Provided both the transmitter device (Sky or Virgin box, DVD player etc.) and the TV receiving the input have a SCART socket or can take the RCA/Phono cables (red, yellow, white) then the signal from the transmitter will be sent to the other TV. To watch the programme, the receiving TV (whether it be a Smart TV or not) will have to have its Source selected as appropriate. This will generally be A/V or EXT. **Q: Each time we switch the downstairs tv off and switch the tv on upstairs, it also switches the tv back on downstairs. Any ideas how to fix this?** A: Unfortunately the same thing happens to me. I now unplug the downstairs tv before going to bed. **Q: Silly question, but does it need to be connected to wifi? Its for my dad who doesnt have the broadband. Thanks very much** A: Hi, no just plug the transmitter into the sky box or whatever you are sending, and the receiver into the tv you want to watch on. Then just set the channel to the same number on each unit. Sends our sky from the lounge to the bedroom through 2 solid bricks walls very well. **Q: Can you use with a dtr t-2100 youview box** A: I would think so, I am using mine on my Iptv box to transmit to my tv in the living room from my bedroom ## Customer Reviews ### ⭐⭐⭐⭐⭐ Excellent value for money *by L***. on 24 January 2021* Very straight forward to install and so far extremely happy with it. Our old A/V sender only had 4 channels and was affected by the microwave, the Wi-Fi - even by other household's appliances! As we use use it to watch tv in our kitchen this was extremely frustrating! This one has none of those problems with so many different 'channel's and it is great to be able to continue watching a programme while heating the baked beans!It has a good range too. The sky box is up in the bedroom on the third floor and the picture quality and sound in the kitchen is excellent. One word of warning; we recently had a power cut and afterwards had to turn it back on and reset unlike many appliances that just switch back on as they were. Not a big issue at all tho'. ### ⭐ Not HD and only for tv's 40" or less. *by L***X on 25 June 2022* Firstly, considering this item is currently being sold for almost £55, I was surprised by just how cheap looking and light it actually is. It's obviously plastic, but feels thin and doesn't give you the impression that it would actually last very long, especially if you were unlucky enough to drop it. From the weight of it, it seems that there isn't a great deal inside the casing and the connections seem loose. Despite these issues, I connected everything up as the instructions tell you, switched both units on...and got absolutely nothing. I tried various frequencies, hoping that something would appear, but nothing.What isn't made clear when you decide to purchase this item are two very important points that you really need to be aware off. According to the instructions, it should only be used with tv's that have a screen size of 40 inches or less. Mine is 75 inches. More importantly however is that you don't get HD picture quality (assuming you're lucky enough to get it to work). The instructions tell you that the picture quality will be 480x620. If I had been aware of these two points beforehand, there is absolutely no way I would have even bothered to place an order. ### ⭐⭐⭐⭐ Good over short distances, but it has its quirks. *by A***T on 22 December 2020* Fairly easy to connect up, but the lag between sound and vision (especially when someone is speaking - lip sync) meant we had to buy better quality HDMI cables and though improved it still happens. Also, in snooker for example, rolling balls don't run smoothly. Probably the most annoying of all is that our satellite remote control causes our second TV in a different room to turn on. The only solution seems to be to unplug it. Frustratingly I haven't been able to determine what causes this (sorted - see below). However, having taken these into consideration, the picture and sound quality is far better than our previous video transmitter. Given that the transmitter and receiver are less than 10 metres apart, separated by a wood and glass partition, I doubt this equipment is suitable for transmission through a brick wall. Asked by Amazon to comment on "sheerness" I haven't a clue what this means.EDIT: If you plug the little control "mouse" into the socket on the transmitter and cover it to block the signal the remote TV no longer switches on. ## Frequently Bought Together - Redlution 4K Wireless audio Transmitter BIN-850 Wireless HDMI Extender TV Audio Video Transmitter and Receiver, Digital Signal Full HD 1080P 3D AV Sender - OREI HDMI Splitter 1 in2 Out 4K - 1x2 HDMI Display Duplicate/Mirror - Powered Splitter Full HD 1080P, 4K @ 30Hz (One Input To Two Outputs) - USB Cable Included - 1 Source to 2 Identical Displays - OREI UltraHD 4K @ 60 Hz 1 X 4 HDMI Splitter 1 in 4 Out 4 Port 4: 8-Bit - HDMI 2.0, HDCP 2.0, 18 Gbps, EDID, Duplicate/Mirror 4K Screens - UHDS-104 --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.pl/products/420381826-4k-wireless-audio-transmitter-bin-850-wireless-hdmi-extender-tv](https://www.desertcart.pl/products/420381826-4k-wireless-audio-transmitter-bin-850-wireless-hdmi-extender-tv) --- *Product available on Desertcart Poland* *Store origin: PL* *Last updated: 2026-05-07*
