The HDMI questions has been on in this thread for more than a year.
I have recently listened to a podcast that clarifies many things about HDMI and here is what they have to say:
http://twit.tv/htg11Q: How many types of HDMI cables are there?
A: Four types, according to HDMI licensing: HDMI Standard, HDMI High Speed, HDMI Standard with Ethernet, HDMI High Speed with Ethernet.
HDMI Standard is able to carry a maximum bandwidth of ~4.2Gbps which is capable of delivering high definition content of up to 720p/1080i.
HDMI High Speed is able to carry a maximum bandwidth of ~10.2Gbps which has enough bandwidth to deliver a full 1080p signal and even up to 4K.
Q: Are expensive HDMI cables always better than regular HDMI cables? Am I going to get better colors and image quality?
A: The HDMI licensing board has defined a minimum specification for HDMI cables and, as long as it can comply with the specifications (delivering content up to certain bandwidth, etc), in other words, if a standard HDMI cable meet the specs, then there wouldn't be such thing as it underperform than other more expensive HDMI cables (better image quality, etc.) If the manafacturer says that gold plated HDMI cables have better image quality, then the manufacturer would have to justify its claims that upsells their product.
Q: I don't get any picture when connecting my PS3 to my LCD TV. Could it be because my HDMI cable is faulty?
A: It may be because it is faulty, and sometimes, not really the case. Some of the issues has been traced to HDCP (High Definition Copy Protection) incompatibility between devices. Sometimes it could be solved by firmware upgrade (if it can be supported by the TV). One way to test is to try using another HDCP--compliant device such as a camcorder or laptop, plug it into your TV with the HDMI cable and test. If it works, then it may not be cable problem, but actually HDCP issue.
Hope that helps.
