I do not believe you can do anything about this if they are both on the same computer being viewed with the same monitor. The issue apparently goes to the native resolution of your monitor assumed 1920/1200 and scaling.
This type of situation came up in Premiere Elements 13. But, it is my dusty recollection that it was corrected in the 13.1 Update for 13. Please see the following thread and especially the comments of PRE_Help (Adobe Premiere Elements Help Team) who stepped up to make comments post 14.
This is not Adobe. Rather essentially a user to user forum. The frequency of the Adobe presence in this forum is undefined. The presence is more likely for a question related to the just released version. Let us see if PRE_help enters your thread with the Adobe current definition for this matter.
We will be watching for further developments.
Thanks for your help. I have read the Premiere 13 thread and understood Adobe did not want to help.
I have figured out a solution just now: first I changed my screen resolution to 1920x1080 before start Premiere Element; then I load Premiere and the font is correct this time; the last step is to change back my screen resolution to 1920x1200 and drag the Premiere window to fill up entire screen. Bingo! So Premiere Element is apparently able to handle the 1920x1200 resolution, but it uses a funny algorithm at loading time which makes it not work.
Thanks for the follow up.
Very interesting troubleshooting and workaround for your 1920 x 1200 monitor display and Premiere Elements 14 font size issue.
If you use your workaround and then save close the project and then reopen it with 1920 x 1200 monitor setup, what are you looking at - font OK, or font large?
Also, do you have to do the workaround for each new project?
Great job of follow through. We will be watching for further developments.
