That makes sense. Through I would rather have a professional level
monitor at 1080p then 4K.  Color depth, accuracy and text contrast
matter a lot  more than resolution when it comes down to it through.
And frankly 4K pro is a lot more expensive due to being cutting edge.
And yes text contrast is important for programming or other contrast
in forms of scaling/rendering text.

I would make the same argument about keyboards as well in that
I would rather have a mechanical keyboard rather than any laptop
keyboard. And frankly a great keyboard is a very underrated
similar to the above text issues for monitors.

Through  Intel has at least in my view historically been a little too
conservative when updating to new buses or hardware versions
but it doesn't surprise me,
