A:Answer I don't know about all those sku numbers, as I haven't researched them; however, with every wall mount I've done, I just first made sure the form and function was solidified. Next, I made sure the articulating mount was compatible to my tv dimensions and weight limit. Finally, and most importantly, make sure the Vesa standard is covered (e.g., vesa standard up to 700x700), means all lower standards are covered too. (I.e., vesa 400x400).
