HDMI Splitter 1 in 4 Out Full Ultra HD 4K 3D HDMI Splitter 1X4 Way Box Hub 1080P Distributor Cable for PS3/4 Fire Stick Xbox HDTV DVD Player Monitor Projectors

Bought a couple of these to power 7 screens in our local church, one of which was a 15M run, very impressed, they work a treat with zero dropouts. I don't know why someone said WiFi interferes with them, totally different frequencies and not radio anyway :-) They don't come with a power supply but no drama it's just a standard USB Micro as used on phone chargers, so easy to find.

This splitter is solid and seems to have good quality connectors so the cables stay put once plugged in. I cannot vouch for the 4K capability but I can say it works well at full HD. I used it to feed 3 different TVs/monitors one of which was via a 25 metre HDMI cable, and they all worked perfectly. It was powered using a generic USB power adaptor with 4 outlets all capable of supplying 2.5 amps. I am not sure what the current drawn by this unit is but I had it on for several hours without issue,

I purchased this HDMI Splitter 1 in 4 out with the intention of distributing my HDMI signal from my gaming console to four displays. While it did manage to split the signal, it introduced a catastrophic flaw: it severely disrupted the Wi-Fi signal of my gaming console. As a result, my wireless controllers and headsets became completely unresponsive, rendering the setup unusable. Even more disappointing, the splitter failed after barely 5 minutes of operation under normal conditions. A complete waste of money, do not make the same mistake I did.

These are quite handy as spares.

Plugged in and it doesn't work it only works with one HDMI

Using this to distribute HDMI signals from a raspberry pi project to to 3 screens. I am only using 1920 x 1080 so can't comment on the 4k or 8k capabilities. Works very well for the price. Only down side I have found is when the unit is powered off and then on again, sometimes (but not all) I have to unplug the HDMI connections and then plug them back in one at a time for it to work. It repeats the one input on all the 4 outputs. Powered by the raspberry Pi USB output. **UPDATE - have since found out that the HDMI converters I was using were causing the issue. Since changed, all good and no problems.

No issues - does exactly as required.

Connected it to my CCTV and now have 2 outputs going to wireless HDMI extenders, so can view the CCTV in different monitors around the house. Easy plug and go setup and works great
