Review on 📶 Ultimate Wireless HDMI Transmitter and Receiver Kits: Stream 4K from Mac, Laptop, PC, Smartphone to HDTV and Projector Wirelessly with the Powerful Wireless HDMI Dongle by Vedprakash Trilltight

I use this to stream from my cable box (which is connected to my main TV) to my second TV. The picture quality is excellent, the transmitter and receiver are coupled out of the box. This kit is advertised as plug and play, however this is only true if the source's HDMI output (for the transmitter) and the TV/monitor's HDMI input (for the receiver) can provide enough power to operate the transmitter and receiver to supply with electricity. For me, my HDMI output was sufficient, but the HDMI input on the TV that receives the signal wasn't enough to power the receiver. Each dongle (transmitter and receiver) has a USB-C input so you can connect an additional power supply. The manufacturer includes two USB cables specifically for this purpose, but no power adapters (a regular phone charger with a plug without a cable). I think if you advertise them as plug and play and sell them for about the same price as comparable solutions, everything you need should be in the box to be truly plug and play. Determine if your HDMI input and output ports provide enough current to power your devices. Otherwise, moving your laptop or expanding your cable box like I did is a good solution.
