Hello all,

I'm facing a strange issue with my new TV Samsung 7 model. Here is how the connection looks like:

laptop HDMI port > HDMI extender TX > two RJ45 CAT6 cables > HDMI extender RX > TV HDMI

The problem is that the TV is showing me NO SIGNAL. I used the same cables/extender with my old Toshiba TV and all was working OK. Also now, when I connect the Samsung TV, the laptop recognize a new screen, but there is still NO SIGNAL on the TV. When I connect laptop directly to TV with HDMI cable, it works.

any ideas what could be wrong?

Thank you all in advance.
