This kit can have up to 3 receivers connected the transmitter . Once again thank you for choosing IOGEAR .
A:AnswerThe wireless HDMI includes an IR repeater that allows you to access all the functions of the cable box remotely. Depending on your cable company, you can order the same remote so that you can program it to turn the remote TV on/off and access the cable box.
A:AnswerIOGEAR says: Depending ion the distance the GWHDBBKIT should work for this situation. I would recommend a kit like the GW3DHDKIT since this kit is designed to go through walls and Barrier. For optimal performance we recommend a line of site for the GWHDBBKIT . This kit has a range of 150 feet with a line of site. Thank you for choosing IOGEAR.
A:AnswerIt simply replaces a single HDMI cable. So yes, if your DVD player has an HDMI output and your TV has an HDMI input it will work great.
The kit comes with everything you need including two HDMI cables to plug into the transmitter and receiver. I cannot answer about multiple TV's.
A:AnswerIt does indeed work with the Switch. There is the slightest input lag from controller to playback but it still better than my NES/SNES classic hardwired to the TV. Still completely playable for about 90% of my games.
A:AnswerIOGEAR Says: The Transmitter when connected to the source will transmit audio and Video though the HDMI connection. Thank you for choosing IOGEAR
