After opening up the package I noticed this Black Platinum HDMI cable has one end marked "TV" with no mention of this on any instructions or packaging. I attempted contact Monster without any success. I have several questions regarding its capabilities and would appreciate any response from our forum members:
1. Why is one end of the cable marked TV? This one suggest data flow in one direction only which I never heard of before.
2. Will the cable function normally if the end marked "TV" was plugged into the AVR?
3. Is this Black Platinum HDMI cable ARC capable if data is only transferred in one direction? The packaging clearly states that this cable is ARC capable.
4. Is this cable eARC capable?
5. Will this cable support HDMI 2.0b which is necessary for HDR & 4k/60p?
The cable is an active cable meaning that there are chipsets in the sink end (tv side) that aid in error correction, timing, etc for cable distances longer than the certifiable 25'. The active portion (tv side) draws a little power from the HDMI input to operate the chipsets. If you install the cable backwards, you won't damage anything but you may not get any video or video that is messed up.
If you bought a Monster cable then you paid too much. There are other cables that offer the same performance at less money. Cost does not guarantee anything.
Premium High Speed HDMI cables are certified by HDMI.org to meet the HDMI 2.0b hardware specifications, which includes 4k HDR at 18Gbps. However, as I mentioned, certification is only good up to 25', so far. The cable should come with a QR label for authenticity. However, there are no 100% guarantees that the cable will work in your setup, there are just too many variables.
The cable is just a data pipe. It just transfers the signal (whatever it may be) from Point A to Point B hopefully without any errors. eARC is a function of the HDMI chipsets in your source (blu-ray player for example) and your sink (tv). Both devices need to have the same HDMI hardware versions (chipsets)
to support eARC. Otherwise, the communications will only be able to use the in-common HDMI hardware protocols and options. If there is no mention of ARC capability in the cable documentation, then it probably isn't ARC capable which means in won't be eARC capable.
If you cable run in only 12', then I would recommend a passive Premium High Speed HDMI cable (with the QR label) from someone like Monoprice, BJC (the cables I use), or MediaBridge.
