I used to fool with this fancy soldering when I was younger. I even fixed a core storage array once but these days I am more of a "200 watt Weller" guy.
Even the sub D connectors like you have on a monitor are a challenge to me. If someone will sell me a cable with molded ends for five bucks, I am buying it.
I do crunch ends on cat 5 cables now and then but I even like to buy those if I can.

Do they make HDMI cables with jacketing that is actually rated for installation within walls?
I hear a lot of buzz about them not being Class 2 rated , so can’t be run in walls or ceilings, etc... but how else can you get them behind a wall mounted flat panel TV?

I looked at all of the cables going in the back of my big screen (almost every port has a cable) and the only one with a "CL" rating is the coax. HDMI, component, A/V, PC audio and the VGA cable are unrated.
I suppose the "safe" way would be to run a sleeve of 2" ENT or other raceway to pull the cables through. That still may not be "legal".
There is a good chance that any name brand cable would meet the flame/smoke test for CL2 but they don't seem to be marked.
OTOH if you are talking about some offshore cable, who knows what the insulation is? If they do get rated, it is only for signal quality. I have always been skeptical about the "in wall" systems sold for big screens. On the line side, they are basically just an extension cord inside a wall. They are largely beyond the inspection process since they are homeowner or "TV installer" items.

It never ceases to amaze me what people will pay for digital signal cables. Just 1s and 0s as long as they arrive at the load in the same order they left the supply we get reliable data cable.
I have a local electronics wholesale that sells HDMI cable for $10 and $80. One has a big Audio brand name. Dispite his recomendations to customers he still sells a lot of the $80 ones.
Take a European house panel and gold plate the neutral and bonding terminals and you can sell them to Audiophiles for $3000. A 10 fold markup for absolutely no benifit and no recognized electrical approval or listing for use in any North American market.

I did some poking around and it looks like these guys apparently have the CL2 and CL3 rated HDMI cables. The one in the link says 20m, so I assume that means 20-meters or around 60-ft in length. If so, the price doesn’t really seem too bad. Dayton HR13HG20 High-Speed HDMI Cable 20m CL2

I have always been skeptical about the "in wall" systems sold for big screens. On the line side, they are basically just an extension cord inside a wall. They are largely beyond the inspection process since they are homeowner or "TV installer" items. In Canada we look for FT-1 or FT-4. Both are flame spread tested one is for combustible buildings and four is for non combustible buildings. FT-6 also exists and is mandated in some jurisdictions for wiring in Plenum spaces. In the absence of FT or CL ratings it is perfectly acceptable to install in a rated raceway like ENT or EMT. the wire inside is considered rated too.
