I have a Studio Display and would also love if it had a much higher refresh rate, but only because I play WoW on it. Why isn't 60hz enough for programming? I don't think I notice the refresh rate at all when not playing a video game or watching videos.
I'm personally not very sensitive to refresh rates, I only really notice it in video games and it wasn't enough to keep me from replacing my 120hz primary monitor with the Studio Display. I was just curious about why you prefer higher refresh rate for programming, thanks for answering!
