I came across many of people or students complaining about inability to run DOS in “Full Screen” mode with Windows Vista and Windows 7 operating system. I critically faced this problem recently when I was supposed to perform some C/C++/Java Console Application Programs on my system. I observed some of the solutions for this as listed below:

Solution

1:

• Click Start and type CMD, but don’t hit enter or click on cmd.exe. • Right-click cmd.exe above and choose Run as administrator. • Now open cmd.exe once again and right click on it’s title bar. • Go to “Properties–>Layout–>Width • Set the Width as 1500 pts and Height 300 pts • Now got to “Font” tab and select “Font Size” as 28 pts.

After doing the above steps, you’ll find out that you’ll be able to use your DOS in “Full Screen” mode.

From now on Command Prompt will open at a size that fills the screen. It accomplishes this by as many rows and columns of characters as necessary to fill the screen. If that’s not the kind of full-screen you wanted, you can put Command Prompt back to normal thus:

• Right-click its and choose Properties. • Click the Layout tab • Set Screen Buffer Size’s Width to 80 • Set Window Size Width to 80 • Set Window Size Height to 25 • Click OK

I’m guessing that what you really want is to have the command prompt literally fill the screen without changing its 80×25 layout. In XP you can toggle this mode by pressing Alt+Enter. Doing that in Vista just gets you a message “This system does not support full-screen mode”. And it’s true; the Windows Vista Display Driver Model [WDDM] precludes support of the necessary video mode.

There is a kind of solution, and it’s even recommended by Microsoft. They suggest replacing the driver for your graphics card with the equivalent XP video driver. You’ll lose the ability to run Vista’s spiffy Aero interface if you do so, but you’ll gain back the ability to run full-screen DOS programs.

Another easy way to do this is to disable your video drivers for a while to enable DOS in full screen. Here are some steps that you can follow:

• Go to your Desktop • Right Click on your “My Computer” icon. • Click on the option “Manage” • Now in Manage Window, at the right panel, click on “Device Manager” option. • After clicking on that, you’ll get “Display Adapter” option, you need to double click on that. • All you can see now is the name of your “Display Drivers” below “Display Adapter” option. • Right Click on that name and select “Disable” • You’ll find that your screen resolution is changed, now you can see your DOS window full screen • After finishing your work on DOS you can “Enable” your drivers by following same path.

Putting games in full screen mode can help with immersion, but what if Windows doesn't let you do that?

Running your games in the full screen not only helps avoid distractions but also allows you to fully immerse yourself in the gaming experience. It also leads to smoother gameplay as your system dedicates its resources exclusively to running the game. But what if your Windows computer won't open your games in full screen?

To help out, we have listed some effective solutions that should get your games to run in full-screen mode on Windows.

1. Use a Keyboard Shortcut to Enter Full Screen Mode

Using the Alt + Enter keyboard shortcut is the easiest way to enter full-screen mode in your games. This hotkey is compatible with nearly every game on Windows. Hence, it’s the first thing you should try.

Pressing Alt + Enter again will switch your game back to windowed mode.

2. Check the In-Game Display Settings

Most games include a dedicated display settings menu that lets you specify whether you want to run the game in full screen or windowed mode. You need to review this setting for your games to ensure that full screen mode is selected.

3. Disable Full Screen Optimizations in Windows

While the full screen optimizations on Windows are intended to improve your gaming experience, they can occasionally result in games not opening in full screen mode. If that's the case, disabling full screen optimizations for your game should help.

1. Right-click on your game’s shortcut and select Properties.
2. Switch to the Compatibility tab.
3. Tick the Disable fullscreen optimizations checkbox.
4. Hit Apply followed by OK.

4. Set the Display Scale to 100%

Certain games may face difficulties entering full screen mode when the display scale on Windows is set higher than 100%. Setting the display scale at the recommended value can help ensure that the game is rendered at the native resolution of your monitor, without any scaling or resizing applied by Windows.

To change the display scale on Windows, open the Settings app and navigate to Display. Click the drop-down menu next to Scale to select 100%.

5. Use the Compatibility Mode

Another thing you can do is run your game in compatibility mode, especially if it’s an older game. Here’s how to do it.

1. Right-click on your game’s EXE file and select Properties.
2. Switch to the Compatibility tab.
3. Tick the Run this program in compatibility mode for checkbox.
4. Use the drop-down menu to select an older version of Windows, such as Windows 8 or Windows 7.
5. Click Apply followed by OK and then open your game again.

6. Disable Any Apps With Overlays

Occasionally, overlays from apps like Discord, Steam, or GeForce Experience can disrupt the full screen functionality of certain games, resulting in issues. To check for this possibility, you can temporarily disable the GeForce overlay, the Discord overlay, or any other software that shows overlays to see if this works.

7. Perform Some Basic Windows Fixes

If your games are still not opening in full screen at this point, you can try a couple of basic fixes and see if they work.

• Update Your Graphics Driver: Outdated or incompatible graphics driver on your PC can keep games from running in full screen mode at times. You can try updating the graphics driver on your Windows PC via Device Manager and see if that solves your problem.
• Run the Game as an Administrator: In some cases, running the game as an administrator can also help fix the problem. If this method proves effective, you can configure your game to always run as an administrator on Windows.

Experience Gaming Like Never Before With a Full Screen Advantage

Playing games like Valorant, FIFA, Battlefield, and others in windowed mode can greatly dampen your gaming experience. Hopefully, that’s no longer the case, and one of the above tips has gotten your games to open in full screen mode again.
