Elgato says it's just fine to have multiple stream decks connected to a single PC.  I have one XL working great, if I were to buy another XL would Axis and Ohs work with both?  I plan to use the same profile on each deck, just with different "pages" of the profile open on each deck.

I have an XL and a Standard - works fine - I use aircraft profiles on the XL and views on the standard - never tried using the same profile on both at the same time but I don't see why it wouldn't work.

Thank you!  I'm off to the shops.....

I have 2x XL's, same profiles on both of them cause no problems
