http://help.adobe.com/en_US/FlashPlatform/reference/actionscript/3/mx/core/RuntimeDPIProvider.html I have tried this on Flex 4 application(4.13, FP15, AIR15) and I'm afraid it isn't working as expected. I tried to create a runtime class and DPI value was overridden. But still there is no change. All screen elements look very small than normal.
Has anybody come across this case on laptops(high DPI\retina display\HD)? On iPad retina display, it works out of the box without any runtimedpiprovider class when I use flex 4.13 but not on this laptop. When I checked Capabilites.screenDPI, I get the value as 72. Looks like value returned isn't correct nor is it getting overridden. Any ideas? PS: I'm testing this on Dell latitude E7440.
