Thanks for the response. You make a good point. I cracked the screen on my mac (part of the reason for wanting a dedicated setup) so I’ve been using Zwift on my phone or an old surface pro. The suface pro does ok for an hour or so but then the screen gets shaky. Really weird. I wouldn’t try and stream netflix to a second screen using that. I would like to experience Zwift at it’s best but you are right, once those intervals start I can’t really see straight anyway!
