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)

Considering how inexpensive these are, they work awesome! I had to replace mine after about 4 or 5 years of constant 24/7 use on a 30 camera security system. It went out so i replaced it, and it's right back online! Considering how expensive some of these splitters can get this one works exactly the same for less than $20. When it does go out in 4 or 5 years I'll buy another and still my cost will be less than a lot of others.

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..

Nice splitter that seems to work fine so far. I used it to split tvs for the rock band video game and we didn't even have to adjust for any lag. I did notice that sometimes when you turn on a TV and one is already on, it shuts of for a second, almost like it has to adjust for more TVs, but it usually kicks right back on. Hopefully it keeps working fine. Only reason I took off a star is due to sturdiness. I found myself almost smashing the thing when I held it tightly to plug a HDMI cord in. And sometimes it seemed the HDMI port on the splitter would get pushed in a little when I plugged a cord in as well. So I just make sure to plug them in carefully from now on.

Great ship time. These products are easy to install and have fantastic picture quality. Very small but mighty!!

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 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

I got this to run anything on my Family room TV to 3 other remote TV's. The picture and sound is synced up on all 4 screens, the quality is good, as well. When you turn on each set the video feed is momentarily interrupted on the others for a second, but they sync right up. The other thing I found is most sound systems have a 20 microsecond delay. This causes a slight mismatch of the audio from one room to the other while standing in the cusp, once you get out of range of the sound system, you can't hear it. Or, you could just turn off the sound system and use the TV sound. I have one run 3ft, one 50ft., one 25ft, and one 15ft. If there is any lag on any of them, I cannot discern it. Now I can go room to room and not miss anything. I have had this item running for a few weeks, and it does exactly what I want it to do.

After 4 years it gave out without warning. The product wasn’t dropped or misused. It sat in the same place for all of its used. No warranty. Not sure how many years of use I was expecting out of it but not happy about it simply going out. It still has power but does to split the signal. I’ve tried several other HDMIs cables to rule that out but the common denominator is the actual splitter.
