Question: I need to know how this works?  which plugs into the tv or what?  Thank you.  Just want to make sure it does what i need it to.
Document: This works very well as far as allowing three devices to connect through one HDMI port. The only issue is that if one of your devices is an &#34;always on&#34; type of device (e.g. Roku box), the automatic switching function will not work. All that means is you'll need to walk over to your television to manually change the input you want to watch. No real big issue, and definitely not one worth returning the thing over. I'm happy with it, and now have all my devices connected without having to reach behind the television to change plugs in ports.
This switch does do the job that I needed, but there are some things you need to know before ordering. It does not automatically switch between sources you have to press a button to make it switch. Also, the pigtail is quite short. Because of the short pigtail the unit sets close to the HDMI port which is behind my TV. I had to couple it with a longer cable to gift it out from behind the TV. If I had read the description more carefully I would have known both of these things.
It is the perfect combination. Is cheap and work!!! I read other reviews and have my doubts, but now I know why people have problem with this multi switch. Only can have one equipment on at the same time. I have the dvd, xbox and ps3 connected and haven't had any problem. First you turn on what you want to see in your tv and then you change the source or video feed in your tv. If wanna change to other, turn off first the one in use and after that, turn on the other, then the switch will read a feed and change to it.
This product works exactly as advertised. If you're having difficulties with the auto-switch, you should check to make sure the product connected does not use electricity even when off, as that will mess up the auto-switch function.
Im sure this product works just fine but I didnt need to split my HDMI signal i needed to MIRROR 1 HDMI to 2 TV's.Eventually found a solution for the same price on amazon
I am using this to connect XBOX 360, PS3 and Apple TV. Its a good quality device and works as expected. Only thing I wish it would have had was a longer cable. It gets kind of heavy (with three HDMI cables coming in) and hangs from TV's HDMI Input as it has got short extension length. I have to provide support to this switch just to make sure it does not break TV input. But I am sure there must be a reason behind designing this Pigtail switch with short length extension cable.
Just what I needed! It's very strong and sturdy. Just make sure you do not turn the other devices on whole another is on. It might or might not interrupt what you're doing but it doesn't hurt it or anything. But then again I have 4 different devices hooked up using it.
Works well, I bought a chromecast that did not fit well in my tv because of the length and wanted to also use my blue ray player in the same hdmi. The only downside is the plugs are too close and you can't really plug in 3 devices
Works, but is noisy... that is, it induces pixel noise on the display screen, not so bad that it is not unusable, but very distracting. It will automatically switch to the active channel if only one channel is active. Otherwise you must push the button. Actually, this is good since with 2 channels active it cannot know which one you want. I am keeping this switch because I use it to troubleshoot multiple machines. When  I am really using my machine for real work or streaming a video the noise is bad enough that I disconnect it.
I had a simple need: I have multiple HDMI sources but only 1 HDMI input. I have a 22&#34; 1080p HD TV screen that serves as my computer screen, and it works fine. But I've had nothing but headaches playing BluRay movies through my computer's bluray drive. I'm using VLC player which has BluRay disc capabilities, but it's limited and requires some know-how to play a movie, if it'll play at all. I also had a spare LG BluRay player laying around.So, this simple 3-Port HDMI switch was a perfect fit for my needs.
Answer: The single end plugs into the hdmi port on your tv and expands your hdmi ports from 1 to 3. It is helpful if your tv only has 1 hdmi port and you are in need of more than 1.
