Not suprising. 1080p24 3D from a BD player requires less bandwidth than 1080p60 2D.
Sometimes I need to reduce to 1080i or even 720p to get an image.
This is indicative of insufficient bandwidth.
I tried some shorter cables to connect the same source. Not a problem.
Confirmation of insufficient bandwidth.
The long cable is getting worse and worse over time.
Maybe you are just getting more sensitive to the problem? Could be how the plug mates with the socket. Could be bad termination of wires getting worse from flexing or having too much stress on them.
I am really puzzled why HDMI cable can degrade over time?
They don't, at least in any kind of reasonable time frame. If there is a problem, it is typically with the termination of the wires at the plug, or the mating of the plug with the socket.
Does it mean all cheap cables are bad? I now have little faith on cheap cables.
No, monoprice cables are cheap and have a good reputation.
I don't want 24 or 22AWG cables...
What you want and what you need may be two different stories.
Is monoprice redmere cable my only choice?
It is one choice. An alternative would be an extender that uses Cat 5e/6 cable. Cat 5e/6 cable is relatively easy to run. The only caveat is that anything short of a HDBaseT solution is a crap shoot. There are also fiber optic cables.
Will it degrade over time?
Well, because it has active electronics, it is pretty much a given that it will fail someday. Any electronic device that is not hermetically sealed will degrade over time. But it should be a very long time.
But it only has 30ft which is longer than I need.
Not a problem. The electronics are matched to the length of the cable. That is the great advantage of Redmere over an add on equalizer.
