Any way of changing Windows screen resolution via command line?



As an IT administrator, you may find yourself needing to quickly change a Windows screen resolution via the command line. While this is not a feature that is built into the Windows Operating System, there are some methods you can use to achieve this.

The simplest way to change the screen resolution via the command line is to use a third-party utility. There are several available, some of which are free and open source, such as “Change Resolution” and “ResChange”. These utilities allow you to set the resolution to any size you desire, as well as to save and load presets for quickly changing the resolution in the future.

If you don’t have access to a third-party utility, you can still use the command line to change the screen resolution. To do this, you will need to use the “reg” command. This command is used to access the Windows Registry, which stores all the settings for the operating system.

To change the screen resolution, you will need to access the “Display” key of the Windows Registry. This can be done by running the following command:

reg add “HKEY_CURRENT_USER\\Control Panel\\Desktop” /v “ScreenResolution” /t REG_SZ /d “[width]x[height]”

Replace “[width]” and “[height]” with the desired resolution. This will set the screen resolution to the specified size.

You can also use the “reg” command to set the refresh rate of the display. This is done by running the following command:

reg add “HKEY_CURRENT_USER\\Control Panel\\Desktop” /v “RefreshRate” /t REG_SZ /d “[refreshrate]”

Replace “[refreshrate]” with the desired refresh rate in Hertz (e.g. 60 for 60Hz).

Using the “reg” command is a fairly simple way to change the screen resolution and refresh rate via the command line. However, it is important to note that this method can be dangerous if used incorrectly. It is recommended that you back up the registry before making any changes.

Overall, while Windows does not provide a built-in command line utility for changing the screen resolution, there are several ways to achieve this. The easiest is to use a third-party utility, but if one is not available, the “reg” command can be used. However, caution should be taken when using this command, as it can be dangerous if used incorrectly.
