OOTP can accommodate many different monitor sizes, but some users may experience issues on high-resolution monitors where the scaling results in extremely small fonts and renderings.

To fix this issue, click on Settings either on the OOTP main page, or if you are in a game, from the File dropdown menu, choosing "Settings". When the pop-up opens, select the "Expert" tab. Where it says, "Use Windows DPI scaling (*)" change it to "Always Off". To have the game incorporate these new settings, close OOTP completely and then reopen it. The font and scaling should now be restored to your expectations.
