Highlighting Non-duplicate rows across two tables of data

Hi,

I have two tables with data in them in A1:D20 and F1:I20
These two tables will mostly contain the same information, but each month data from D1:D20 will change either in the form of one cell or maybe entire row(s) being added or deleted.

Im looking therefore to compare each row in F1:I20 with all the rows in A1:D20 and if they either contain amended data or entirely new row(s) colour them red. I can do this comparing two columns, but when it comes to a range of cells Im struggling and my google skills dont seem ot be working.

Any help appreciated.
