You don't mention what kind of monitor you bought, but I will assume
that it is an LCD.
If so, one of the differences is that many LCDs have a very spiky
spectrum (more so than the doped red of old CRTs). Individuals
see colors that are very spikey differently since there is variation
from one set of eyeballs to another. It is possible that even if
you had the monitors set to the same white point by the meter
that they would look different to you.

cheapo color meters (colorimeters) that have been designed for rec709
usually pretty good. You would want to make sure though that you are
designed for monitors, not a general point and shoot, because the
and spectrum could cause measurement errors in a non-monitor

Not exactly. White point adaptation of the eye is the key and
But you can help it along. Having a D65 light source can sometimes
adjust to what the 'normal' white should be. Don't just look at a
on the monitor. Use several images each of which have substantial
them but have warm to cool timings. (so the whites look different to
your monitor). If all cases still appear pinkish, another cheat is
a tungsten backlight to the monitor (the surround brightness should
10% of the monitor) and to change the bezel and surround
of the monitor so that is a little warmer grey. This should make the
see the monitor as a little cooler than the surround and the 'pink' feel
may go away.

Yes, that is Evil.
