I wanted to put two inputs ( Sky Q UHD and an Apple 4K TV) into a Dolby Atmos Soundbar as the soundbar had only one input, this unit upgraded the bar to accommodate without any loss of Atmos, or 4K picture quality as my tv is older can could not pass the Atmos direct to Soundbar. It’s easy to fit and has the correct HDMI2.2 specification that I believe you need with an Apple 4K.The previous Sky box into TV then to sound bar was delaying the Audio and it was frustrating however by connecting directly the two mainly used inputs above to the Soundbar, this prevents any audio delay and it’s perfect because the cheaper switches don’t work with apple 4K or the Sky UHD as they are lost on some HDMI switches which have lower specifications. This was hard to find as so many items are out there for €40 + however this was delivered to Ireland for approx €22/€23 euro and it’s perfect to upgrade your one HDMI input Soundbar to keep the high quality Atmos and 4K picture intact.Excellent product and quick service by supplier 😄Edit * have a week now and had to turn off SDR and use HDR setting on Apple TV as it kept flickering after 5 days of use, that seemed to fix it so far

Great device, works perfect in 4k hdr pictures. Have it going between my ps5 and either my TV or my pc monitor on along cable tucked behind so if TV is in use can just switch it easily over to monitor and play.

I bought this so that my son could switch between his nintendo switch dock and the playstation without having to unplug something from the tv to plug in the one he wants to use. It was super easy to set up. Just plug the hdmi cords in and you are all set. Overall it works great. I would have preferred that the control for it slide left or right so you know which source it is currently set to, instead of the button pushing down and clicking into place and clicking it a second time to unselect it. But other than that it was an inexpensive way to fix our problem.

After months of removing and refitting cables decided to purchase this. Makes life so much easier and a very reasonable price. Click the button to toggle between the Switch and Roku stick. Time will tell if it last but so far so good

I can now toggle between Nowtv stick and Amazon fire stick on my TV. Picture quality brilliant. Great product. Many thanks to the person that responded to my question and sent me the link. Delighted!

When it works (which is only sometimes) this is not a splitter but a switcher. But even as a switcher it works only in one direction (1 in, 2 out) and is not bi-directional as advertised. More worryingly, however, is the fact that switching it doesn’t stop it send full power to the de-selected device, raising real concerns for safety. Like a fool I bought two: both are going back. Avoid.

used when run out of HDMI ports.

I use this splitter between my personal and work pc. It used to be a faff to unplug one plug the other then back again, now it's just one button. Super easy and makes my workflow much easier. It also has an automatic signal detection so I just shut one down and start the other it just flicks over which makes it that much easier. Recommend it with the caveat that this is the only splitter I ever tried.
