Troubleshooting Kingdom's Monitor Resolution Switch Issue

The error message couldn't switch to requested monitor resolution is a common issue that occurs when a game client is unable to scale to the resolution set in the configurations or the resolution in which the launcher is trying to launch. This error message has been observed in several games, including Kingdom: Classic, Ori and the Blind Forest, Hollow Knight, Slime Rancher, Hearthstone, and Elderscrolls Legends. Several solutions have been suggested by users, including disabling full-screen optimization, changing the desktop resolution, deleting the 'options.txt' file from the game directory, resetting game options, performing a selective startup, and updating graphics drivers.

Disabling Full-Screen Optimisation

Full-screen optimisation is a feature in recent releases of Windows 10 that allows the operating system to optimise video quality and performance when games are running in full-screen mode. However, despite its benefits, this feature is known to cause problems with some computers. Disabling full-screen optimisation can be done in the following way:

• Locate the executable file of your game or launcher. You can do this by right-clicking on the executable and selecting "Open file location".
• Once in the directory of the executable, right-click on it and select "Properties".
• Navigate to the "Compatibility" tab and check the option "Disable fullscreen optimisation". Press "Apply" to save the changes and exit.
• Now, launch the application again using the same exe file and check if the problem has been solved.

Changing Resolution

The error “Couldn’t switch to requested monitor resolution” occurs when a game client is unable to scale to the resolution set in the configurations or the resolution in which the launcher is trying to launch. This error is common, especially on Steam.

This method targets the dialogue of the error message. The message says that the computer failed to switch to the monitor resolution. Changingsection-break> Changing the resolution of your Windows and then trying to launch the game will prompt the game to launch in the set resolution and hopefully solve the problem.

• Right-click anywhere on your Desktop.
• Select "Display Settings".
• Choose a lower resolution than the one already set.
• Save changes and exit.
• Try launching your game and see if the problem is solved.

Deleting 'options.txt'

Deleting the 'options.txt' file is one of several workarounds to fix the "couldn't switch to requested monitor resolution" error. This error occurs when a game client is unable to scale to the resolution set in the configurations or the resolution in which the launcher is trying to launch.

The 'options.txt' file is usually present in games like Minecraft and is found in the '\.minecraft' folder in the Java Edition or in the 'com.mojang/minecraftpe' folder in the Bedrock Edition. It stores all the options that are changeable in the in-game options menu and various other information the game needs to store after quitting.

To delete the 'options.txt' file, follow these steps:

• Navigate to the directory of your game. For Minecraft, it is usually something like "%APPDATA%\.minecraft".
• Once in the directory, locate the file "options.txt" and delete it.
• Now restart your computer and launch the game. The game might take an additional minute or two to load the default configurations.

Instead of deleting the file, you can also cut and paste it to another directory as a backup, so you can replace it if something goes wrong.

Another option is to modify the lines in the 'options.txt' file to the following:

• Graphicsfullscreen=True
• Graphicsheight=1080
• Graphicsquality=1
• Graphicswidth=1920

Make sure to match the width and height to your current Windows resolution.

Resetting Game Options

If you are encountering the "Couldn't switch to requested monitor resolution" error in Kingdom: Classic, there are several solutions you can try. Here is a detailed guide focused on the "Resetting Game Options" solution:

This solution is specifically for Blizzard games. If the previous methods haven't worked for your Blizzard game, try resetting the game settings using the Blizzard application.

• Launch the Blizzard application and click on the Blizzard logo.
• Navigate to Settings, then click on "Game Settings" from the left navigation pane.
• Click on "Reset In-Game Options" underneath the tab of the game where you are experiencing the error message.
• Make any other necessary changes and then exit the settings.

After resetting the game options, you can try the "Disabling Full-Screen Optimisation" solution on the Blizzard application. Here's how:

• Within the Blizzard application, select the game tab and then select "Options".
• Navigate to the "Open in Explorer" option and open the game folder.
• Right-click on the game's executable file and click "Properties".
• Select the "Compatibility" tab and check the option "Disable fullscreen optimisation".
• Press "Apply" and exit.

Finally, restart your computer and check if the problem has been solved.

This problem is known to occur with the new Windows 10 build, according to Official Blizzard support, and should be fixed using this method.

Selective Startup

The "Couldn't switch to requested monitor resolution" error occurs when a game client is unable to scale to the resolution set in the configurations or the resolution in which the launcher is trying to launch. This error is common, especially with Steam.

One solution to this problem is to perform a "selective startup" on your Windows PC. This can be done by following these steps:

• Press the Windows Key + R on your keyboard.
• Type "msconfig" and press Enter.
• Choose "Selective Startup" and uncheck the "Load startup items" option.
• Select the "Services" tab and check "Hide all Microsoft services".
• Click "Disable all".
• Click "Apply", then "OK".

Disabling all startup programs may also disable your internet adapter, so you may have to re-enable the adapter manually after restarting your computer if you cannot connect to the internet.

After performing a selective startup, you can try launching your game again to see if the problem has been solved. If the error message has disappeared, it means that there was either a service or an application that was causing the problem. You can start enabling programs in small groups and checking if the error returns to identify the specific culprit.
