Note the Asus display linked to by Square Peg can only display 16.7 million colors.
That essentially is saying it can only display 8 bits of color per red, green, and blue color channel.
Here's how that works out.
The 8 bit
digital number, 11111111, is 256 in our normal - base 10 - number system.
So 8-bits can display 256 discrete shades of red, 256 discrete shades of green, and 256 discrete shades of blue.
256 x 256 x 256 = 16.7 million (rounded off).
Digital cameras make image files (Raw files) that are 12-bit or 14-bit files which can code way more discrete shades of color.
12 bits can display 4096 discrete shades of red, of green, and of blue or 4096 x 4096 x 4096 = 6.87
trillion colors.
The main plus for you about that Asus display is that it is an IPS (In-Plane Switching ) type of display that has wide color accurate viewing angles.
You could spend less getting a TN (Twisted Nematic) Type display, but TN has such narrow color accurate viewing angles that with a large display you can't see accurate colors across the entire screen.
If you want the colors in your photos to be displayed accurately, regardless the complexity of your edits, you would want a 10-bit, or more, display.
But as the bit depth capability of a display goes up the more a display costs.
Also. Even that inexpensive Asus IPS display will have to be routinely calibrated for it to continually accurately display the colors it can display.

So I recommend a basic display calibration tool that you would use about once a month:

Even better would be a:
