Monitor desk mount question.

[leelaa14]

So I'm gonna pick up this desk mount https://www.amazon.co.uk/Invision®-Monitor-Arm-Gas-Assisted-Adjustable-Black/dp/B0765Y4CT5?SubscriptionId=AKIAJ4EYSZSNXUGA7B6A&tag=sysrebyor-21&linkCode=xm2&camp=2025&creative=165953&creativeASIN=B0765Y4CT5 and I see a few people mount their arms off centre. Is there a reason for doing this?

The arm would hit the wall behind it if it wasn't angled off to one side but you can just readjust it to be centered if you want it to be so.
