NAMCIM Wireless HDMI Transmitter and Receiver, Plug & Play, No Delay, Ultra HD Wireless HDMI Converter Dongle Adapter, Streaming Video/Audio from Laptop, PC, Smartphone to HDTV Projector

Need to send audio video to a monitor or TV from your laptop this thing shines. It could not have been. easier to set up quite literally plug and play. I screen mirror my mac to my TV, Projector, and monitors in the office with these devices they work great.

This thing is so cool. I always hated to run a long HDMI cable across the room to connect my laptop to the TV or projector. With this I can just plug the little wireless transmitter into the laptop and sit in the chair and wirelessly transmit to the receiver plugged into the TV or projector. How cool is that? The receiver requires power from a USB port. You can plug into a USB port on the TV or projector, or a power block you have to provide. There are instructions on how to pair the transmitter up with the receiver, but they come pre-paired I guess, because mine was just plug and play. You can also use screencast from a cellphone or a tablet wirelessly to the same receiver if your TV doesnt have that capability built-in. Im loving this so far .. thumbs up!

Works like a charm

No cables! Easy plug and play. Great if you want a portable device or if you want to set up another screen and not have to run wires. Works just as well as having a cable plugged in. From what Ive tried, no issue with audio or video synchronization.

This is a cool idea but when we plug the transmitter into the laptop to broadcast to a 43”’tv in our conference room, the transmitter loses the signal unless we attach a usb-c power cable to a charging cube and give the transmitter power. It when it works it works great. I used Velcro strips to attach the receiver to the back of the TV to hide it - only the little antennae hang down.

I returned this.

Range is not as good as advertised. Within 5-10 ft. it works great. 10-20 ft. it starts to lag. Beyond 20 ft. it wont let me connect.

Takes a while to figure out how to configure this thing. Once we finally got it working it seems to work fine. There is a little lag but that may be the internet dont know. I have used it with ipad hp laptop roku tv and apple tv with out any issues.

Good

It keep disconnected and return to the initial blue screen. Unreliable connection irritating and annoying. Dont recommend
