I'm in the process of installing in wall HDMI wiring (along with cat6A and Coax). Due to relatively long runs 40-60ft I'm focused on cables with Redmere technology. Through my research I have found there are 3 Redmere chips. MEA 1689, PRE 1692 (10.2gbps) and PRA 1700 (18gbps). Considering I want to future proof and ensure the cables can handle full true 4k (18gbps) then the only Redmere solution would be a cable with the PRA 1700 chipset. Unfortunately I have not been able to find any cables that have this chip. All the available high speed Redmere cables advertise a high band with but have the chip only capable of 10.2GBPS. In this scenario the chip is the limiting factor not the cable. So if I'm unable to find a cable with the PRA 1700 chip would it be best to use high end non Redmere cables on the short runs(40ft - 60ft) to ensure full bandwidth? From my understanding, the only benefit of Redmere technology is a thinner cable (easier for installs) and ability to bridge a longer run. As mentioned Redmere makes the PRA 1700 (18gbps) chip however I cannot find it in any HDMI cable in the market (maybe someone can).

Accepted Answer

The only advice i can offer is going to Redmere's website and then go to the Where to Buy link and see if you can find the cable your looking for. Or alternatively you could contact Redmere and see what they have to say. hope this helps :-)
