Apart from the fact that both displays in my setup have the same resolution and frequency, they seem to have different dpi values, here's the output from my system report (linux mint)
Monitor-1: DP-4 res: 1920x1080 hz: 144 dpi: 128 size: 382x215mm (15.04x8.46") diag: 438mm (17.26") modes: N/A Monitor-2: HDMI-0 pos: primary res: 1920x1080 hz: 144 dpi: 93 size: 527x296mm (20.75x11.65") diag: 604mm (23.8") modes: N/A Maybe that has something to do with it.
