I've done a lot of reading and searching, but I'm having a terrible time tracking down a consistent answer.
I need to do a 40' in-wall run, from the wall behind my Denon 2313ci to the ceiling where I plan to mount new 1080p projector (Epson 8350, which I won via the Worst Install Mistake contest on this site!). Actually, the run is more like 32-35 feet; I've left some margin for error. My plan is to install wall jacks on both ends (the kind where you plug a male cable into the backside of the jack), and then run short (e.g. 18") cables from my receiver to one jack, and from the other jack to the PJ. My BD player and receiver are both 3D capable, and I want the cable run to support that in case I ever buy a 3D projector.
The only piece of information I feel like I've really pinned down is that I should pick a High Speed cable, since the run is more than ~10 feet. Since it's in-wall, I want to be as future-looking as possible, so choosing one "with ethernet" seems wise. Again because it's in-wall, I know I need something with a CL rating for that purpose.
I'm familiar with the nature of digital signals, so I'm fairly confident that I don't need to buy one of the $140 cables; I'm looking more at the ones in the $30-50 range on Amazon and Monoprice.
So, here are my questions:
1. What's up with Redmere? Thinner cables with smaller radii would be good for in-wall routing to make the 90-degree turn behind the jacks. Or should I just get a cable with 90-degree ends?
2. Some cables seem to be directional; can someone explain that? That seems inadvisable for an in-wall setup, although a wall-to-ceiling run like what I'm doing seems unlikely to need to send signals the other way.
3. Does my plan to daisy-chain three cables through the wall plates pose any complications?
4. Should I care about whether the cable I buy is 22, 24, 26, or 28 AWG? I understand the concept of wire gauge and its inherent effect on current capacity, but I know nothing at all about the current demands of an HDMI link. Again, for an in-wall setup, I am tempted to go with the largest (numerically lowest) wire gauge I can find that meets my other needs.
5. Should I care about ferrite cores? If so, should I try to find a cable with integral ferrite cores, or can I add them to whatever cable I choose?
6. Given the plan I've described, am I missing anything?
7. The only cable I can find that meets my needs is a Redmere from Monoprice. Amazon doesn't seem to have anything longer than 25', and all of the non-Redmere stuff from Monoprice is either too short or not High Speed. Am I missing something here?
Thanks in advance for any advice!
