yes, my favourite monitor after so many years (6 years+ monitor)..
during COVID-19 2020, I went back to MY and forgot to turn off my monitor, end up I stuck in MY one year, my monitor 24/7 on max brightness for one year until I went back to JP
luckily the monitor still fine till today, just need to recalibrate the color a little

yea, I was actually quite surprised it was still running fine after such abuse hopefully can last another 5+ years, no plan to retire yet

tbh, if the monitor is still ok and u are used to the sharpness of the text on 25" 1440p, no need for upgrade unless u are really in need a lot of screen estate.

I felt that going bigger (not 27") with the same 1440p kinda view would be best
best if the pixel per inch is similar or higher than the U2515H (117 ppi)? for e.g. U3219Q is at 140 ppi

27" on 1440p u get less ppi, no?
