I had a 1920x1080 running from a T430s using VGA, and the picture was
not nice, especially areas of (ostensibly) homogeneous colors. I tried
various fancy VGA cables (thick shielding, gold plating -- our IT has a
lot of these around), but they did not help much. So when I upgraded to
a new, larger monitor, I bought a miniDP-DP cable and has been happy
ever since.

But I am still glad that Thinkpads have VGA ports, if I want to use my
own laptop for a projector that seems to be the most common alternative.

Best,
