MSFS 2020 Pop Out Screens--Trying One More Time

I have previously posted about this deal breaker problem, but didn’t get suggestions that were what I hoped for. In some a/c I fly pop out screens take up half my monitor making them too bug to be useful. This has happened to a/c that previously had much smaller pop out that fit in the upper left corner of the screen. What’s troubling is that the huge screens are now occurring in a/c that had normal, small screens just a few weeks ago–the Headwinds A330 and B787 for example. I flew both those a/c many, many times with normal screens but now are huge. The Asobo B737-10 is another, also the PMDG B737-700. Flew all these a/c lots of hours and they were fine, now all have the huge pop outs and are unusable to me.
The suggested fix I got previously was to acquire the Pop Out Manager app online. I don’t want to do that because I’m convinced it is something in my system setup or in the sim itself and should be a simple fix if only I could find it. Plus, I am reluctant to add programs to the sim.
This problem seems to be growing. My hope is someone what has had this problem and fixed it sees this post.
Thanks in advance.
