55" is huge! Is that a typo? One of the big box electronics stores (not sure if I am allowed to name names, but it has a big yellow price tag as its logo) is still selling the Dell 24" touch screens. They are pricey--I was able to snag them on a big sale a few months ago--but I am very happy with them. They certainly are large enough, almost bordering on too big.
That Dell model also accommodates sound, but I don't use that. I use a quality audio interface (MOTU M4), disable all other sound drivers, and mostly use headphones, or occasionally, bookshelf speakers.
To answer your question, yes, if the Dell specs say you can use a 100mm mount, the stands will come off. Mine did exactly that. The screens are easily mounted to an arm or monitor mount, and I have used them in both portrait and landscape orientations. The stands themselves are very heavy, but the screen without the stand is not heavy at all (like a standard computer screen or very small flat TV).
