Yes, the joints can be rotated 180⁰ from back to front. At some point, however, the monitors are up against each other.

I don't think the mount is robust enough for constant back and forth adjustment. The joints seem to be designed more to maintain the desired setting permanently.
I think that if you need to make constant changes, you need a more expensive mount.

Hi, moving forwards and backwards and tilting works - moving up and down only works if you loosen the bracket. Greetings
