Hi, I used solution one up to a point. After opening Properties and clicking on Compatibility I had to click on the CHANGE HIGH DPI SETTINGS box toward the bottom. Once there under High DPI scaling override click the square to the left then for Override high DPI scaling behavior. Scaling performed by: In the drop down menu choose System not System(Enhanced)*. After that click Apply, Ok. I knew it finally worked when I opened QB and the initial opening icon was 3" across instead of 1".
This is the only solution I've been able to find, I had this problem with Desktop Pro 2018 and had to relearn the solution after downloading the 2021 version. I didn't have this problem with my old laptop but I upgraded and now I have a Dell computer with 10th gen intel core i7. I am not a computer person so I don't really know what that means and if it's helpful.
* Update* For about a month I used System (Enhanced) but I had issues with dropdown menus disappearing, I'd have to arrow down to my choice and hit enter instead of using the mouse to just click on it. The formatting is finally back to what I was used to in QB Pro 18 and earlier versions.
Best!
