Question: It looks like some people have problems with the audio. I need to split both video and audio from a Comcast HD box to my Audio amplifier and the TV. Does anyone know if this box works, or there is a better splitter? Lots of thanks.
Document: I bought this to split the cablebox (Motorola HD box) to a Samsung 5000 series LED and a Panasonic 7000u HD projector. WOrks perfectly without any noticeable loss of signal.
I really wanted this inexpensive splitter to work, and it almost did. I split HDMI video from a TiVo Premier to two TVs: a Sony 32 inch and a Panasonic 50 inch, and the signal looked good. but the Panasonic 50 inch had issues with the audio feed through the split HDMI. no matter how I switched connections, the larger, more sophisticated TV would not register audio through the splitter. perhaps the amplification from the splitter rendered the audio signal unacceptable - I can't say.
I got this splitter after reading reviews that it works great and for people with similar setups. I got it to split my Dish/Direct TV to a single to my TV directly and one to my AV receiver. I couldn't get it to work at all with either device. I tried on another TV and setup. DIdn't work really there either. The unit itself felt ultra cheap. There's several of these with different names on Amazon, it's just OEM stuff and rebranded. I'm sending it back.
Hooked item and I works flawlessly could not have bought a better one and pic is perfect and no problems
It was just as I expected, merging two video games and my cable box through my TV. Hope this helps. I could have said I liked it in less than 20 words! I am going to stop leaving feedback.
I purchased this splitter to drive the signal to two different HDTV's. It worked right away with no adjustments on the TV settings. The two TV's were very different (manufacturer, size, etc.) and still had no problems.
I'm using it to split to a Samsung Smart TV and Projector. Works just fine. I'd recommend it if this is your requirement.
I bought this splitter to direct output from my laptop to a monitor and a large screen TV. It was cheap and simple, and it seemed to work fine. Then it suddenly stopped working, just beyond the 30-day window to return it. I noticed it got hot when plugged in, so I always made sure to unplug it when not in use. Didn't help. Save yourself the hassle and spend a little more on a better one. I just have to figure out which one to buy now.
I thought I was having a problem with my receiver because whenever I switched between devices the screen get would get scrambled Id have to turn off the TV to watch. I just removed the splitter and now everything works fine. I just realized I was past my return date so now I'm stuck with this.
This thing is pure junk. I'm using a Dell tablet with dock that has a single HDMI output.I need my monitor and projector to work. (duplicate screen)This thing lights up pretty blue LED lights.... and that's it. Tried only one at a time plugged into it and it still doesn't even do that. I remove this thing completely and try just the monitor and projector and guess what! It works! However, this thing doesn't do anything at all....
Answer: First question, why would you want to split the signal from your box in that way?  It would be better to run it direct from the box to the amp (i'm assuming its a receiver) to the tv so you are always using the speakers you paid for.Secondly, I have mine splitting my cable box (DISH) signal to my Xbox One and my Receiver (to take advantage of the Xbox one's "watch tv" functionality but still have the flexibility to use only the TV/receiver combo).  I have had no problems with video or audio issues.  This should do just what you need it to.
