So I'm looking to ditch the mini-hdmi adapter I use on my camera and go with a dedicated hdmi to hdmi-mini cable. Has anyone had any experience with these cables that they've used to output to a monitor? I'm looking for a 25ft cable but I was wondering if the length of the cable makes any difference in that it might lose signal going from the camera to the monitor. Also, is there a certain type of cable I should look for? Some of the ones I'm seeing online say they support ethernet and 3D. Things I know I don't need but I'm wondering if the additions of those might mess up the signal from the camera.
