This unit will be compatible with Vizio TVs between 13 and 24" that utilize a VESA standard mount pattern measuring 75 x 75, 100 x 100, or 200 x 100 mm.

Mine folds pretty flat, but obviously it still sticks out from the wall some. It does not look out of place, though.

No. It's a WALL mount unit. There actually IS a TV made to be mounted under a cabinet. The unit is sold 'all in one', that is as a TV with the under the cabinet mount, 'all in one'. The TV folds back & up when not in use, almost hidden from view. It comes with a remote control and can be connected to cable, etc.

Yes, it just would need to be more on one side or the other. It wouldn't be straight back against the wall.

Yes if you have the room for it.

I don't know if you can get spacers for this mount. A better solution might be to use a piece of 2x4 between the wall and the mount. Since the wood will be behind the tv, you might not see it and it wouldn't look to bad. Just make sure you mount the 2x4 on the wall where there is a stud to secure it and then screw the mount into the 2x4 to extend it another 1 3/4".

last year I bought a Toshiba 24 in and same Rocketfish mount mentioned above. Love it. Above to tilt and extend as much I need.

Should have longer screws and spacers in pkg. You should pull the mount out from wall as far as articulating arm will allow, then you can tilt T.V. down more, I think that's what you are asking.
