Yikes - That's exactly the fear on the "2 panels in 1" type of Monitor setups. Glad warranty has you covered!
I think I'm waiting for 5k to come to a single panel and single cable solution.
Not so far....hope it still comes.
I have the same monitor in 4k and would LOVE 5k at this size. Think it's the perfect size for perfect 2x (so 1440p basically, but everything silky smooth looking)
