[Q]physical screen size?

Hello, I’m using photon library and I’d like to know physical screen size of
the connected monitor.

In Windows platform, I can use GetDeviceCaps to determine physical monitor
size with HORZSIZE and VERTSIZE parameters. so can I know the physical size
in QNX 6.3?

With PgGetVideoModeInfo(), I can find the width of the mode in pixels and
other stuffs. but monitor size info isn’t there.

So any idears?
