AFAIK, forms created from resources are drawn in legacy (160x160) format. On 
hires screens, controls and other UI objects have each of their pixels 
quadrupled (in 320x320 resolution that is).

Hires is useful if you do graphics. You just call
WinSetCoordinateSystem() with the proper density constant such as 
kCoordinatesQuadruple (it must be supported by your screen, as determined by 
WinGetSupportedDensity().)

After that, all Win procs such as WinDrawChars operate with hires coordinates. 
Don't forget to go back to lowres when you're done drawing so that the OS finds 
the screen in legacy res if it needs to draw a control or pop up an alert.
