HDMl Video Wall Controller 2x2 4K, PORTTA Video Wall Processor with 11 Splicing Modes, RS232, 180° Rotate, Audio Extractor, 2x2,1x2,1x3,1x4,2x1,3x1x4x1, 4 tv Screens into 1 Wall Display

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 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

My cousin has an "old" monitor that only has a one HDMI input (and no DisplayPorts), meaning, if they wanted to connect both their PS5 and Gaming PC to the display, they'd have to manually switch the HDMI cables. As you can imagine, this gets frustrating quick. However, this HDMI Switch completely solved that and works perfectly. No drop-outs and a full pass-thru of the image. It's perfect.

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

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.

When I plug this into my Soundbar and then plug my Vero 4K+ and my Satellite receiver in the Vero 4K+ refused to boot unless the HDMI was unplugged. I also noticed the hard drive attached to the Vero 4K+ making a faint ticking sound even when the Vero 4K+ was turned off and unplugged from the mains (with no other USB powered devices plugged in to it). The Switcher box is obviously injecting power into the Vero 4K+ via the HDMI and causing it to malfunction / refuse to turn on.

The image outpubwas very blurry. Connected this to a 4K media player with 4x FHD images stitched together to create a 4k image. Then each output was connected to a FHD screen. It is blurry, so have ordered a Orei unit to replace it

Worked like a charm! If this is a replacement and you were using a firestick you will have to reprogram the firestick on the screens as well. Easy!

Buono. Funziona bene. Solo macchinoso per capire il funzionamento

Fait très bien son travail a un prix intéressant

Works great for the 4 split screen tv set up I put in my son’s room. Cheap alternative to the several hundred door set ups so the average family of 7 can afford nice things
