Mounting a TV on a slanted wall/ceiling

While I figured this would be a more widespread thing with more available solutions, my Google searches are not coming up with anything that seems super reliable. We've got a family room in the upper floor of our house that is a half/loft floor. The walls come up for about 4 feet (a "knee wall") and then go at about 45 degrees inward to meet with the ceiling. We recently got a new 65" TV that I'd like to mount on one of these walls, with the ability to articulate its angle as much as possible, but also be sturdy. We'd set up our seating at the opposite end of the space (enough distance for a 65" screen).

Have people mounted a TV in a situation like this before? Is there a mount that can be used directly or, as I've seen some suggest, do you need to build a custom carpentry piece that the TV mounts to and that piece mounts to the wall?

I believe there are TV mounts with very good articulation that will suit your needs.

In terms of anchoring it onto your angled wall, perhaps go to a hardware store to see what you can use in lieu of screws that come with the mount?

Something off the shelf will be tough to find. If you mount on the sloped wall/ceiling (whatever you want to call it), the articulated arm will naturally want to extend with the force of gravity so you need something that couterbalances. Tilt mechanisms (45 degrees is pretty tough to find) is usually at the TV end (away from the wall) and you need the tilt at the wall. Someone can fabricate one but it won't be cheap.

Other thing you could look for is a fold down mount if you can do without turning, assuming one exists.

This is just from Pinterest and not our space (which is still being renovated), but the idea is similar. In our case, the lower part of the wall that goes straight up (the "knee" wall) will be 4ft in height. The TV may hang higher or lower on the slanted wall, this is just an example. Also, for what it's worth, we are renovating and refinishing this space, so could build something in with the joists/studs, if it helps.

You could get an articulated arm with the longest possible extension and mount it as far up the wall where the TV can still fit (size isn't your friend here and could impact how high you can mount the TV and how much you can angle it side to side.

You'll need to draw out the wall (pony wall is what I've heard it called), ceiling, arm length and TV height and see if it'll even fit.

I'd double or even triple up the wall studs where the mount will be (not necessary but since the arm will most likely be fully extended, the TV weight will result in a lot of moment that will stress the top bolts on the mount. Use the highest grade and longest lag bolts (3 1/2-4"? Longer if you have 2"x6" construction.) The TV will, until you remove it, stick out quite far from the wall unless it is close to floor level (rather convenient).

Most folding TV mounts unfortunately only support up to 55", it appears.
