A few people have noticed you might end up with a slightly fuzzy display in Rhino V5 after the SR14 update.
This is easily fixed.
Run the "About this PC" command in Windows to determine your Windows version:
In Windows 10 "Creator's Edition" (1703), Rhino 64-bit desktop shortcut right-click > Properties > Compatibility > Uncheck "Override high DPI scaling behavior..."
In Windows 10 (1607), Rhino 64-bit desktop shortcut right-click > Properties > Compatibility > Check "Disable display scaling on high DPI settings"
If you still have display problems, you can run the new "SetDpiAwareness" command and disable the SR14 fix, and restart Rhino.
