Some applications look good only when run in fullscreen. If you are watching a movie or playing a game, you’d want to use the entire screen space for the app. However, some of the Windows 10 OS users complain that they face different type of Windows 10 fullscreen problems & issues. Sometimes, it won’t go fullscreen, sometimes the fullscreen covers only a part of screen while at other times it just goes to a maximized window instead. Let’s see some steps that may help you troubleshoot the issue.
Windows 10 full screen problems
Confirm that Game full screen setting is turned On
Upgrading the operating system is sometimes a terrible task and certain things go wrong. If you are not able to run the games fullscreen, you may want to check the games’ settings. Most of the games have a setting of turning ON/OFF the fullscreen mode. See the status of fullscreen mode in the games that are not able to play fullscreen. If it is OFF, turn it to ON.
Note that not all games provide the setting but most games do. While you are at it, you might check the resolution as well. Try changing the game resolution from inside the Game Settings a few times to see if it works. Try increasing the resolution first and then see if Windows 10 fullscreen problems & issues go away. If increasing or default resolution does not work, try reducing the resolution a bit to see how it affects the fullscreen issue. If you see any improvement, you may reduce it a bit further to see if you can play it fullscreen without losing out on details.
Check Windows 10 Display Properties
Every operating system has a default resolution. When you upgrade on the previous resolution, the resolution already set is carried forward to new installations. In case of clean installations, the operating system determines best resolution for your display and sets it to what it thinks is best. When this display resolution conflicts with that of games, you may not be able to play games fullscreen.
To know the minimum resolution supported by a game, check out its system requirements. It could be printed on the game DVD. If you downloaded the game, check for email that confirms your purchase. If you still can’t find the system requirements, check with the customer support.
This section’s summary is that if you are facing Windows 10 fullscreen problems & issues, you have to check that Windows 10 is supporting the resolution that the game requires. Suppose the game requires 360p and Windows 10 is 780 (by default, Windows 10 is 1024 by 768 for regular displays), there will be conflict. You will then have to see if your copy of Windows 10 can lower the resolution to 360. If not, you will always get the game in a windowed mode. You may or may not be able to maximize the window.
Another takeaway from this section is that most games need to be upgraded as they still run on lower resolutions while most of todays’ operating systems, like Windows 10, support much higher resolutions. That could be a reason why you cannot play games fullscreen in Windows 10.
Upgrade your Graphics Card Drivers
When you upgrade via a clean install, Windows 10 installs generic drivers for most of your hardware. You can try installing the original device driver software if you still have it. It has helped some users. If installing original device drivers does not help, you may also try your luck by upgrading to latest device driver software available on the manufacturer’s website.
Windows 10 Text and Font Size
This may not make a difference, if nothing works you may want to try this. I do not believe this is going to make any difference. If the font size on your Windows 10 computer is set to more than 100%, then some users have reported that it creates Windows 10 fullscreen problems & issues.
Many users often increase the font size using the slider in Display Properties to scale it up a bit so that the new GUI is not hard on eyes. Click on Settings and then in the window that appears, click System. The very first option in the left pane is called Display. While selecting that option, see the right pane to check if the display is scaled up or down. It should be showing 100. If not, move the slider to make sure the display fonts are set to 100% and not more.
You may also try changing the default display if you are using more than one.
