compliance allows faster and more seamless operation. Ensure all devices in your setup, including the splitter, are HDCP compliant if you use copy-protected video content. A splitter with an EDID switch tells the screen which formats it supports, avoiding issues when playing specific video signals. Like we said, a lot of people, including manufacturers and retailers, play it fast and loose with A/V terms like “HDMI splitters.” Technically, HDMI splitters turn one HDMI signal into many identical HDMI signals. It’s HDMI end-to-end, and all they can do is mirror the screen.
