Handles everything!
I connect everything from a current gen xbox all the way to a ps2 via component through my av amp and it handles all of it. 4k, hdr, 1080p, 576p and 480p. Its great. I just left it in its default setting and it works a charm.

Works perfect with full Dolby 5.1 compatability
Worked a treat on my ancient Denon 3802 receiver. The only available input left for my DVD player (optical Toslink out) was an assignable coax/toslink input which is set to coax and due to handset issues, no longer changeable. This works perfectly changing optical to coax in. Full Dolby 5.1 etc. Well pleased.

Simple great value device
Very early days and very little testing but we are using this to route various devices to an old 1080p projector and a 4K TV and so far it is doing it very well with the switches set to mode 1. Being USB-C is an added bonus as it meant it did not need an additional plug in our rack cabinet. Only tiny criticism I would have is that it does not pass the power on signal when you attach to a Chromecast for example so I'm getting there is no HDMI control signal being passed through. Remote control is very intuitive and simple to use

Ok
It works ok not brilliant the ig drawback is the remote have to be pointing straight at the equipment to switch channels and fairly close worth the money though

Great audio solution.
It’s a simple box that routes my optical cable input to a digital coaxial output. As my amplifier has a broken optical in but a coaxial in, this was a great solution. Quality product at a good price.

Brilliant HDMI hub
I have several devices that used hdmi that I wanted to connect to my monitor. This takes up minimal space and its very easy to set up and use. Allows for 4 input devices and 2 outputs which means I can connect my monitor and capture card and switch between them with a simple button push on the remote

Great Matrix Box.
This HDMI Matrix Box is perfect. I have 4 inputs Sky TV, Apple TV, Laptop and a Console, their signals are sent to 2 outputs 1 to a TV and the other to a Home Cinema Projector. I also extract the audio to my soundbar and stereo. It let 2 shows, films, games etc to be shown at the same time, 1 on each screen. Each HDMI out has it own audio extraction connections. I would recommend this device to anyone that has multiple devices they would like connected to either 1 or 2 screens.

Works perfectly at a good price
Purchased to allow for HDMI outputs between my TV and Monitor on a desk. I was originally wary it may struggle to work as the HDMI cable to the monitor is over 10m. To my surprise, once I had worked out the EDID mode required, this works perfectly with an Xbox Series X and PC. Would recommend and much cheaper than many alternatives

高級なセレクターとかありますが、アナログやUSBと違い、劣化とか光にあるのでしょうか????? 光の速度でデジタルデータを伝えるのに電磁波が余計ないたずらするような感覚わかならないけどあるんでしょうねー ただ一般人としてはこのセレクターで十分だと思います!普通に使えるし満足です!ちょうど二つ必要だったので二つ買いました!どちらもしっかりつかえます!

La matrice HDMI 4x2 offre un’ottima flessibilità per chi ha più dispositivi come console, lettori e decoder, permettendo di inviare i segnali a due schermi in risoluzione 4K senza perdita di qualità. Il telecomando incluso semplifica il cambio sorgente, anche se serve un po’ di tempo per memorizzare le combinazioni di ingresso e uscita.

以前も同様の商品を使用していて、壊れたため買い換えました 期待通りの動作をしてくれています 本体は薄く、LEDのステータスもシンプルで分かりやすいです 私の場合リモコンは使用しておらず、本体のスイッチで切り替えていますが、最初からすんなり違和感なく使用できています

Pas besoin de plus cher ! Utilisé pour relier divers matériel en ethernet avec minimum de pertes grâce à ce switch simple efficace et de bonne qualité (structure métallique), possibilité de le fixer de différentes manières ou de simplement le poser. Dimensions idéales. Ne pas oublier qu’il faut aussi prévoir l’alimentation électrique.
