1920 x 1080 will be fine. People have been using 1920 x 1080 screens for years. It's long been the standard for 23" desktop monitors.
4K on a laptop is stretching it. Cramming 3840 x 2160 pixels into a laptop screen means those pixels will be incredibly small - and everything displayed with them equally small.
As for colors, all displays need to be calibrated and profiled to display accurately. If you do that the right way, you can get a good screen to print match. But that's a big subject in itself.
Don't expect stellar performance from any laptop displays. There's good and bad, but a desktop monitor is in a different league.
It will work fine - I use three 22" 1080 x 1920 displays on my main desktop.
As D.Fosse pointed out, colour accuracy / predictability comes from calibration and profiling. In my view it would be better to spend a little extra on hardware and software to calibrate the display rather than spend it on a higher pixel resolution but then run it without calibration.
Thank you. Your response has been very helpful.
Thank you sir
