[Dev-C++] allegro and liquid-crystal-screen

[Ricardo_Lopez <ri...@un...>]

"void vsync( )" is a function in Allegro library
to write on the graphics card during the retrace interval
of the electron beam in a monitor ....

but how can I do the same with a Liquid Crystal Screen (LCD)??...
the system refreshes automatically the screen and the graphics is lost....

why??...how can I avoid of losing the images in a LCD  ??.


any help is strongly appreciated.
