You probably already know that but just in case. I use a multi screen set-up with 1x4K Display and 1xFull HD display as set-up for my work station. Both displays are set with different scaling for text so my old eyes can read.
When editing properties in IQanDesgin in the 4k display, the edit box location does not properly line-up with property title and the font size does not match the box height making it very difficult and sometimes impossible to edit. Problem become more and more profound as you go down the list of properties . Probably the other programs have similar issues also but I rarely use them on the Work station so I cannot comment.
