DOS-Box Change Screen Resolution

DOS Box Hint Screenshots

Sometimes we may want to play the old games with DOSBox in window and set the window dimensions.
To change the screen resolution of the DOS-Box window:
1. Find the options bat file in the folder where the DOS box is installed. By default it is in c:\program files\DOSBox-(version).
2. Find the the DOSBox bat file and run it.

3.  Find the string "Windowresolution=" and place/type your favorite resolution. 600x400, 800x600, 1024x768 and 1280x1024 should work. Check if fullscreen=false, if not, make it false like in the screen
4. For the DOSBox to recognize the resolution, the output must be changed to opengl, so find the string "output=" and place/type opengl like in the screenshot.

Save the file and start the DOSBox, it should be with the chosen resolution now. Aslo to automate what DOSBox start, check this post: DOSBox Automatic Mount
