S850 Upgraded Type-C Wireless HDMI Transmitter and Receiver, 50M, Ultra 4K Decode Input 1080P@60Hz Output, Plug&Play 5G+2.4G and Audio for Phone/Tablet/Laptop/PC to Monitor/Projector/TV (Orange)

Awesome work perfectly as advertised

Traditional HDMI cables for connecting TVs and projectors are not only troublesome to route but also tend to create clutter. That’s why I purchased this wireless HDMI transmitter and receiver set. Its wireless transmission, plug-and-play design, and dual-mode functionality perfectly meet my needs. In receiver mode, simply connecting the RX device enables screen mirroring without requiring an additional transmitter, making the setup extremely simple. When using transmitter/receiver mode, just plug in both the TX and RX devices—they automatically pair without any complicated configuration, truly delivering a plug-and-play experience. During use, the picture quality is clear and smooth, with no noticeable delay when streaming videos or giving PPT presentations. It also provides a relatively long transmission range, maintaining a stable connection even when used between the living room and bedroom. Charging via Type-C is convenient, and the overall setup process is straightforward and user-friendly. It supports both mirror and extended display modes, making it suitable for office meetings, online teaching, home entertainment, and gaming. This wireless HDMI device balances convenience, stability, and high-definition image quality. It keeps desktops tidy and connections flexible, making it a practical tool for enhancing both work and entertainment experiences.

One piece stayed near the phone stand while the other slipped behind the projector input. A small Type-C plug extends directly from the transmitter, so the phone connects without extra cables, and the larger screen begins showing the same image after a brief moment. A charging line runs into the side of the transmitter at the same time, letting the phone battery climb slowly while the video continues playing. The receiver remains hidden behind the display once inserted, leaving only a narrow silver edge visible if looking from the side. Metal shell feels smooth in the hand when picking it up again to switch devices, though the surface shows faint fingerprints after moving it around the desk a few times. Later the transmitter sits beside the phone stand while the receiver stays in the display port, the larger screen quietly reflecting whatever moves across the phone screen.

While organizing my work desk at home recently, the most annoying thing was all the cables. Connecting my laptop to the monitor and projector meant unplugging and replugging everything every time I moved it. After switching to this wireless HDMI transmitter, my desk is much tidier. Once the transmitter and receiver are connected, there's basically no need for special settings; the screen displays the image quickly, and the operation is very intuitive. I usually use it to project my laptop screen onto the living room tv to watch videos or share photos. The playback is very smooth, and switching between videos or dragging the progress bar is quick with no noticeable lag. The audio is also transmitted synchronously, making for a great experience when watching movies or tv shows. After using it for a while, I find its greatest convenience to be its flexibility and compact size, taking up minimal space in my bag.

Palm lifts the small metal transmitter from the desk and the matte shell sits cool against the fingers. USB-C plug slides into the laptop port while the receiver pushes into the HDMI slot on the monitor, then the tiny indicator light turns on and the desktop screen appears across the display without opening any apps. Thumb taps the narrow power button once and the video from a tablet shows up on the TV across the room, the picture staying stable while a short clip plays. Back edge of the unit feels slightly rounded when sliding it back onto the desk, not sharp but noticeable when turning it over in the hand. Short strap loop hangs from the corner and makes it easier to pick up again when switching devices. Receiver stays connected behind the monitor while the transmitter moves between the laptop and a phone, the small metal body lying flat near the keyboard with the cable tucked loosely along the side of the desk.

I have been very pleased with the performance of the HDMI Transmitter and Receiver. The setup process is truly simple and user-friendly. I especially appreciate the new Receiver Mode, which allows me to mirror my screen just by connecting the receiver, without always needing the transmitter. It makes everyday use much more convenient. The plug-and-play design works exactly as described. There is no need for Wi-Fi, apps, or complicated configuration. The connection is fast and stable, and the video quality at 1080P@60Hz looks clear and smooth. I have used it for meetings, watching movies, and even light gaming, and the experience has been reliable. The 50-meter wireless range is also impressive, providing flexibility without messy cables. I also like the Type-C charging feature, which lets me charge my device while using it.

I originally picked this up because I was tired of dealing with HDMI cables every time I needed to share my screen in meetings. The first time I used it, I plugged the transmitter into my laptop and connected the receiver to the TV, and the screen appeared almost instantly. There was no setup process or extra steps, which made the whole experience feel very straightforward. During presentations, the connection stayed steady even while moving around the room. Slides, videos, and documents displayed clearly, and motion looked smooth without noticeable delay. The audio also matched perfectly with the video, so switching between speaking and playing media felt natural without interruptions. I’ve since started using it at home as well when I want to mirror my tablet to the TV. Not having cables stretched across the room makes everything feel more organized, and packing the device in my bag is easy when I need it somewhere else. After regular use, it’s become one of those small upgrades that quietly makes everyday tasks simpler.

Works great. Something to keep in mind. Doesn't with with Google pixel devices.

llano per migliorare l’organizzazione delle riunioni nella nostra sala conferenze, e devo dire che è stata una delle migliori decisioni tecnologiche degli ultimi anni. Lavoriamo spesso con presentazioni in 4K, grafici dettagliati e video dimostrativi, quindi avevamo bisogno di un sistema stabile, fluido e semplice da utilizzare anche per chi non è particolarmente esperto di tecnologia. Il collegamento è davvero plug & play: basta inserire il trasmettitore nella porta USB-C del laptop e il ricevitore nel monitor o nel proiettore tramite HDMI, e in pochi secondi l’immagine viene trasmessa senza configurazioni complicate o installazione di driver. La compatibilità è stata perfetta sia con PC Windows che con MacBook aziendali. L’ingresso supporta l’Ultra 4K e l’uscita a 1080P@60Hz garantisce un’immagine estremamente fluida, senza scatti o ritardi percepibili durante lo scorrimento delle slide o la riproduzione di video. La doppia banda 5G + 2.4G offre una connessione stabile anche in ambienti con molte reti Wi-Fi attive. Nella nostra sede ci sono decine di dispositivi collegati contemporaneamente, ma la trasmissione rimane stabile e priva di interferenze. Anche la latenza è minima, elemento fondamentale quando si devono mostrare video o demo software in tempo reale.

