ScreenCast 4K HDMI Wireless Adapter Receiver | Wireless Display Streaming from Mobile, Tablet, or Laptop via AirPlay, Miracast, Chromecast, for Windows & macOS (JVAW76)

This product description is a lie. Its description is Screencast 4K, the box says "Supports 4K Ultra HD ar 30 Hz", and the website states "Stunning 4K Picture Quality, Enjoy a crystal clear resolution up to 4K and lifelike colors optimized for your TV.", but its all a lie. Having purchased this for one of our meeting rooms, I confirmed that when plugged into the tv, it said 4K 30p. When connecting to the dongle, Windows 11 would only allow a resolution up to 1080p. Having updated the device, and finding nothing to resolve it, i contacted the manufacturer's support. Their response:- "Due to the limitation of Miracast 1.0 that JVAW76 complies with, the output resolution of source device will be limited to 1080p, 720p and 480p. The JVAW76 will upscale the source resolution up to 4K with 4K display." This device is using a standard that was first ratified in 2012!. In July 2017, 2.1 was ratified, which does support 4K, however J5Create think its reasonable to claim a product can stream 4K, when its only capable of streaming at 1080p, and upscaling to 4k. Massive con in my opinion, and I will steer clear of any of their products in future.

Disappointing, had great hope for this , after trying to follow some differcult instructions and going back and forth with no luck, 1 hr of trying to set up , I gave up! And was quite expensive,

Works great

Produkten fungerar inte tillfredsställande. Den tappar ofta kontakten med datorn. Efter att ha mailat tillverkar blev jag rådd att köpa en annan produkt då detta tydligen är ett kännt problem. Jag ville då att dom ska ta tillbaka produkten men jag måste vända mig till tillverkaren.

Très bien

It was extremely easy to set works great no problem so far streaming no buffering problem

Great product for its price
