Has anyone done an 85" corner mount? What mount can I use?

Sanus VLF628 is what I’ve used in the past. Or a Chief equivalent.

Hmmm I was thinking a 30" extension would not be long enough to center an 85 in the corner?

Due to the length of arm that would be needed, you are not going to find a mount like what you are thinking.
In order to do what you are wanting, you either have to use a ceiling mount to get the TV where you need. Or framing is going to have to be built in the corner to accommodate this setup.

What you are wanting is absolutely 'custom'. Putting a TV that size in a corner of a room, is not something most people would want to do. If for no other reason, the amount of dead space that is going to be behind that.
Has anyone done a cardboard cutout and seen just how much room that is going to take up by trying to corner it?
Doing the math = an 85" TV is going to come out at least 60+" down each side of the wall (Assuming 90° corner). You will lose 5 feet of space in that corner of the room.

You’ll also have a rather significant moment force on that wall.

We recently mounted a pair of 85’s in a bar. The architect’s idea was that the wimpy metal studs would support the pullout arm mounted TV’s. We convinced the GC to add some plywood, but his idea was to add a couple small pads for each TV and they were poorly located.

Fortunately, there were no depth issues and we could add a full plywood base, spanning multiple studs, behind each set.

Dead space no issue. It's a huge 8 car mave cave. There is now a 75" dlp sitting in the corner on wrap around shelves. Sounds like I will get a carpenter involved . Thx

Nope, that won't do it.

Take a look at how wide that 85" TV is (75" wide).
Then think... you are going to need 1/2 that distance minimum to reach a wall (37.5"). Almost an inch to short.

My original guess was off. The TV would actually come a little over 53" down each wall (assuming 90° and touching each wall).

The framing should be easy. Just build triangular frames to screw to the studs in the corner, that has a 3/4"-1" thick plywood facial mounted to the front. Then just about any arm mount should be able to reach.

[edit] Personally I would do a ceiling mount. Way quicker, easier, and more versatile.

This math seems correct using a triangle calculator. Ceiling mount I'm not sure about, would need some extensions to get it down to a suitable viewing height. The ceilings are quite high and there is seating about 15ft .

I'm not saying you SHOULD use this mount, but in theory you could. Since it reaches 40", you could mount it on the side wall and still get enough stretch to mount the TV at a 45 in the corner. That's a lot of torque though! Depends on how heavy that TV is.

Probably better to frame some support but if you feel like rolling the dice:

For mounting an 85" TV in the corner almost an inch off is a winner. I guarantee it will look great.
