operating system - Is it possible to detect if the hardware display has completed the process of switching between display modes? -

-

the reason ask because bought new lcd takes approximately 5 seconds change between display modes, such 1920x1080x32bpp 1280x800x32bpp. programmatic solution exist detect if display ready video output?

i believe answer 'no'. once display adapter starts transmitting new signal in new refresh rate, etc., has absolutely no way of knowing how long takes display internally process change , start showing image. hardware limitation both dvi , vga signals, not software one.
