Yes, if you have your windows set to 150% at this moment in time there is no way to run cubase at 4k native (full resolution)
you have to drop down to 125% then log off and back on, right clicking the exe and choosing ignore dpi settings does nothing anymore…
If you want to use full 4K without the limitations “too small”, we need to use at least a 45- 50 inch monitor. Only then are all the pixels again at about 90 ppi as in the past with the usual screens. Otherwise, the graphics must be scaled, so that the benefits of 4K are partially lost again.
It unfortunately does not work in the same way as 9.5 when you disable HiDPI, it locks to 200% when you disable HiDPI (or presumably whatever you have your scale value to, and there is no way to disable this. (that i have found))
No, Windows 7 and Windows 10 have totally different HiDPI implementations. For example there no support for multiple displays with different DPI on Windows 7, but that’s only one of many things missing in Windows 7.
Most of Windows-API features are cumulative. So everything available in Windows 7 is also available in more recent Windows versions, so support in W7 and W10 cannot be totally different, it can be just extended in W10.
Per-Monitor DPI Awareness is not as important as support for HiDPI itself. For basic DPI awareness, all you need is:
determine pixel ratio by dividing GetDeviceCaps(GetDC(window), LOGPIXELSX) by default 96;
multiply all the UI-element’s sizes and coordinates by that ratio with proportional upscaling of bitmap graphics where needed;
declare DPI awareness: either via executable’s manifest (<dpiAware>true</dpiAware>) or by calling SetProcessDPIAware().
Or does Cubase 10 use Windows 10’s automatic scaling stuff like EnableNonClientDpiScaling() without actually supporting true HiDPI?
Fwiw, according to StatCounter, market share of Windows 7 is 70% of Windows 10’s market share (36.31% vs. 51.94%). According to NetMarketShare, the difference is even smaller: Windows 7’s market share is 84% of Windows 10’s one (35.27% vs. 41.82%).
