Question Display calibration after connecting for Color Accuracy

[muftiazan]

Hello
I am considering moving my design to print and pursuing it professionally and for that I have considered buying a monitor which is wide-gamut and has color accuracy (deltaE<3) for which BenQ BL2420PT seems to be the right fit for my budget. Given these factors, I am learning that a display's color accuracy varies from machine to machine i.e. if I connect my monitor to a different machine, it's configuration will change and also that a display's color configuration degrades with time so calibration is required every 6 weeks or so. Given these factors, if a Pantone valitdated(or similar) monitor ships with accurate configuration and I connect to my PC, do I need to calibrate it or does it remain calibrated?
Further, if the display is initially calibrated, will backing up it's color profile initially and re-using it after the configuration wears off in 6 weeks mean that I wont have to calibrate it again?
Since, I am new to it, I can only tell that color calibration using software is inconsistent and difficult and hardware calibration tools are off reach for a student like me.
Please guide me with the same
Thanks

You WILL need to recalibrate occasionally, and a hardware device IS strongly recommended.
Monitors change as they age. The numbers you use today will not be the same in 2 months, and will not be the exact same in a year.

Hardware device is recommended because eyeballs and software just isn't good enough. What looks good at 9AM is not the same as what looks good at 9PM. Ambient light changes.

I have another question. The 2420PT is advertised with dealtaE to be less than 3 and in contrast, another wide gamut display EW277HDR is not. Is it possible for me to calibrate the display to have deltaE < 3 or is that not necessarily true for all wide gamut displays?
