I have a gorgeous hi resolution 2560x1440 monitor.
Several years ago, Lacerte support suggesting using it with the System(Enhanced) High DPI compatibility setting. It gave me most of the resolution, with no edge fuzziness, so I used it in 2018.
However, in the 2019 program, this setting caused the new "re-imagined" eSig tab to freeze. I had to go back to the lower quality "System" setting, that had substantial edge fuzziness.
The freezing for eSig appears to be back for 2020 for System(Enhanced).
What do others use for hi-res displays?
