This HDMI splitter lets you use multiple screens with one HDMI source. Are you interested in using multiple HDMI sources with one HDMI screen? Check out our very own 3x1 HDMI switch.

This reliable HDMI splitter will take any HDMI signal (rev 1.4) and duplicate the signal, sending the same high definition signal to 2 displays simultaneously.

HDMI Splitter Diagram

If you have a 1080p TV and a 720p TV, the signal sent to both from the splitter will end up being 720p unless you use a downscaler between the splitter and the 720p TV. That way, each TV will display the highest possible resolution.

100 Ft. Distance Test with this Splitter

In the video below we show off the distance limitations of our HDMI cable and HDMI splitter using 50 feet of cable between the splitter and the video source, and 50 feet between the splitter and the display (typical HDMI specs limit the signal to 16 feet only).

Splitters vs. Switches

This HDMI splitter will duplicate a single HDMI source on two HDMI displays. This is also sometimes called mirroring. Both displays will show the same video and audio simultaneously, whereas an HDMI switch is very different. A switch on the other hand will take multiple sources and allow you to choose which single source will be displayed on the TV. Watch this quick video to learn about the difference between the two.

HDCP Support

Perhaps one of the most important features of a high quality HDMI splitter is HDCP support. HDCP (High Definition Content Protection) not only protects the content from being pirated, but ensures that the content makes it unaltered to the display as long as the rest of your hardware is set up properly.

NOTE: Does not work with HDCP 2.2

High Quality Construction

Wire gauges and the high quality construction of this splitter allows for an operating frequency of 225MHz. HDMI 1.3b and 1440p resolutions are supported, future proofing you from many years of future HDMI development. The heavy-duty cool metal enclosure protects the insides and keeps the unit cool by aiding in quick heat absorption and dissipation.

Audio Split Issue

Egg - 12/29/2010 7:17:28 AM

7 found this review helpful

Pros: Works as advertised! Picture on both TV's is perfect. One has a 50 foot HDMI cable running to it and works fine! Lowest price for this type of product I could find. "Best Buy" version is $99.00 !!!

Cons: The specs discuss the splitter will split the signal based on the lowest resolution TV connected to it. This was not an issue for me seeing both TV's were 1080P capable. The problem I had was the audio side of the signal. I have a 5.1 Surround Receiver connected to one side and just a TV (just 2 speakers) connected to the other. If the splitter sent the 5.1 audio to the TV then I received no audio on the TV without surround. If I switched it around and sent the 2.0 audio, I received audio on the TV but lost 5.1 surround on the receiver. So, the splitter had to be set up to split the 2.0 audio signal and not the 5.1. The only other issue I have is the very bright LED's!

Other: Not a big deal, fortunately I was able to use another 5.1 connection from the cable box to the receiver so I can enjoy 5.1 surround sound on the receiver and 2.0 audio on the other TV! Highly recommend this product.

Just ok......

Pros: Cheap and does work.

Cons: Will not work splitting cable box to 2 a/v receivers unless both receivers are on. Turn 1 off, pic goes blank.

Pros: Good, quality construction, compact, operates exactly as it's supposed to do at a great price.

Cons: Integrated onboard power supply would have been nice rather than the external one supplied. However, works well

Other: I would/will buy again. Highly recommend and Sewell shipping was very fast.

It did everything I expected it to do. It had a power supply, which allows you to not lose any signal strength. Very Good.........

See all 7 questions


What if my displays are different sizes?


The splitter will send the lowest common resolution to both displays. The splitter has to send the exact same signal to both displays, and defaults to the lowest common denominator so that both displays will work. That means if you have a 1080p television and a 720p television both will get a 720p signal from the splitter.

Do both displays need to be on at the same time?


No. Televisions will generally continue to send a standby signal even when they’re turned off. You can watch on either television, or both, without worrying about changing your setup.

Do both displays need to be televisions?


No. This HDMI splitter works with any HDMI device. That means it will work just fine with televisions, projectors, AVRs, video processors, capture cards, etc.
