Archicad 26 and DPI issue on 4K monitors under Windows 11

Paul King

Has anyone solved the issue of ArchicCAD 26 displaying with 'fatter' lower resolution linework than earlier versions on same workstation (i.e. same hardware, same Windows version, same graphics driver etc) ?

This is with Archicad 26 version 4019 and using same 'Advanced Redraw Options' settings in Archicad 26 as with Archicad 24.

 

The consequence is that adjacent linework in detailed areas visually merges together into a blob far sooner than it normally does when zooming out, and small differences in line weight are hard or impossible to distinguish.

Do those gaps appear and disappear as your zoom? I suspect the fill splitting from the border would be due to the fill being drawn seperately from the border, rather than as a single entity. This means that if you are working at an odd scale factor, one may get offset left while the other right when mid pixel. Alternative coding would be to fattern or thin lines by the half pixel, but that may cause lines to disappear, which is even less desirable. I would always recommend that you only ever use 100% or 200% scaling on monitors, else you are depending on the software to determine pixel splits and you lose sharpness.

I think the idea is that drawing linework/fills etc should not be scaled at all, with display scaling functionality applying only to application text/menus, mouse pointers/dynamic feedback graphics etc
