Windows "Though Windows 7 doesn't quite have the same experience when it comes to resolution and scaling control as OS X does - it can be a bit of a chore to get it just the way you like it - it's still quite useable on the Retina MacBook Pro's 15" 2880 x 1800 pixel screen. I recommend running Windows at full resolution with the 150 percent scaling setting - that seemed to give the best overall usability. 'Retina' class desktop displays are still a relative rarity today, so it will be some time before software developers adapt applications to best take advantage of such a resolution. In the meantime, you should have no trouble running Windows on the Retina MacBook Pro if the need arises." A look at how Windows 8 handles the display would've been nice, too.

RE: DPI handling in Windows

The are basically two different categories of applications in Windows when it comes to resolution scaling: those that are DPI aware and those that aren't. Only applications that explicitly call SetProcessDPIAware are considered DPI aware.


Microsoft changed that starting with Windows 7. SetProcessDPIAware is deprecated and not recommended; instead, DPI-aware apps are to declare themselves as such in their manifest. One can hard-code DPI=true XML code into their manifest, or, starting with VS2010, devs can check the "DPI-Aware" checkbox in the manifest panel. [/q]

If an application IS DPI aware, then it is the application itself that does the scaling. So all those screenshots are applications that declared themselves DPI aware and yet failed to implement it correctly.


I think the problem here might be that (pre-Metro, at least) Microsoft's "high DPI" SDK documentation focuses on 150% DPI. The Windows 7 SDK documentation says, "The standard DPI settings are 100% (96 DPI), 125% (120 DPI), and 150% (144 DPI). The user can also apply a custom setting. Starting in Windows 7, DPI is a per-user setting.", so developers of DPI-aware apps target those DPI settings (adjusting their code and providing graphical resources (like icons) for each of those DPI settings). But Retina display is 200% DPI, so lots of DPI-Aware Windows apps wouldn't handle that in optimal fashion.
