Digital Light & Color

It's probably not the right place to ask, but still interesting. My native screen resolution is 1920x1080 and is set as such in Windows 10. But the monitor is a tiny 11" and to be able to read anything I need to scale the text up in Windows. That seems to scale images in PWP7 as well (I discovered that they were not displayed as pixel-per-pixel while using gamma test images), but not in PWP8. How does that work?

I think I fixed the issue by disabling the display scaling for PWP7 in its Properties/Compatibility tab. The icons are tiny, but the images display correctly now.

When you let Window scale an application, it magnifies everything, including fonts, icons and images by resampling the entire screen. For large high-dpi screens, this makes the fonts and icons legible but blurs images. PWP avoids this by registering as DPI-aware (new mostly in Windows 10) so it handles its own scaling. This lets it draw fonts and icons large while preserving the full screen resolution for images. PWP has a separate setting (File/Font Size) to let you make text and icons larger or smaller. Non-DPI-aware applications let Windows handle the scaling via the Display control panel. PWP7 in not DPI-aware.
