Following this upgrade, I noticed a significant font rendering issue on the physical HMI screen. The issue: All text appears noticeably thinner and less bold than expected, which greatly affects readability. Strangely, in the TIA Portal V19 editor, the screen layout and fonts display correctly with the intended bold styling. Has anyone encountered this issue? How can I resolve this font rendering inconsistency between the editor and the physical panel? Thanks in advance for your help.

If it is ok, then you have a problem in the project you have been working with.

Test it with a non bold setting of some texts, do you see also differences? Its because I think the comfort Panels have problems with font families with bold fonts. Often the basic font families are also installed in the Panel WinCE and there are often no bold font integrated. So the system uses a substitute font and this will lead into a not wanted visual effect. (But I´m also not sure if his is a general behaviour or only in some Image Versions...) Bye Murof
