There are actually two issues here. You definitely should have two screens for productivity reasons. However, you should not be running Archicad over two screens. One screen is used for ancillary programs (email, spreadsheets, web pages, etc.) One screen for Archicad. I actually run Archicad on a 43" screen (UHD - 4K TV) and have a 27" monitor next to it. Not having to zoom in and out so much speeds things up dramatically, and for older eyes, is much more comfortable. Given that a 43" TV is likely the same price as a 27" monitor, it's worth considering.

I've been used to a 49" 5120x1440 monitor, but that got too small for me, so I just recently added a 27" next to it. For me it helps to work with AC, Rhino and Grasshopper simultaneously, maybe Solibri too, plus I get to see my email, calendar and system monitoring tools too all the time with that extra 27 incher.