Si te encuentras que deseas conectar 2 dispositivos por cable HDMI, pero que o bien, no es cómodo, o no tienes el cable adecuado, o hay demasiada distancia entre ambos puntos, esta puede ser la solución más sencilla y cómoda que puedas encontrar. La teoría es sencilla: un emisor y un receptor de audio y video. * El emisor (marcado como TX) lo conectas a tu Smartphone, tablet, u ordenador. Al emplear un conector USB-C macho, ya recibirá paralelamente la energía necesario desde dicho puerto para poder funcionar. Además, tiene una entrada USB-C hembra, la cual, hace de puente y te permite por ejemplo, cargar tu Smartphone mientras estás empleando el emisor de señal. * El receptor (marcado como RX) lo conectas a tu TV (no hace falta que sea Smart), Proyector, o monitor. Se conecta mediante un cable HDMI que ya tengas, un extremo va en el receptor, y el otro extremo por ejemplo, a la TV. Como la conexión HDMI no dispone de voltaje de alimentación, necesitarás emplear el cable USB adjunto para conectarlo al receptor por un extremo, y por el otro por ejemplo, a un puerto USB-A de la TV, el cual ya dotará de los 5V que necesita el receptor para funcionar. A continuación , necesitarás emparejar por Bluetooth emisor y receptor. Se te pide un código (1538) que deberás introducir en la parte del emisor (Smartphone, ordenador, tablet..). A partir de ese momento, todo lo que emita cualquiera de estos dispositivos, se verá por el canal de HDMI del receptor. De este modo, puedes por ejemplo, emitir Netflix desde tu Smartphone a una TV que esté muy alejada, o que incluso no sea una SmartTV. También puedes hacer presentaciones en Proyector desde tu ordenador portátil, para que se vea en grande en una reunión de trabajo o evento con pantalla grande. Los puntos fuertes de este dispositivo son muchos. Desde poder emitir hasta una distancia de 50m (o 10m si hay muchas paredes entre ambos), replicar la pantalla o emplearla como modo extendido a distancia. Todo ello, siendo compatible con Android, iOS, Windows, y Mac OS. Tras probarlo, el emparejamiento entre mi Smartphone Android y una TV de 32" (que no es Smart) ha sido rápido y facilísimo. Tras su uso, y si va a repetirse en el futuro, únicamente deberás desacoplar el emisor de tu Smartphone por ejemplo, pero puedes dejar el receptor en la TV. Cuando lo vayas a emplear de nuevo, solamente habrás de presionar el botón del receptor y listo. La calidad de la transmisión y recepción ha sido perfecta, sin cortes, ni desincronizaciones, ni lags, perfecto. Súper recomendable, de un fabricante que se dedica a esto, y a un precio más que razonable. Besitos! (✿◠‿◠)

Running incredibly long cables across a living room floor is a tripping hazard. Plugging the transmitting dongle into my laptop and the receiver into the television screen initiated a connection almost instantly. The video feed mirrors my laptop display perfectly, allowing me to stream films directly to the big screen. The picture quality remains sharp and clear, handling fast-moving action scenes without any noticeable lag or stuttering. Audio syncs up flawlessly with the video, avoiding that annoying delay where lip movements do not match the spoken words. Both units require external USB power to function, adding extra cable clutter behind the television and tying up a port on the laptop. The transmitter gets noticeably warm after an hour of streaming, which is slightly concerning for long-term durability. It struggles slightly when a solid brick wall is placed between the two units, causing the signal to drop occasionally. In an open-plan room, it performs its primary function reliably, keeping the floor entirely free of trailing wires.

Voilà un accessoire très utile. Ce kit permet de relier sans fil un appareil équipé d'une sortie video sur port USB-C (testé avec un HP Elitebook et un Samsung S25+) et un écran avec entrée HDMI. Tous les accessoires sont inclus, en dehors de l'alimentation pour le récepteur. Le système se présente comme 2 demi-carrés qui s'emboitent pour le transport. Les 2 éléments ont un bouton qui permet de lancer l'appairage, ou de couper la transmission. Le bloc émetteur permet de connecter l'appareil en USB-C, et ne nécessite pas d'alimentation supplémentaire. Une rallonge de 20cm est fournie au cas où l'appareil bloquerait d'autres ports sur votre appareil. Le bloc récepteur présente un port HDMI femelle (un câble mâle/mâle est inclus) et un port d'alimentation USB-C (le câble USB-C vers USB-A est fourni également). Point intéressant : le récepteur est compatible avec Miracast et la fonction d'écran connecté des Macs et PC Windows, même sans utiliser l'émetteur. Lorsque l'écran est allumé et le récepteur branché, il affiche une page (malheureusement en allemand) donnant les informations sur comment se connecter. Le fonctionnement est globalement bon (dans la limite du 1080p 60Hz), même si il est parfois un peu difficile de se connecter en écran distant (mais comme tous les autres appareils, y compris des solutions haut de gamme). Le Samsung affiche bien Dex sur l'écran, et il n'y a pas d'interruptions du flux, la connexion est très stable. Les 2 appareils chauffent, mais sans perturber le fonctionnement. J'aurais préféré une coque en métal. Bref, à avoir dans son sac en déplacement, c'est top.
