Windows 10: DirectX 12 Exclusive Fullscreen with Different Aspect Ratio

Since Exclusive Fullscreen functionality is not a feature in DirectX 12, this creates a problem when playing games in a different Aspect Ratio than the display. I have a 16:9 Display, but I like to play games at 21:9 in Fullscreen Mode. DirectX 12 only allows the use of a different Aspect Ratio in Windowed Mode, which leaves my desktop visible in the background. We need a fix that will create the Letterbox black bars for different Aspect Ratios when playing in Borderless Window Mode.

Change monitor aspect ratio

The aspect ratio of your monitor is fixed and can't be changed, because it depends on the arrangement of the pixels on the screen.

When you display an image on your monitor whose aspect ratio is different from the aspect ratio of your monitor, what you'll see depends on how different the aspect ratios are. Usually, you see black bars on the top and the bottom of the screen, or on the
left and the right, a familiar appearance known as 'letterboxing.'

Windows 10 Graphics Rendering Aspect Ratio Issues

As an update since I got an email saying "Your question has not been marked as answered". As already mentioned in a previous post, it has NOT been answered nor resolved. The problem as mentioned was the drivers and the software no longer offers "Scale Full
Screen" option.

The problem is between Microsoft Windows 10 and Intel Driver Software. The issue is when a game starts no matter the time it was made or DirectX used, it keeps the aspect ratio in Windows 10 1366x768 inserting black bars on the left and right side, rather
than stretching games to full aspect of the screen.

Already tried numerous tips, tricks, and suggestions from Intel website, NVidia Website, community forums, and here on Microsoft forums. All suggestions failed. Simple answer I suggest Microsoft Technical Dev team is

A. Collaborate with Intel on HD 4000 drivers and software to resolve compatible issues

B. Focus on aspect ratios in the development

C. Allow aspect ratios to change when programs start not requiring the native resolution to rule.

Will continue working with Intel Community Forums, Windows Forums and NVidia.
