HDMI Splitter 1 in 4 Out V1.4b Powered HDMI Video Splitter with AC Adaptor Duplicate/Mirror Screen Monitor Supports Ultra HD 1080P 2K x4K@30Hz and 3D Resolutions (1 Input to 4 Outputs)

Why did you pick this product vs others?:Works great just as described. I have different sizes and resolutions of TVs connected and they all work fine.

Strongly Recommended!!I have tried for 3 of different adapters, and only this one works for my devices. Good price. Video understandable. easy to connect.

GREAT LITTLE ITEM WORKS WELL

Worked but at first made things a little fuzzy until played around with it. Used it to connect two TVs and video surveillance system.

If I could give a no star, I would. The power cord that plugs into the box is finicky. First one I got, figured something was loose and it affected it, went ahead a got a new one. Second one did the same thing but so much worse. You have to wiggle the power cord just right for it to register it is plugged it. Now, it just won't register at all. A pure waste of money and a great way to get angry over connectivity.

Exactly what I was needing. Works great!!

I've been using HDMI splitters for quite a few years. I bought this as a replacment for one that just quite working. I have AT&T U-Verse. I Video Recorder and 3 Satellites boxes. But I have 7 rooms with Flatscreen TV's in them. I use the Splitter to run relays from the line coming into the DVR. The HDMI coming out of the back of the DVR is used to plug into the INPUT of the Splitter. Then one HDMI cable for the Bedroom TV, one HDMI line runs out to the Music Room, and one HDMI line out to the Pool Room, and one HDMI into the bathroom. The Splitter comes with a 9 volt power adapter. These work very well. Picture and audio are clear on each set. All my TV's are Samsung's. Not that that would make any difference. But if you need a splitter, I would definitely purchase this one over the higher priced one. It's going to the exactly the same thing. In my case, having all the cables already run, it was 2 minutes hooking up. If you need cable, you can get any length you need right here on Amazon. You can run it through the ceiling or under the flooring if you have crawl space. Just bear in mind, whatever the Set Top box channel is set on, all the other TV's will get the same picture. Also, even if you play a DVD or Amazon prime on the Main TV, the only thing coming through that splitter will be what comes out of that Cable box, period. The other TVs can still be used for watching DVD's and Amazon prime, if they have the right connectivity. ie, Smart TV's or additional HDMI inputs for DVD input, ROKU, Firestick or whatever. But TV stations are dictated by the Motherbox. My Remote will actually let me change channels while I'm in one of the other rooms. Not sure how I got that lucky, but it does. And if you have Comcast, they have a remote with their Xfinity system that is made for doing just that.. You purchase it separately.. Anyway, hope this helps someone..

I used this to mirror a tv from one room to the other, it worked fine at first. I bought my first unit in early May of 2024 by the end of June I had to buy a second as the first one quit working. I figured it was my fault as I left it on 24/7. By the end of March 2025 the second one started acting up and finally going out. The second unit I hooked up so it was only powered on when the TV was powered on. It lasted a little longer, but now I am looking for something to last longer.
