Lightroom Classic opening in giant text/display format

[defaultfbzz1o2bwa4q]

I am opening LC (10.4) for the first time with a new laptop and extended display, and I've never experienced this before with my old extended display setup. When I open LC (Windows 10) on the larger monitor (set to proper resolution), LC opens in this giant format, as if for the visually impaired. I can't find any settings to change it to regular. The menu titles, all text, all tool boxes: GIANT. I'll attach a screenshot - for perspective, see the text size of the menu in the upper left. This is the only thing that opens to normal scale. 

If I drag LC over to my laptop display, it displays at normal scale. Suggestions?

Please post your System Information as Lightroom Classic (LrC) reports it. In LrC click on Help, then System Info, then Copy. Paste that information into a reply. Please present all information from first line down to and including Plug-in Info. Info after Plug-in info can be cut as that is just so much dead space to us non-Techs.

What is the setting of Edit > Preferences > Interface > Font Size?  Try Automatic, Small, and Medium.

Thanks for that tip, @johnrellis . I changed the Font Size to Small and had to close LR and reopen it before it took care of the display on the extended monitor. But it worked like a charm. It didn't do anything thing to the font size of the Menu at the top, but I can live with that.  

Thanks,
