Due to a lack of desk space and desire to want to utilize my monitors more effectively, I've been trying to figure out if the setup in this beautifully drawn picture here would be feasible. Scenario 1: The idea is that during the day while working from home I would have the 34" ultrawide directly in front of me (red line) and a 27" gaming-orientated monitor off to the side. Scenario 2: I want to be able to move the 27" monitor from the side position, directly in front of me and then translate the 34" ultrawide up so that it sits on top. I don't believe there is a way to literally switch the two monitor positions, so this is the compromise I've come up with for now. Has anyone got any similar setup, or have any thoughts on how to get this to work? It seems that any normal extendable arm mount will work for the 27", but I haven't had any luck finding an arm that can translate the vertical distance to fit the 27" beneath the 34". A note that I am in Canada so product availability may be slightly limited. Thanks all!
