Not quite as good as 17.4", but better than 17.2.

Seriously, any screen will "work", but life is much better with a larger screen. Lacerte recommends 19" https://accountants-community.intuit.com/articles/1859732-2019-lacerte-system-requirements an I am sure that those who have added two screens wonder how they ever existed before. 

Just a very quick look at Amazon shows some 21" and larger starting at $90.
