A big shout out to the DNG engineering team.
Thank you for a complete popup window including all of the selector buttons with your DNG 9.4 release.
Well it is now February and I am having the same trouble with DNG 9.4 so clearly nothing has been done about this issue.
DNG is for converting RAW to DNG and clearly most people doing this have high res monitors.
Changing resolution also does not help.
Here are 2 screenshots to illustrate the problem
This is Win 10 on a Dell XPS 9550 with UHD screen.
Help someone please otherwise I need a magnifying glass to convert
I see that you are having an issue concerning the size of the popup window. The issue mentioned in my original post was concerning how much of the popup window was visible. In that case, the bottom section was cut off. The area with the command buttons (About DNG Converter... - Extract - Convert - Exit) was not available.
The resolution of my screen is set to 1920x1080. That resolution works for icon and text sizes, for me anyway. Previously, I was unable to use the command buttons but now all is good.
Best of luck for you to get resolution to your issue.
