Close Quicken !!! (This process won't work while Quicken is running!)
Check the Compatibility tab settings in your Quicken Desktop program icon:
In the Windows Start Menu right-click the Quicken icon. Select "Open File Location". This brings up a Windows File Explorer window. Right-click the highlighted Quicken shortcut line item.
or
Go to the traditional Windows Desktop and right-click the Quicken program icon.
or
Use Windows File Explorer, navigate to C:\Program Files (x86)\Quicken\ and right-click qw.exe
Now click Properties.
Select the Compatibility tab.
Uncheck all settings.
Windows 7, 8.1: Check "Disable display scaling on high DPI settings".
Windows 10, 11: Click "Change high DPI settings". Check "Override high DPI scaling behavior. Scaling performed by:" and select "Application" (also try the other available options repeating the entire procedure!). Click OK.
Be sure to uncheck the "Run this program in compatibility mode for [older Windows version]" setting.
Click the "Change settings for all users" button.
Click Apply and exit.
Reboot Windows.
Now start Quicken and see if that makes a difference.

Some additional tuning suggestions:

Try this workaround for 4k monitors

Unless absolutely required, try not to use "View / Use large fonts"
Try setting the bank account registers to use a different font style or size: go to Edit / Preferences / Register, click the Fonts button and try different fonts.
Try adjusting the bank account registers' row height: go to Edit / Preferences / Register, choose among the available Row Height choices: Compact, Comfortable or Standard
If all else fails, try changing Windows Control Panel / Display options for "Make text and other items … smaller or larger" to use a different scaling level, but try not to exceed 125%
