What kind of HDMI cable do I need if I want to connect my Raspberry PI to a full HD ( 1920 x 1080 ) TV (which has HDMI input)?
According to the Wikipedia, there are 5 types of HDMI connectors: A, B, C, D, E, and several types of cables: Standard, High Speed, Automotive. Which one should be used?
You want a HDMI Type A to HDMI Type A; they are the most common cable used to connect DVD players to TVs.
Any type of cable should do. If you want to watch high-quality video and listen to high-quality audio, it's worth spending a little more on the cable. For example, gold connectors will the contact between the cable and the connectors on the RPi or the TV. If you are just using the console, a cheaper cable with probably be fine.
Automotive cables will be extensively tested for extreme conditions, such as low/high temperatures; they are unnecessary for every day use.
I would only advise on gold plating if the other connector is also gold plated. Mixing metal connectors can cause corrosion issues, depending on the metals (gold will not be the problem).
On my Pi-B the SD slot is not gold plated, but the Ethernet plug is. The RCA video is not, and it looks like, but I cannot confirm, the HDMI is gold plated.
Depending on your long term goals, and the environmental conditions where the Pi will be living most of the time, you gold may be worthy. I myself spend the 10-20% more on the gold as the quality of the cable is often much higher as well.
I bought this cheap $7 gold-plated HDMI to DVI cable adapter from amazon.com and it works perfectly with my Raspberry Pi and Dell LCD.
