Thanks for that, you are spot on.
I was going by the picture of the rear of the screen in HH's article which appeared to show a fully molded back with no such option.
Turns out that in LG's higher quality pictures you can see there is a very close fitting plastic form that hides the VESA mounting option quite cleanly.
Very nice

Shame to see they removed the VESA mounting option, I have my current 4k LG 27" mounted on a very smooth gas strut arm and it is so much more versatile. Even a well designed stand cannot come close.
