Ndi ko matandaan kung saan ko nabasa pero a 5kphp HDMI cable does not make a difference from a 200 php HDMI cable from CDRking and that a HDMI Deep Color cable does not mean anything.
depends on what version of cable you have. there are some cables still supporting hdmi 1.2 specs, which means it does not support deep color. only the latest specs which is hdmi 1.3 a to c supports deep color. that being said. you are right. if both cables (expensive and cdrking) are hdmi 1.3 spec'ed, in theory it should perform the same, the only difference is maybe in build quality.
as for deep color meaning anything, i think sir jerix has answered the question already:
If you want to benefit from this, it requires that the source material and the equipment to output this should also be deep color capable.
so even if you have it, but the bluray and your bluray player does not support it, it may be nothing, but as any technology, it takes time before it goes mainstream.
