Screen Resolution

Good evening Pulse, I wanted to know what is the optimal resolution for Rekordbox, on my surface everything is very clear and well defined, on my Dell2k monitor, the situation changes, if I set the DPI at 100% the situation improves and the interface has the correct size, if I set the DPI to 125%, which is the choice suggested by windows everything is much larger and not defined as on the internal monitor. What is the optimal resolution for high-definition screens?

Congratulations for this version 5.1.1
