some way of detecting WM_DISPLAYCHANGE might solve it:

the WM_DISPLAYCHANGE message is sent to all windows when the display resolution has changed.

WM_DISPLAYCHANGE
cBitsPerPixel = wParam;
cxScreen = LOWORD(lParam);
cyScreen = HIWORD(lParam);


Parameters

cBitsPerPixel

Specifies the new image depth of the display in bits per pixel.

cxScreen

Specifies the new horizontal resolution of the screen.

cyScreen

Specifies the new vertical resolution of the screen.
