HDMI 2.0 Splitter 1 in 2 Out 4K*2K Active Amplifier Support Full 3D HD 3840 x 2160 P HDMI Switch with HDMI Cable and USB Cable for Mac PC HDTV DVD DVR Xbox PS3 PS4

I received my item in less than 24hrs so that is what I call fast service! The unit is small - about the size of a matchbox (6.6cm x 5.0cm x 0.8cm). The packaging is minimal, simply a plastic blister pack with the unit & a 28cm USB power cable. The instructions is included together with the specifications. I do not have 4K so my results does not include any 4K tests. The USB power cable is used when extra power is required, and in my review I used 1m, 3m & 5m HDMI cables and no extra power supply was required.Connection setup was very easy. There's 1x HDMI INPUT with a RED LED on one side and on the opposite side there's 2x HDMI OUT with GREEN LEDs. Also, there's a microUSB power in next to the HDMI INPUT for when additional power is required. Connecting the cables is very simple, I used a BluRay player with 2x FHD TVs. The LEDs lights up, as I switched each device on, and the LEDs on the unit lights up to confirm a signal is received. I could not find any difference with the picture quality, with 2x TV output, 1xTV output & without using the unit. I repeated the tests multiple times using different cable lengths. There was no difference in picture quality and all worked perfectly.I repeated the whole process with my computer & 2x FHD 1080p Monitors. It works perfectly as expected I did notice a tiny loss in picture quality. It's a very slight loss, but a small reduction nonetheless. Playing videos with different resolutions were automatically detected including changing the computer's output resolutions.I notice the unit did get a little hot after a few of hours but not hot enough to be concerned with. Considering the price (£10) I think it is excellent value and it does what it say it does very well. I cannot confirm any performance with 4K operation. For anyone wanting to display the same content on 2x monitors/TVs from a single source, I would definitely recommend this device. I would say using higher video content and longer cable length would result in noticeable drop in picture quality & too much for this little device to cope with. I will certainly update this if I get my hands on a very long HDMI cable.I hope this helps and is useful.

Good product once tight connection with HDMI lead is established. Unfortunately it isn't fully compatible with hdmi-cec, but I don't know I'd any splitters are.

It works! I wanted to have the Sky TV also showing on my computer monitor in the corner of the room and this did just the trick. I don't see any quality loss either (which I presume is because hdmi signals are digital). I watched some 4K content too (Sky Q) and it also seems to be the same as without the adapter so I'm really pleased. Would recommend to anyone who needs one.

Works as described but occasionally drops out for a second or two. Annoying while playing games!

Does not support 4k ultra hd. As soon as i plugged it in from a skyq box my tv said unable to view uhd as device not compatible. Will split tvs ok . But you lose uhd. So not what it claims to be. Wasted my cash

It does work, which is what keeps this review from being one star, but the power USB-Micro B input is extremely flimsy. Trying to insert the cable can (and did, for me, on the first try) bend the port up in to the body of the device, and even after reinforcing it myself with some hot glue it still broke off entirely after a handful of insertions - which I needed to do because sometimes the unit wouldn't let my TV recognise a HDMI signal without being power cycled. The unit does WORK without external power IF it can get anough power from the HDMI inputs themselves, but introduces some lag time to the video - not a big deal for movies, but I am using it to run one side to my TV and another to a capture card for gaming, so input latency messes with things a fair bit. If it can't get enough power from the HDMI inputs after the USB-Micro B has snapped off (Like if you have it connected to a splitter) then it won't work properly.

I used this in conjunction with the HDMI to VGA cable to split my TIVO HDMI output to both my TV and my spare VGA input on my old monitor.Works great and great quality too without any quality degradation.May buy one for my bedroom to split my TV HDMI input from my DVD to my TV to another TV in another room.

Does exactly what's required no problems, easy installation, quick delivery. Happy with purchase

Prodotto acquistato per essere messo in cascata ad un sintoampli che gestisce anche l'uscita HDMI.una delle uscite di questo splitter è andata a una televisione l'altra è andata ad un convertitore di segnale su cavo LAN :nessun problema. l'oggetto è molto piccolo, molto solido, con un case in alluminio davvero robusto. Unica cosa da fare attenzione, all'interno della scatola microscopica NON C'È l'alimentatore: basta un alimentatore da cellulare connettore micro USB con 1 ampere, o 1000 mA, Dipende come lo leggete, nel mio caso più che sufficiente per fare un tratto HDMI da 2 m per la TV e andare nel convertitore con un cavo da 1 mSoddisfatto

Se calienta demasiado, espero que no sea un problema a la larga, pero es el único spliter que me lleva sin problema la señal a varias tv con más de 15 metros de distancia

visiblement ce boitier ne fonctionne pas. J'ai questionné la Sté sur les Pb rencontrés, elle est dans l'incapacité de répondre malgré l'obligation qui lui est faite de répondre sous 48 h

Funziona bene x il mio lavoro

Excelente.No le pongo ninguna pega
