Large HFR numbers

Sometimes when in Frame and focus a large HFR number will appear in the image window. I’m not sure what I do to get it, but I like it a lot. It’s easy to read without finding my reading glasses. Is there a way to get it to stay there all the time? The numbers in the image statistics are really small for old eyes. I’ve looked around in the settings but don’t see anything related…any ideas???
Thanks

When you have image history enabled.

Thanks! I have been turning that on lately…would explain why the big number has been showing up!
