Jan 2022 and the problem still exists and is hugely annoying. I'm running 2 HDMI in 1920x1080px on MacOS 12.0.1 (Intel).
I guess either Garmin does not care or they have given up with the software. The Mac AppStore is also not up-to-date and is one version behind. They've given up on Mac.
Have this problem as well.
I just use it on my laptop screen, click the window and then ZOOM. The icons go to regular size, then I drag the window over to my external monitor. As long as I don't resize the window, the icons remain the correct size.
not the best solution, but it helps.
2024 - The issue still persists like a serial pest in the carpark.
Has anyone solved this problem?
Happy 2025 and this is still happening. Is Garmin ever going to solve this??
No, BaseCamp development stopped years ago.
