I'm pretty sure you can use a 2SeeMy with a 3200... they have installation instructions for that board on their website. But I don't use one, and have replaced my LCD, for two reasons:
1. No room for more displays... And if I did re-work my space for a third display, I'd use it for more DAW real estate.
2. Just don't find the LCD difficult to read it use, and certainly don't need the information it displays up on a big display.
But if you like it, go crazy!
