ResChange was created to work around the fact that my (ex-)school had locked the students out of Display control panel thereby stranding them at 800x600. To get around this, I wrote ResChange, a tiny footprint command-prompt (not DOS) program, that temporarily changes the screen resolution while the program is running. You can even change the refresh rate of the screen. If you change to the same resolution all the time, then you have the option of creating a settings file that gets ResChange to set the resolution automatically.

ResChange does not depend on anything besides Windows itself, so there is no installer, so you do not need administrator's access rights to use it. Which is good since you probably don't have admin access rights since you don't have the Display control panel.

 

ResChange was the first program I wrote that used Windows APIs in C++. I wrote it back at the beginning of 2004.

System Requirements

Windows 98/ME/2000/XP/2003 or later (NT has not been tested upon).
The minimum specifications for the computer can be anything as long as the computer can reasonably run the operating system.

For an example, if you wanted to change your resolution to 1280x1024 at 75Hz this is what you'd do:

1) Start the program.

2) Input 1280 for the x-resolution. Press Enter to continue.

3) Input 1024 for the y-resolution. Press Enter to continue.

4) Input 75 for the refresh rate. Press Enter to continue.

5) The resolution will now be changed if possible to 1280x1024 at 75Hz. The resolution will stay this way until you close the program by typing something and pressing Enter.

 

Using the Settings File

The settings file will get ResChange to set a resolution as soon as you start the program, without you having to input anything. This is useful if you are constantly changing to the same resolution.

If you wanted to change to 1280x1024 at 75Hz using the settings file this is what you would do.

1) Create a blank text file in the same directory as ResChange and call it "Settings.ini". Make sure it is not called "Settings.ini.txt" by mistake.

2) Open it and put in the following:

3) Save and close the file and then run ResChange.
