What customers are saying

This HDMI splitter is generally viewed as a high-quality and reliable product that effectively duplicates an HDMI signal to two separate displays. The majority of users report that it works as expected, with no noticeable loss in picture or sound quality. Many appreciate the ease of setup and use, as well as the ability to power the splitter via USB. However, some note that it may not be suitable for extending displays or handling certain HDCP requirements.

    Splitter Rocks? Almost!

    Verified BuyerReviewed by - October 26, 2024

    [This review was collected as part of a promotion.] 3.5 stars. Advertized has HDR passthrough. Searched questions and answers, and supposedly, it does pass through HDR to include Dolby Vision. I added a projector to my setup, so I needed an HDMI splitter from my AVR to my OLED and Protector. My setup was Dolby vision compatible and worked properly displaying DV. Since introducing the splitter, I have now lost DV. Would give 5 stars if it worked as advertised

    Good product, user mistake

    Verified BuyerReviewed by - January 27, 2020

    [This review was collected as part of a promotion.] I purchased this product only a few days ago. The product itself works great, it was me that bought the wrong thing. I would like to point out that the product was sold to me in a very beaten up box and sold to me at the full price. Nothing on my receipt sad anything about the products box being damaged before my purchase.

    Bad image quality

    Verified BuyerReviewed by - August 12, 2025

    [This review was collected as part of a promotion.] When connecting only 1 screen works fine but 2 screens result in one of them loosing color quality, i discovered an $18 product that does this same thing but with good quality on amazon.

    Use with Nintendo Switch, but upgrage hdmi to 4k/8

    Verified BuyerReviewed by - December 25, 2021

    [This review was collected as part of a promotion.] To use this HDMI splitter you need hdmi cables with high speed capacity. Yes, hdmi have speed rating. You must use an hdmi cable rated at least 4k or higher. I used this to show my nintendo switch oled on 2 tvs. The cable provided with the nintendo was NOT powerful enough, so i used an 8k rated hdmi cable and the hdmi splitter worked. ALL the connected hdmi cables need to be high speed (4k or greater). This device works by taking 1 input (example a dvd player or game console) and splits the signal onto 2 tvs or monitors. This is Not for dual screen (where each screen acts independently). This just displays an image on 2 tvs.

    works great

    Verified BuyerReviewed by - September 14, 2018

    [This review was collected as part of a promotion.] I would recommend this if you need to send video/audio to 2 TV's. I just plugged in the HDMI cables, plugged it into the wall (needs power) and it was up and running. I am using it to "split" the output from a cable box to 2 TV's. I had tried this before using different products and they all failed due to HDCP compliance issues. As soon as I turned on the 2nd TV the signal would fail. No such issues with this product at all. 1st TV is only 3 foot away but 2nd TV has a 25 foot HDMI cable run into a soundbar and then to TV. Have experienced no drops or lag at all with either audio or video. I am only running 1080P so cant speak to whether it works with 4K or not.

    Please Read and Save Yourself the Headache!

    Verified BuyerReviewed by - November 1, 2021

    [This review was collected as part of a promotion.] Wow! Absolute garbage. I made sure to read all the product requirements before I purchased. I have my computer hooked to two different monitors. If I close a tab on the computer (mirrored to the two screens), it blanks to the pixelated rainbow! (picture attached). Then I have to reset it by unplugging and re-plugging the unit or HDMI cables. Even when It's working, It still blacks-out for 2-3 seconds every 15 minutes or so. Useless. Don't waste your money.

    Works perfectly!

    Verified BuyerReviewed by - June 10, 2023

    [This review was collected as part of a promotion.] This sounded too good to be true when I first came across this item, so I was a bit skeptical at first. I thought I would try it anyway. I wanted to be able to sync the TV at the back of the basement with the projector at the front so that when we were watching the big game nobody would miss a second of it. Once I got the HDMI cables in place, I fired it up. It took about 15 seconds for both outputs to finally show a picture, but once they did we were up and running. No lag at all between the two outputs, and no loss of quality on either of the outputs. I am overjoyed with the result. One tip: don’t cheap out on the HDMI cables. Purchase the high quality ones. It will make a difference.

    Working as designed, 24/7

    Reviewed by k - December 7, 2021

    At my workplace, we have a desktop PC running an information display (mostly text, in a web browser window) on a 55" 4K TV. The PC is outputting 4K resolution. We needed a duplicate of the screen mounted elsewhere nearby, so I bought this item to see how it would work. It has been performing as required non-stop, 24/7 for the last 9 months. Although not what we needed it for, I did test the stability of this setup using some 4K video, and everything was smooth with no noticeable degradation of quality. Solid product, definitely recommended. Price is right too; for 4K-capable products, there aren't many on the market that come in cheaper with reviews to suggest they're reliable products.

    Yes, I would recommend this to a friend.

    Works perfectly. See issue with Dolby Digital.

    Verified BuyerReviewed by - September 1, 2018

    [This review was collected as part of a promotion.] I had one out put connected to my receiver, the other to a 32 inch monitor that could only output stereo sound. When both were connected Dolby Digital didn't work on the receiver, only regular Dolby Surround. I need to unplug the HDMI cable to the monitor monitor to get Dolby Digital output from my receiver. Picture quality is excellent on both the 4K TV and the 32 inch monitor.
