Question about AOC AM420B

well it depends on what you speak...the clamp is absolutely no problem. but the arms that supports the screens depending on how you place them will touch the wall. For example if you want you screen placed near the wall, the arm will certainly go beyond 5 to 10cm after the border of your table.
I might work, but be conscious that it might not, but it all depends on what you want for the screen placement

I can confirm what baaronkun said

There's plenty of room - the plate protrudes a maximum of 1.5 cm from the wall and the clamping bolt is located underneath.
