What are the different versions of HDMI?
HDMI was released in 2002 and since then it has undergone several upgrades. HD technology has undergone some popular upgrades such as Dolby True HD, DTS HD Master audio support, super audio CD support and DVD audio support.
Will my existing HDMI cables work for newer versions of the technology?
HDMI as a technology may get upgraded; however the cables do not need to be. The HDMI cable is the most advanced data transmission cable in the world today and has the capacity to handle future technology upgrades.
Does the HDMI cable need to be thicker the longer it is?
Long HDMI cables can run over a distance of 50 to 100 feet. The wire gauge is thicker for these purposes and hence the cable will also have to be thicker. Thinner cables over long distances do not give high quality audiovisual outputs.
