I answer myself. I bought a 4K monitor to have something similar to MacBook retina screen with HiDPI.
My big error didn’t look MacBook specs, my early macbook 2013 doesn’t support 4K. Thanks to SwitchResX I have 4K at 30Hz. I’m impressed with “retina” on my 24" monitor.
Finally, I prefer macbook screen, but now I have something bigger with more quality than a traditional monitor.
Of Course: ViewSonic VX2475SMHL-4K
I hate Samsung monitors, bad experiences.
The alternative was a Dell, but I had good and bad experiences, but globally sense was bad.
