The error “Couldn’t switch to requested monitor resolution” occurs when your game client is unable to scale to the resolution which is set in the configurations or the resolution in which the launcher is trying to launch.
This error is a very common one with it popping on every random game but the most popular client where this error pops up is Steam. We have listed down a number of different solutions for you to try out. Start with the first one and work your way down accordingly.
Solution 1: Disabling Full-Screen Optimization
Recent releases of Windows 10 include a function for people who sport. This characteristic is called “Full-display screen optimization” and while it’s miles enabled, it lets in the operating system to optimize the video first-class and overall performance while the video games are going for walks in full-display mode. However, notwithstanding it doing any right, this selection is thought to cause troubles with the pc. You will get the error circumstance below discussion with mild periods. We can disable this and notice if the hassle is solved.
- Locate the executable file of your game or your launcher. You can right-click on the executable and select “Open file location”.
- Once you are in the directory of the executable, right-click on it and select “Properties”.
- Navigate to the Compatibility tab and check the option “Disable fullscreen optimization”. Press Apply to save changes and exit.
- Now launch the application again using the same exe file and check if the problem got solved.
Solution 2: Changing Resolution
This workaround targets the very speak of the error message. The message says that the computer did not transfer to the display resolution. We will trade the resolution of your Windows and then try launching the game. This will, in turn, spark off the game to release inside the set decision and optimistically, remedy the trouble.
- Right-click anywhere on your Desktop and select “Display Settings”.
- Now select a lower resolution other than the one already set.
- Save changes and exit. Now try launching your game and see if the problem got solved.
Solution 3: Deleting ‘options.txt’
Another workaround which seems to work is to delete the report ‘alternatives.Txt’ out of your recreation listing. This file is normally present in video games like Minecraft. It is a document which stores all of the options which can be changeable in the game. It may be edited with any textual content editor however, if we delete it, the software will locate the file as missing and will recreate a default one. This answer will paintings if your document is corrupt and is causing the error message.
- Navigate to the directory of your game. It will most probably be 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 when it is loading the default configurations.
- Now check if the error message still persists.
Tip: Instead of deleting the file, you can ‘cut-paste’ it to some other directory so you can replace it back if something goes wrong.
You can also try modifying the lines to this:
graphicsfullscreen=True graphicsheight=1080 graphicsquality=1 graphicswidth=1920
Make sure that you match the width and height to match your current Windows resolution.
Solution 4: Resetting Game Options (Blizzard)
If all the above techniques don’t work for your Blizzard game, you can try resetting the game settings using the Blizzard application. Then you could carry out solution 1 on the software and hopefully, it will likely be solved. This hassle takes place in the new Windows 10 build consistent with Official Blizzard guide and is supposed to be fixed the use of this approach.
- Launch the Blizzard application. Click the Blizzard logo and click Settings.
- Now click “Game Settings” from the left navigation pane and click Reset In-Game Options underneath the tab of the game in which you are experiencing the error message. Press Done after making the changes and exit.
- Now within the Blizzard application, select the Hearthstone tab and select Options. Now drop down to the option “Open in Explorer” and open the Hearthstone folder. Now right-click on exe and click Properties. Select the Compatibility tab and check the option Disable fullscreen optimization. Press Apply and exit (this is the same step as solution 1).
- Restart your computer and check if the problem at hand got solved.
Solution 5: Selective Startup
It is a known fact that there are several startup programs which hinder the many games and causes certain errors to take place. The best way to solve this problem is to disable those startup programs.
- Press Windows + R, type “msconfig” in the dialogue box and press Enter.
- Once in the settings, select “selective startup” and uncheck the option “Load startup items”. Press OK to save changes and exit.
- Navigate to the Services tab present at the top of the screen. Check the line which says “Hide all Microsoft services”. Once you click this, all Microsoft related services will be invisible leaving behind all the third-party services.
- Now click the “Disable all” button present at the near bottom at the left side of the window. All the third-party services will now be disabled.
- Click Apply to save changes and exit.
- Now navigate to the Startup tab and click the option of “Open Task Manager”. You will be redirected to the task manager where all the applications/services which run when your computer starts will be listed.
- Select each service one by one and click “Disable” at the bottom right side of the window.
- Now restart your computer and check if the error condition still persists. If the error message goes away and you are able to play your game without any problems, it means that there was either a service or an application which was causing the problem. Enable a chunk of these and check again. If the problem comes again when you enable a chunk, you would know who the culprit is.
Final Solution: Updating Graphics Drivers
If all of the above strategies fail, it probable means that there may be a problem with the cutting-edge drivers established in your laptop. If you have corrupt or old drivers, it could be the cause why your sport fails to switch to your computer’s default decision. Now there are two approaches via which you could update the drivers: either manually or robotically. In manually, you need to for my part down load the motive force after looking for it at the producer’s internet site.
Before updating drivers, we are able to take a look at if putting in the default drivers clear up the problem for us.
- Boot into Safe mode. Type “devmgmt.msc” in the dialogue box and press Enter. Here navigate to Display Adapters, right-click on your adapter and select Uninstall Device.
- Boot your computer into normal mode, press Windows + R, type “devmgmt.msc” in the dialogue box and press Enter. Most probably the default drivers will be installed. If not, right-click on any empty space and select “Scan for hardware changes”. Now check if the game works without any problems. If it does without any problems, good for you. If it doesn’t, carry on.
- Now there are two options. Either you can search online for the latest driver available for your hardware from the manufacturer’s website such as NVIDIA etc. (and install manually) or you can let Windows install the latest version itself (search for updates automatically).
- We will take a look at installing manually. Right-click on your hardware and select “Update driver”. Select the first option “Search automatically for updated driver software”. Choose the second option if you are updating manually and select “Browse for driver” and navigate to the location where you downloaded.
- Restart your computer after installing the drivers, launch the game and check if this solves the problem.
