Hi, you can customise the stand to all sizes. If the Sharp has 4 screws at the back for wall mounting, this will work.

I mounted a Samsung Odyssey G9 Curved , so i think you will have no problem

Yes goes.

No, but the manufacturer says: Lockable swivel castors allow portability and quick and easy adjustment of the screen angle.

Unfortunately, we do not have any real empirical data on this. We have forwarded the question to our community and hope that a user can provide input.

I just saw the question, it was 12 months ago. But the manufacturer's specification of 60 cm inside is correct if you take the screws into account. The metal stand has a width of 4 cm if you take into account the rotating rollers that move out sideways when manoeuvring, the 75 cm is good.
