I used HDMI over Ethernet for mine. It'll look unsightly regardless - you'll still have a great mass of something running along/up/down the outside walls.
Nooooo, terminate them properly into faceplates.
Ahh, if it's hidden away in like a cupboard then i wouldn't worry too much. Mine all terminate in a cupboard under the stairs, so they literally just come through a hole in the wall, the rack is high enough on the wall that it's hidden away.
I have seen 4k senders, but i think they're quite expensive, and i don't know how reliable they would be - so bit of a gamble unless you can find someone who's reviewed and can recommend.
Just round a wall or underground to a shed or garage?
What is it you are actually trying to do? Do you have the option to run the cables up in to the loft from within the house and drop them down in to the rooms you need or out of the soffits in the roof near the locations required?
Ah ok, no real easy way to do it by the sounds of it. If you go the external route, would the cables come out on the ground floor (understair cupboard)? If so you could run them low around the house to hide them until you get to a downpipe?
I have a newish build town house so my master bedroom and ensuite is in the loft. I could not get a network cable up to the top floor in any easy way. I should have run a cable last year when I had AC installed as I had scaffolding above my garage to access the loft above the master bedroom. Hindsight for you.
I have about 50mm wdith of gravel all around the back/side of my property so I actually ran my cables under that. I had to scoop all the gravel out first, and I dug down a bit deeper (60-70mm IIRC).
This is the entry point in to the side of my garage for 2x IP camera's. I've only got this pic of the one cable installed but I ran a second one (mainly as a backup). I've connected some APC gigabit surge protectors to each cable within my office (where they connect to my network equipment), just in case. The kenable external cat6 cable I used specifically mentioned you could bury it.
