When I mean pro level I mean anything that can be used professionally
or is good enough. You can find budget versions of these monitors at
below $500 for 27 inches these days. The higher end ones just have
better color depth and other things. If you shop around you can possibly
find it cheaper used or on sale and I would doubt that the ones above
budget level get much better for text. However for text they would be
read then a consumer display.

Not actually, scaling is not what you think I mean. I don't
mean it scales well to fit the screen i.e. text is too small
but readability of text. This is where better dpi and text
settings come in. For example ereader displays are very
readable because of their high dpi to screen ratio and
good text contrast alongside other screen settings.

Of course the biggest problem with buying monitors these
days is its basically a case by case purchase.
