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)

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..

Had been using a much more expensive 2 port splitter but needed more ports. Saw this and thought I would give it a shot. Worked so well I bought another. For the price it cant be beat. Definitely recommend.Nit picky issues;Having input in one side of unit and duplication ports on other is a tad klunky.Lights are a tad brightThere is a small "blip" when turning on a device that is attached thru extension port - but it lasts just a couple of seconds and then picture/sound is constant.

It's exactly what I needed and it works great!.My cable box's signal goes in and 4 identical signals come out.(Living Room TV, Bedroom TV (opposite side of the wall), Computer Monitor and DIGINOW Video Capture.)I said that it has a finite lifetime (now on my second) maybe because mine is powered on 24/7/365.It should work 1.5 to 2 years. I keep a 1 in/2 out splitter as an emergency spare.

Great product, easy to install, long cord came with it, no button to switch the input on it and lost the instructions so it’s hard to figure out. That’s my problem though, most likely

I used with HDMI over Double-CAT5 baluns to reach over 60 feet of wire length, and while the baluns all operate perfect on their own (even on 4K on the 30 foot run) none operate after this splitter. Ports 1, 3, and 4 have timing sync issues and severe green dot artifacting and only operate at resolutions under 1080P. Port #2 works at 1080P without artifacting but frequently loses sync and needs to be power cycled to resolve (unplugging & replugging the HDMI cables do not resolve this so it is definitely the splitter at fault).It's marginal at best if you're using it for CCTV, and absolute garbage for television unless you have HDMI 2.2 cables (rated for 48GB speeds or higher, or HDMI over Fiber Optic, but if this was the case you would not be obtaining a $15 splitter, you would be using the $220 or $499 splitter which I eventually had to purchase anyway after 3 failed attempts at "cheap" splitters).It does work flawlessly with short wire runs using 48GB+ cables

Ease of use!

I was a bit skeptical on the video quality that this would produce. I have this hooked to a pc then have 6’ 30’ and 50’ hdmi cables running to different monitors in a office building to display streaming tv services. The video quality is perfect on each monitor. I have run into issues in the past with other splitters where when I power on the pc it had trouble recognizing that a monitor was connected to that port and I had to leave the splitter unhooked on boot up then plug it in after the computer completely started up to get 1080 resolution. This one works perfect

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.
