Hi Wij,
I use 3 separate wall brackets, not a desk stand. They give many more mounting options that one fixed stand. I can really adjust them the way I want rather than a fixed position that a desk type stand would give.
The are LCD107's and can be found searching Amazon.
At present the advert doesn't mention 24 inch screens, but it used to and they fit mine perfect. Though it is a ball ache to get the 3 arms correctly positioned on the wall and correctly drilled.
