I'm actually looking, in general, to see if there's a technical group at LG that can answer questions that an installer would find simple, but which their help line had a hard time comprehending.

The question is, on a 65UN7300PUF, what is the vertical spacing of the mounting holes from the top of the TV or from the bottom of the TV (without the legs in place).

There are two manuals available for this model, and the same drawing can be found in both, which shows a 300x300 VESA mount; notes how far each edge of the TV should be from adjacent surfaces; and has ZERO information as to how far down the VESA holes are from the top of the TV (or up from the bottom).

I want to get the mounting location worked out in detail before I open the TV. It's as simple as that. Criticize that if you will, and if you want to waste keystrokes....


Thanks for any help you can give me here.

Sign up for Reachlg.com. All of the CAD drawings are there.

Is it surprising or just par for modern business that the LG tech support people you can find just by googling have NO IDEA that those sites exist?

LG Tech support is pure consumer support. There is a a dedicated team for CI support...we are a tiny piece of the pie...and truthfully LG's commitment to the CI community is only 2 1/2 years old.

Jack, can you supply Ernie with LG stuff? I'm of the opinion that dealers should buy from folks who support them...

Nope...I am regional only in Midwest and Mid Atlantic. But I do believe in supporting the community that helped me in my early days. Although smaller than 10 years ago this is still an amazing resource.

Thanks, everyone.

Before I saw your helpful responses I ended up taking the carton off and measuring, using a contractor's square held in place over the top of the TV. Nice to see that worked: the dimension I measured was.020" off from the dimensions on the drawings... it was just a metric to English conversion difference!

Nice to know that data is out there. Thank you so much.

Why would you use such a coarse measuring tool for this?

Just by looking at the back of the TV, the holes are spaced very close to increments of 1/3 of the total height (without the feet).

For future applications when you can't find the drawings-

Have you ever heard that you can find dimensions on a photo when you use a known dimension as a reference for finding the proportions? It's best if you have a compass (the kind for drafting, obviously) and a ruler/drafting scale with fine increments and a printed copy for this.

When I put a standard square up against the TV, I got a number within a sixteenth of an inch. That's better than "coarse," and good enough for me!

It's odd that, while you slam a square as being coarse, you suggest that just looking at a photo might tell me where the holes are. Meanwhile, I'm looking for the exact mounting height, not just what you can approximate without using ANY measuring tool.

If I had a photo but no electricity I'd use the method you suggest. I'd use a divider instead of a compass, but hey, details.

If I had electricity (and I often do), I'd use Paint to display the photo, make it reasonably large onscreen, count pixels and do some arithmetic (it doesn't even rise to the level of being called math) to determine the needed dimensions.

By the way, did I mention that the strangest thing happened? This 65" went up where we had a 42" plasma, putting the TV exactly where we wanted it, without moving the bracket at all!

How did you determine that it was .020" off by using a carpenter's square? 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)?

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.

You could have counted pixels but then, you wouldn't have needed to post the original question.

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?

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.


It's marked in eighths.


I didn't miss it. Neither did I have a photograph of the back of the TV.


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.

I google searched the model and found a photo in about ten seconds- why didn't you have a photo?


I think we have commented on this before- cabinetmakers can be a real PITA. They ask for equipment dimensions and make the space 1/8" larger because "It fits", which shows a complete lack of understanding. I did have one guy ask what I wanted for the space- he actually asked if I needed slots in the shelves, for ventilation. I almost passed out.

I'm really tired of hearing people say "I can't" do something when acquiring what they need can be very simple, as you demonstrated by giving them the rulers. I'm waiting for one of them to say "My CNC router is accurate to 1/4 inch.".
