Lightroom scale issues on high resolution screen

[TeaForMe]

I recently got a HP-computer with a high resolution screen (3840x2160). When I installed Lightroom I experienced that the scale was much smaller than it had been on my old computer. I have tried to fix this by changing Preferences/Interface/Font size, but it didn't help. I have Windows 10 and the latest version of Lightroom. What should I do? Please help me!

You need to close and restart LR after changing the font size in Preferences.

I did that and it still didn't work. I took the largest font size I could, but there was no difference.

If there's no difference after changing the font size your Preferences file may be corrupted. Please try resetting it as outlined here:
