How can I get a negative value for the brezel in the triple screen settings? (I use the Asus Brezel Free Kit together with the Nvidia surround)
Negative? Why would you want anything drawn on both screens? (note: I may go review how the kit works and realise why...)

Solution: Press „ctrl-alt equal“ to get the triple screen settings when driving. And then you can adjust all values including having a negative value for the brezel.
