Question

如何锁定刷新频率，进入游戏也不改变。

Answer 1

//更改刷新率,成功调试
//Return values for ChangeDisplaySettings
// DISP_CHANGE_SUCCESSFUL          = 0;
//  DISP_CHANGE_RESTART             = 1;
//  DISP_CHANGE_FAILED              = -1;
//  DISP_CHANGE_BADMODE             = -2;
//  DISP_CHANGE_NOTUPDATED          = -3;
//  DISP_CHANGE_BADFLAGS            = -4;
//  DISP_CHANGE_BADPARAM            = -5;function ChangeDisplayFrequency(dwFrequency:DWORD): LongInt;
var
  DeviceMode: TDeviceMode;
begin
  EnumDisplaySettings(nil,Cardinal(-1), DeviceMode);
  DeviceMode.dmDisplayFrequency := dwFrequency;
  Result := ChangeDisplaySettings(DeviceMode,CDS_UPDATEREGISTRY);
end;//得到刷新率
function GetDisplayFrequency: DWORD;
var
 DeviceMode: TDeviceMode;
begin
  EnumDisplaySettings(nil, Cardinal(-1), DeviceMode);
  Result := DeviceMode.dmDisplayFrequency;
end;//改变系统分辨率
function Resolution(X,Y:DWORD):LongInt;
var
DevMode:TDeviceMode;
begin
  if EnumDisplaySettings(nil,0,DevMode) then
   begin
    DevMode.dmFields:=DM_PELSWIDTH Or DM_PELSHEIGHT;
    DevMode.dmPelsWidth:=X;
    DevMode.dmPelsHeight:=Y;
    Result:=ChangeDisplaySettings(DevMode,0);
  end
  else //非法的失败
    Result := -1;
end;
