Used for streaming from an old Lenovo laptop, and a brand new surface book, and works perfectly on each. Used with a Samsung TV, and a Denon receiver hooked up to a Panasonic projector for high def audio and video. We have 1080p and not 4k, but works awesome.
I have had this for a few weeks now and it works perfect. There are no handshake issues and I connect it and disconnect from my monitor daily. There are other ones on Amazon that Iâ??ve owned however I would have to connect and reconnect, restart etc before it would work.
