In case of Category 1 certified cable:
For high qualty cable, u should be able to transmit data without any error on 1080p device.
For a low quality cable, u must be very lucky for it to works on 1080p (yes, it can work)
Why? because no test to certify that the cable able to operate at least 1080p. Those low quality cable might just barely pass the test. You can buy certified category 2 cable to be sure. But of coz, prepare to pay more

hope this help

Funny, I would have thought otherwise. 28AWG is the lightest cable as such it would put the least stress on the connections. 22AWG is the heavier cable and if not properly secured will cause loosening at the connector in the outer and inner areas. That is why better companies offer bonded ends when they use the lower AWG.

there goes all your less bright, less sharp, blurrer , less vivid image due to upgrading to more expensive brand of HDMI cable nonsense.. 

bottle neck at Optical transport transfer speed (not at peak interface bandwidth) (and interface i.e. SATA, HDMI is just video connection without error correction)

what is all the fuss? u want to buy cheap HDMI buy la. I NEVER said it wont work. but there is no gurantee it will work. If it work, just enjoy ur saving

Gold is definitely better than silver isn't it?

no, they will sell $2000 wireless receiver that have super duper secret algorithm that enhance the wireless transfer to make you image super sharp and audio super crips.

If it's certified with the same specs, very likely it will perform the same.

Why Monster and other branded cables are so expensive?

These manufacturers need to build the cable accordingly to meet the certifications standards and required $$$.
