| Actually I've ever used this function for TV-based software development, because of TV-resolution. { The function NewRes can have the following result: DISP_CHANGE_SUCCESSFUL The settings change was successful. DISP_CHANGE_RESTART The computer must be restarted in order for the graphics mode to work. DISP_CHANGE_BADFLAGS An invalid set of flags was passed in. DISP_CHANGE_FAILED The display driver failed the specified graphics mode. DISP_CHANGE_BADMODE The graphics mode is not supported. DISP_CHANGE_NOTUPDATED Windows NT only: Unable to write settings to the registry. } function NewRes(XRes,YRes:DWord):integer; var DevMode:TDeviceMode; begin EnumDisplaySettings(nil, 0, DevMode); DevMode.dmFields:=DM_PELSWIDTH or DM_PELSHEIGHT; DevMode.dmPelsWidth:=XRes; DevMode.dmPelsHeight:=YRes; Result:=ChangeDisplaySettings(DevMode, 0); end; procedure TForm1.Button1Click(Sender: TObject); begin if NewRes(1024,768)=DISP_CHANGE_SUCCESSFUL then begin ShowMessage('Resolution changed.'); end; end; Tags: ChangeDisplaySettings DISP_CHANGE_FAILED DISP_CHANGE_NOTUPDATED DISP_CHANGE_SUCCESSFUL Delphi EnumDisplaySettings Screen Mode Change Screen Resolution TDeviceMode
