Meanwhile, if your v1.3 cable is shorter than 5m, it'll also pass 3D signal without much problem.

That's textbook rule. Real life HDMI has 30awg, 28awg, 26awg, 24awg. It's better to limit to 5m than 10m which your picture quality can suffer due to other factors such as connector, gauge and contact point soldering.

hi experts,

I own a HD plasma TV (1024x768), and plan to get a bluray player after this, i suppose all bluray player is supporting full HD (1920x1080) rite, so the bluray movie quality will get some sort of 'down-convert' to HD scale and send to my TV rite?

Then the question comes, for this application do I really need a HDMI v1.4 cable? Or v1.3 will do the job well?? I not really sure whether my plasma TV support ARC feature (It's a Samsung Plasma PS51E451 model).

v1.3 cable can get below rm50, but I think v1.4 cable close to rm100?

If I am using v1.4 cable, what sort of advantages do I get from this? Assuming in future I will use the same HDMI cable to plug from my laptop to TV.
