Apologies, I've only just noticed this request. Unfortunately I don't have a large spreadsheet that I am able to share (even blurred) on a public forum. However, I often work with both data and financial spreadsheets many of which have over 200 columns and thousands of lines with Power query, Pivot tables etc. Initially I was having to deal with these on a 13" laptop screen which, on several occasions, almost resulted in the laptop exiting through a window. As I've said elsewhere, the 49" Samsung monitor isn't cheap but I don't regret it for a minute; I purchased it from HERE.
