<p>Windows提供给我们两个API函数，可以动态调整显示器的分辨率，他们是EnumDisplaySettings() 
和ChangeDisplaySettings()，下面这个例子就是了<p><span class="p2">function 
DynamicResolution(X, Y: word): BOOL;<br> 
var<br> 
lpDevMode: TDeviceMode;<br> 
begin<br> 
Result := EnumDisplaySettings(nil, 0, lpDevMode);<br> 
if Result then<br> 
begin<br> 
lpDevMode.dmFields := DM_PELSWIDTH Or DM_PELSHEIGHT;<br> 
lpDevMode.dmPelsWidth := X;<br> 
lpDevMode.dmPelsHeight := Y;<br> 
Result := ChangeDisplaySettings(lpDevMode, 0) = DISP_CHANGE_SUCCESSFUL; <br> 
end<br> 
end;<br> 
<br> 
procedure TForm1.Button1Click(Sender: TObject);<br> 
begin<br> 
if DynamicResolution(640, 480) then<br> 
ShowMessage('Now is 640*480');<br> 
end;<br> 
<br> 
procedure TForm1.Button2Click(Sender: TObject);<br> 
begin<br> 
if DynamicResolution(800, 600) then<br> 
ShowMessage('Now is 800*600');<br> 
end;</span></p>
