Dear John
First, are you running the latest code release of ACS? From ACS main screen's menu bar, select Help --> About and you compare your release with mine below which is the latest (or almost latest) release. If your ACS release is too low, please download and use the latest code.

If it has the same release or newer, then start a PC5250 session and from its menu bar, select Communication --> Configure. Then click on Font item under Screen and you see this dialog box below. I suggest you play around with the 2 options: Fixed Font and Font Scaling to see if it helps address your issue or not?

You can also select a font style that pleases your eyes as well :
