i have found the register key that has the resolution information in it, and i am able to change it. the problem is that even if i do an EnvUpdate, it doesn't really change the resolution. the reg says it is what it to be (800x600), but it still is at what it use to be (1024x786).

does anyone know how to get the change to be updated so the resolution will change?

Maybe you must close and launch Explorer,

Or call a command-line resolution changer?

sweet multires!

Numpad0 & Numpad2::run, E:\Program Files\MultiRes\MultiRes.exe /800`,600`,32`,72 /exit
Numpad0 & Numpad1::run, E:\Program Files\MultiRes\MultiRes.exe /640`,480`,32`,72 /exit
Numpad0 & Numpad3::run, E:\Program Files\MultiRes\MultiRes.exe /1024`,768`,32`,72 /exit

Just wanted to share how I do this on XP SP2 with an LCD monitor (no refresh rate issues). This changes the display to 1024x768. Perhaps this would help someone not wishing to install multires

Yes, but I don't think the refresh rate can be changed using EnumDisplaySettings.

Alan,

That's a sweet script. It was just what I was looking for. Although, since this is way over my ability to understand how it works, how could I restore my resolution to the previous setting?

Basically, I'd like to run switch into 800x600 mode, run some program and then switch back to the original mode. Furthermore, if my screen is already 800 x 600, I'd like the script to exit the function.

I figure I've got to get something to read the current settings and save it to a var like OldHEIGHT, OLDWIDTH and just run the function again. But I guess I'm not understanding the DLLCall, all those parameters and the ret := and how to store/retrieve the right info.

Thanks in advance.

Hmmm... here's another thing that I don't understand:

So I take Alan's code and wrap it in my function

SetScreen800x600(){ above code lines here
}

Then in my script hotkey script, I've got

+^!F11::
ifWinExist, MyApp
SetMonitor800x600()
WinActivate, MyApp
SetKeyDelay, 0, 10
Send, +^!F11
SetKeyDelay, 0, 0
Return

The monitor gets switched but then nothing else happens. It looks like after the SetMonitor function runs, the WinActivate gets lost during the monitor switch.

Since you said that the switching of the Res is working, I think you are a bit off topic here. You should have posted it in your own topic (I just answered).

It may help to add a Sleep after the SetMonitor() and maybe to increase the values of setkeydelay to high values, e.g. 100. If that works, then you can start to decrease them.

Here is another pure AHK solution, by manipulating the Windows Display Properties/Settings dialog.

This method does have the advantage of not needing a 3rd party utility, but in my experience command-line tools almost always work better, and are more reliable than sending keystrokes etc...
