Petercage: Noticing any of the old games I have that use DOSBox are all playing now in a tiny mode at the center of my screen with a large black border. Does anyone know how I can fix this? I don't mess around with DOSBox typically, just start the games out of GOG Galaxy.

BrandeX: Like me, it sound like you are playing on a TV or other display that doesn't have hardware scaling. In your video card control panel, set scaling to GPU. This should generally resolve issues that are related to device scaling. If not, you can force each one manually by editing the dosbox.conf file so that aspect=true, output= (anything besides surface, e.g. ddraw), and resolution = your displays maximum res.
Went in and changed Fullresolution to 1920x1080 (it was set to original), and so now it's a much bigger image but with slight black borders. Much better now.

My dosbox setup runs at full screen, no black borders anywhere. Find the .conf file and set these 4 lines:

fullresolution=640x480
output=opengl
aspect=true
scaler=none

Make a backup just in case.

Did you try setting the scaling to GPU in your video card control panel, as BrandeX suggested? That should fix your issue completely. Changing the fullresolution option in Dosbox is just a workaround. If you change your settings in your video card control panel, you should be good for all low res games (even non-Dosbox ones).

I found the problem, I had to go to the Nvidia Control Panel and select "Override the scaling mode set by games and programs." That fixed my problem. Thanks everyone for your replies.
