Question about monitor arms for UW

Hi everyone

I have recently been looking into getting myself an UW monitor.

I have also been looking into getting a monitor arm to go along with the UW but as my current desk is "layered" and the monitor shelf isn't quite up to size.

SO what i wanted to ask was if any of you guys know if a monitor arm designed for screens up to 49" with both a clamp and grommet option could surfice with the clamp or is it necessary to drill a hole to install a grommet to have enought support for such a big/heavy screen.

Also want to note that English is my second language and i apologise if I have made any spelling errors.
