Is there a way to increase the resolutions on non-DOS games? A few of the games I have installed have a low resolution leaving a large bounding area around the game screens which makes the text on these games difficult to read. My laptop's resolution is 1920x1080 and I have Win 10. The following games have a small resolution on my screen:
Dark Fall: The Journal
The Black Mirror
Clive Barker's Undying
Arx Fatalis
Robin Hood: The Legend of Sherwood

Different games need different solutions.
Some games may have fan-made or official patches.

If you can not find any patches, try playing them at fullscreen mode, or at a lower global screen resolution setting.

Looks like no scaling is done.

Go to your laptop's graphics card control panel, find an option called "Scaling" and make sure it's not set to Off.

For best experience you should select Maintain Aspect Ratio or similar. If you select full scaling, the screen will probably be stretched.

Let me know your graphics card model (or laptop model, if you can't find it) if you need more help.

Weird, I changed the resolution to 1280x800, one game seemed to work fine. Then I set it back to 1920x1080, and they seem to work fine now.

Sounds like you need to adjust the graphics settings of your computer, you should have scaling options and it seems now it's set to centered, change it to spread or keep aspect ratio.

More modern games that have graphicsengines that use vectordata for 3d can often be scaled up to suit your native resolution, just google it for the game on how to do it as it differs from game to game.
