Doctorwizz and Danbfree,
My fault. I edited my comments to over certain lengths of HDMI cables.
According to MyCableMart rep, HDMI.org has admitted to retailers that the official statement that HDMI.org put out that "any HDMI cable certified as high speed to 1.4b standards would also meet all HDMI 2.0 standards and could be marketed as 2.0 cables" was wrong. This may have been the plan all along to get companies to buy into the new HDMI certification program that HDMI.org announced on October 5th, 2015, it may be that HDMI.org truly thought these cables would handle the 60 Hz requirement over all lengths. Regardless, my home theater company used a passive cable under 15ft and it handled the 60 Hz 4K signal without any problem. Same length with a Redmere active cable, no dice, regardless if from Monoprice or MyCableMart. The MyCableMart cable is using the Redmere PRA1700 chip. However, Monoprice actually told me that they were not allowed to confirm if their cable I used, #10767
, was the same chip or not. They acted like it was a government secret. I did inquire after October 5th, so they may also be scrambling to figure out their plan of action since these cables will not negotiate 4K @ 60 Hz as advertised.
The source is an internally generated video interface from each AVR/Pre-pro (Pio VSX-90 Elite and Marantz AV8802A). When you select these on the AV equipment, the signal is from a board inside the AV equipment and output on the HDMI out of each to the TV via the cable. The Marantz tech support said that their machine will check on the other end of the cable to see what the max display capability is and match. In this case, 4K @ 60 Hz for the Samsung UN65JS9500 when the port is in UHD mode. Therefore, the signal is not up-converted, but natively generated 4K @ 60 Hz. However, the signal will not show on the TV. Take the TV out of UHD mode, it shows, with a resolution of 3840x2160 @30 Hz. From what Marantz tech support told me, the Marantz is seeing the TV is capable of 3840x2160 @60 Hz and sends that native signal, but the cable will not allow the signal. This was verified by our local home theater company.
The MyCableMart tech rep was very nice and told me that they were assured by HDMI.org that any HDMI cable rated high speed and under 15ft will properly negotiate 60 Hz, Redmere or passive. He said that any cable that is Redmere active up to 20Ft will properly negotiate 4K 60 Hz. Anything over 20 ft, they have been told by HDMI.org will not work, and even then, some are questionable. 30 Hz and below 4K signals are unaffected on the cable lengths I have of 35ft and 40ft. Now, is this the fault of the cable or the Redmere chip? I don't know since Monoprice won't give up the ID of the chip in this cable #10767
. If it's the same PRA1700 chip, it could be that Redmere is at fault. If it's a different chip, from 2014, then it could be that HDMI.org is in the wrong and MyCableMart marketed it as compliant with 60 Hz since they were told it was OK to do so by HDMI.org.
Regarding Roku 4 that was mentioned by Danbfree: if the Roku 4 is right next to the TV and connected by less than 15ft, then 4K should be fine as you have stated. I don't now about going through 2 different cables, one to an AVR and then out from the AVR to the TV. I guess as long as the total length is less than 15ft, but this is above my pay-grade.
In summary, if you are looking for an HDMI cable to future-proof for 4K @ 60 Hz and the run is over 15ft, then the Redmere chip cables Elite from MyCableMart and #10767
15ft from Monoprice will not work. And it seems that MyCableMart will not honor their ltd lifetime warranty and replace the cable once they have a solution. They are only offering a refund if I send these cables back to them right now. Since one TV is too far away to run a cable across the room and down floor boards and my wife would balk at a cable across the room for the other TV, I am left with having to keep the cables in place for 30 Hz for now and pull them and replace them once HDMI.org gets their new HDMI 2.0 certification process in place and these cables hit the market.
I'm not going to get into a shouting match with MyCableMart, nor am I going to advise anyone to stay away from these cables. In the grand scheme of life, $160 of insurance money was wasted on these cables and it won't break me or the bank. I'm just putting the info out their so others can make an informed decision.
