When I use the 1.2.9-win32 SDL.dll to set the videomode my monitor blanks and complains it is forced into 85hz overdrive. When I substitute and older SDL.dll, I have no problem. (don't know the version nr of the older dll that works, but it is 220kb.)

I am using a philips 170b monitor.
XP OS.
DevStudio 6.0

the code i use is this:

#include "SDL.h"


//The attributes of the screen
const int SCREEN_WIDTH  = 640;
const int SCREEN_HEIGHT = 480;
const int SCREEN_BPP    = 32;
#define GAMENAME        "World"


SDL_Surface *screen = NULL;

int fullscreen = 1;


int main( int argc, char* argv[] )
{

    //Initialize all SDL subsystems.
    if( SDL_Init( SDL_INIT_EVERYTHING ) == -1 ){return -1;}

    //Set up the screen.
    if(NULL ==(screen = SDL_SetVideoMode( SCREEN_WIDTH, SCREEN_HEIGHT, SCREEN_BPP, SDL_FULLSCREEN))) {return -1;}


    //Apply the background to the screen
    SDL_FillRect(screen, NULL, 0xaaaaaaaa);

     //Update the screen
    if( SDL_Flip( screen ) == -1 ){return 1;}
    
    //Wait 2 seconds
    SDL_Delay( 2000 );

    SDL_FreeSurface(screen);
    
    //Quit SDL
    SDL_Quit();

    // Body of the program goes here.
  return 0;
}
