Sorry, but… If their ads are showing 4K screens in action, it’s that the HiDPI is more or less functional, unless all have been done under OSX : I don’t know, I haven’t check. Beside this, I don’t deny the need for certain professional applications but again, I think that what Matthias Quellmann said on the subject should be carefully read and am rather skeptical about the absolute ‘need’ for a professional 4K/HiDPI use of several whiners on the subject : we all know that jumping on everything appearing as a brand new technology, no matter the pitfalls that could appear, is not a marginal behavior…
See above : to make things as short as possible, read again Matthias Quellmann…
I don’t know if using a HiDPI setup is such a nightmare and obviously, I’m not in a position to test it. So, could you post links to screenshots showing these issues ? I would like to see by myself to which point they prevent any use of Cubase on a daily basis. Until now, I haven’t seen one clearly showing that it’s the case…
