Need recommendations for desk mounting arm and VESA mount to use on a 42" monitor

Well i'm planning to get a WASABI MANGO UHD420 so I'm looking for a proper desk mounting arm and VESA mount (400mm x 400mm) which will be able to support the weight of the monitor (29.3 pounds/13.3kg), I have no experience whatsoever in desk mounting arms so I need recommendations. Cheers lad.

Use what @wendell uses - cant remember the name but its in a TEK video! Will update when I find it.

If you meant by the Ergotech 7 Flex HD video, yes I have already watched it, sadly it uses 75x75mm and 100x100mm VESA Mount, any other recommendation?

Does it have to be a desk mount? or could you use a wall mount?

Maybe something like this?

rated for 35kg not exactly VESA but it should do the job

Yes sadly it has to be a desk mount since I'm having my room layout changed and just for the sake of convenience, I wouldn't want to drill holes into my desk or wall, thanks anyways.
