A lifetime ago when I was still programming on two 1280 × 1024 monitors I’ve published a post about the IDE layout I was using at that time (in Delphi 2006).
I was always saying that there’s only one reason why a programmer should use two monitors – because (s)he has no place for the third one! So when the opportunity knocked I did the same – cleaned up some place on the desk and installed a 1920 × 1200 monitor in the middle.
As the 1920 × 1200 monitor is much larger than the old 1280 × 1024, I’ve managed to lay out Delphi on the main monitor only (monitor #2 is primarily dedicated to mail and monitor #3 to IM and StackOverflow). As you can see I’m still actively using ModelMaker Coder Explorer (a must have add-in for Delphi IMHO). I’ve also started using Documentation Insight to document the code and I like it. Font is Consolas at 11 pt and the code window is big enough for 42 lines with 108 columns (margin is set to 90 but I’m not strictly wrapping before it; sometimes the code – and specially in-line comments – is allowed to flow past this margin).
In debugging mode, code window is reduced to 90 columns so I can display CPU windows and two extra memory windows. MMX and Documentation Insight are replaced by the stack tract, watches and local variables.
