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)

Exactly what I was needing. Works great!!

Ease of use!

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..

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

Purchased 1, it worked twice, then stopped working. Purchased 2 more thinking that might have been a defective unit, same behavior from all of them. These are garbage

My Dish receiver normally sends out SD signals to out other TV in the bedroom, and I still use that setup whenever we need to watch two different programs at the same time. But, when we are watching the same thing in both rooms, or just using the bedroom TV this splitter easily sends the HDMI signal out from the living room to the bedroom on the other side of the wall.The splitter is very easy to install. Plug an Play; no switches, setup or programming to mess with. The signal is 1080p and both TVs confirm that is what they are receiving. I do not see any signal degradation, delay, or choppiness on either TV, even when using both at the same time. The picture looks better on the living room TV only because it is a much newer 4K LED set that is better in every way compared to the 8 year old LCD TV in the bedroom.The case is metal. It is possible the bright LEDs on the splitter might be annoying in some settings, but my unit is on the back side of a display stand, and totally out of sight.I only have it hooked up to two TVs, so I cannot comment on how it performs when sending signals to 3 or 4 displays. None of my displays are 3D. I'll try to remember to update this, if there a problems, or if I get the chance to connect to more displays at the same time.

I recently built a new Windows 10 PC with dual monitors, and set the PC up at a new computer desk on the other side of the room from my old desk. But now my old desk was looking pretty empty and forlorn, so I decided to continue using it as an alternate computer desk by setting it up with a wireless mouse, wireless keyboard, and third monitor that I would split off the main monitor feed from the PC with a long HDMI cable.I bought this KELIIYO 1x4 splitter based solely on reviews. I connected my PC's HDMI output to the splitter, then ran a 6' HDMI cable to the main monitor at the new desk, and a 50' HDMI cable to the third monitor at the old desk across the room.Everything worked as soon as I plugged it all in. Both monitors being fed from the splitter are exactly in sync. There's no lag, and no discrepancy in brightness between the two monitors.The longevity of this product is yet to be determined, but based on how it is performing now, it's a solid five stars.

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.
