Hdmi cables are only reliable , that is, can only be guaranteed to work with any content,and any piece of equipment, up to 8 meters.

8 meters is the limit because no cable longer than that has ever passed the category 2 or high speed hdmi test.

After that the signal drops off due to attenuation, so whether it works or not depends on the strength of the signal from your source.

20 meters is way too long for a hdmi cable, over that distance you are far better off with hdmi to 2xcat5 converters.
