It makes a huge difference, using 30Hz for any lenght of time is tiring
What I am looking for is someone who has actually USED C7 on a 4K monitor, not just opinions. Anyone? So far no takers.
Given that the cheapest 4k monitors are around 4000 euros I doubt many, or any, are using it as cubase monitors (the budget TV’s will not really make it as monitors due to lack of suitable interfaces, which will also limit their effectiveness as 4kTV’s or with UHD discs in the future, only the Sony TV’s are suitable as monitors and they are expensive)
I have used Cubase 6x with an IBM T221 at 3840x2400 (WQUXGA), actually a slightly higher resolution than 4k, a few items became too small for comfort but that monitor is fairly small, I imagine that with a monitor that is a whopping 80cm from corner to corner (ca 31") like those cheap 4k monitors this will not be an issue, and with Steinberg slowly but surely making the program scalable this will not be an issue in the future, regardless of resolution.
