Thanks again for the responses. The redmere cable (35 foot length) does have internal chips to boost the signal and it is working well to my overhead projector (SONY 40ES) but it goes directly from the output of my Panasonic bluray player. In theory, if I run the output from my bluray to the pre-amp and then from the pre-amp to the projector I would imagine the total distance is the sum of the 2 cables plus whatever is lost within the pre-amp. I would hate to buy the 976 only to learn that the signal is still too wea when it arrives at the projector and have to send it back.

Currently neither my TV or projector is 4K but I am upgrade the TV in a couple of years (it is about 9 years old) to 4 K but it is quite close to the TIVO which actually provides an HDMI cable made for 4K output.
