How did you determine that it was .020" off by using a carpenter's square?
Before the Helpfuls published the LG website URL, I gave in and pulled the top off the box and held a standard square in place. The dimension I got was just under 14 5/8". That is 14.625". Later, I saw that the dimension listed by LG was 372mm, which is 14.645". That's how I used a square and got a measurement within 0.020" of the spec.
Is this one of the rare ones that is marked with increments smaller than 1/8" (and yes, I understand that it's possible to use the space between marks as a useful increment)?
It's marked in eighths.
I wrote that the placement of the holes seems to divide the TV into thirds; my other recommendation was to measure this on a printed photo with a scale that's more accurate and check the proportions. You must have missed that because hey, details.
I didn't miss it. Neither did I have a photograph of the back of the TV.
No, you didn't mention that. Would moving the bracket up or down on the TV be possible, or does it only have one set of holes?
Every time I've mounted a 65 in at least the last year, the TV has had the 300 x 300 VESA pattern and the mount could not accommodate a TV with a larger pattern (vertically). So there's been no adjustability of TV in relation to mount.
There was at least 3 inches, maybe as much as 6 inches, of variability as to where the TV would be positioned on the mount.
As for the mounts in these cases, the other TVs I've mounted were given to me with mounts, so I don't know the model numbers... and this mount is one I've had for four or five years, so... no model number. Sorry.
This all reminds me of when I designed some car stereo displays with multiple VERY precise panels for speakers, designed so the speaker sizes could change when needed. I had some steel pieces made with PEM nuts installed at locations within 0.010" throughout, and the cabinet guys whined that the tolerances were too tight for them. They couldn't measure that closely (about 0.050" over a total of five feet).
So one day I showed up at their shop and gave them a three foot rule and a six foot rule, each marked in 64ths on one side and hundredths on the other. They shut up real fast.
