I tried dpi.lv on my 2 monitors and my phone. It said: Resolution: 3360 × 2100 Diagonal: 13.3″ Resolution: 2560 × 1440 Diagonal: 13.3″ Resolution: 2160 × 1080 Diagonal: 13.3″ (my monitors are 15.5" and 27" diagonal, my phone is 6") Maybe I'm crazy for using my phone in landscape mode, but I'm not sure how I'm supposed to tell which of those measurements is a phone.
